Wine Watch Wine Bar (Fort Lauderdale, FL): A welcome addition to a wine bar desert

Wine Watch is a "boutique" wine retailer located at 901 Progresso Drive in the Flagler Village section of Fort Lauderdale. The store, for me, has been characterized by a lack of external signage, a nondescript exterior, no visible/easily detectable entrance, and, once you enter, a wide range of wines from around the world scattered throughout the darkened interior on a mix of shelves, carts, boxes, etc. That being said, this is one of the few retail establishments in Florida where you can walk in and buy very old vintages off the shelf.

The store is well known for its winemaker dinners and other wine-themed events. Wine-tasting dinners, when held on site, were squeezed into a devoted area in the shop. There is no kitchen so these events were always a logistical challenge.

No more. As of June of this year, Wine Watch has opened an honest-to-goodness wine bar just down 3rd Street from the retail store.

wine shop
I was unaware of this development so when I went to last Thursday's Aldo Conterno dinner, and I got there early, I went into a bar down the street to pass the time. And, as in the case of the retail shop, there was no external signage to alert me to the fact that such an entity existed.

As it got close to the time for the dinner (and I saw no cars outside the retail shop), I called to double check as to where the event was going to be held. I was told at the wine bar across from the retail shop.

As I stepped through the door, this amazing tapestry unfolded before my eyes. Beautiful wood floor; OWC ceilings; front walls adorned with original bottle labels (many signed by producers); cork-and-bottle chandeliers; lots and lots of racks containing neatly stacked bottles; a well-appointed bar to the left front; beautifully appointed and apportioned customer spaces; and, in the distance, a full kitchen.

According to Andrew (Lampasone, Proprietor), the bar is open Wednesday to Saturday in the evenings and he is trying to get patrons acclimatized to that schedule. Friday night folks tend to bring great bottles from their cellar to share and Saturday is "Brown-Bag Day" for those willing to participate.

The wines on display in the shelves are available for purchase by the bottle but there is also a phenomenal by-the-glass program. For example, on the night after the dinner, they were going to be serving 1995 L'Evangile out of magnum by the glass. All BTG wines are opened fresh each day.

For our event, a long table was set up to the back left of the bar. The setup was pleasing to the eye. The one shortcoming was a lack of separation between the participants in the dinner and the other patrons. From time to time it was difficult to hear what the winemaker was saying.


I tasted three dishes from the kitchen and each was extremely good.




This is a welcome addition to a wine bar desert with the only other wine bar of substance (now heavily outclassed) in the area being Vienna Cafe and Wine Bar in Davie. I will be visiting this bar frequently.

Linden Vineyards (Linden, VA): Winemaking and wines

After treating the viticultural aspects of Linden Vineyards, I now turn to the estate's winemaking and wines. The Jim Law overarching winemaking philosophy, as I see it, is "do no harm." Jim feels strongly that wine is made in the vineyard and his minimalist winemaking approach is designed to reveal the qualities which have been bestowed to the fruit by the terroir.

The Linden Vineyard style for its white wines "center around a refreshing minerality" with the weight of the wine coming from "the vineyard (sap) rather than the winemaking (alcohol, oak, lees)." Red wines are blends of Bordeaux varieties, reflecting Jim's view that "blending produces the most balanced and interesting wines." The table below captures the architecture of the Linden Vineyard product offerings.

Boisseau Red Petit Verdot Claret

The holy grail in the provision of single-vineyard wines is to best display the characteristics of the terroir in which the fruit was grown. But it is Jim's view that only the highest quality fruit is capable of being terroir-expressive. Any fruit that is incapable of representing its terroir is declassified into the Claret.

The Linden Vineyard white and red winemaking processes are detailed in the charts below.



Working the sorting table


After our discussion with Jim, Frank and I returned to the Tasting Room to taste some of the winery's current releases.


The 2016 Riesling showed sweet fruit but a lack of concentration. The 2016 Sauvignon Blanc is 85% Sauvignon Blanc, 15% Semillon, all from the Hardscrabble Vineyard. This wine showed lime, lime rind, and tropical fruits on the nose. Bright, with some bitterness, salinity, and spiciness on the palate. Drying minerality.

The 2016 Rosé is a blend of Bordeaux varietals (35% Cabernet Sauvignon, 35% Cabernet Franc, 25% Merlot, and 5% Petit Verdot) from the Hardscrabble (55%), Boisseau (40%), and Avenius (5%) Vineyards. A nice mineral nose with a note of spiciness and citrus. Bright and persistent.

The 2014 Claret is a blend of Bordeaux varietals (44% Cabernet Sauvignon, 20% Cabernet Franc, 34% Merlot, and 3% Petit Verdot) from the Hardscrabble (70%), Boisseau (15%), and Avenius (15%) Vineyards. Red fruit with some VA and green bean. Nice, light, easy drinking wine with bright red fruit.

The 2013 Petit Verdot had a smoky plum note and bright acidity but was somewhat disaggregated. The 2015 exhibited spice, darker fruit, a rich, smooth mouthfeel with good acid levels. Rich, mineral finish. Delicious.

*************************************************************************************************
During the course of our earlier conversation with Jim, Frank had asked which of the Linden Vineyard vintages were his favorites. For the whites, he said, 2009, 2013, and 2015 had been the best vintages. For the reds, 2009, 2010, 2013, 2015, and 2016. I look forward to going back to Linden Vineyards at sometime in the future to taste some of the older vintages in order to determine how these wines handle the passage of time.

Linden Vineyards (Linden, Virginia): Rebalancing for A-Class wines

I first visited Linden Vineyards about 5 or so years ago with the Lenn Thompson Taste Camp group and came away impressed with what I saw and heard. The size of the group did not allow the capture of detailed enough information so I did not report on the visit at that time.

Shortly after that visit, I had the good fortune to interview Dr. Bruce Zoecklein (at that time Professor of Enology at Virginia Tech and head of the Wine/Enology - Grape Chemistry Group; formerly Virginia State Enologist) and sought his impression of Jim Law and Linden Vineyards. Dr. Zoecklein saw Jim as having quite a unique situation vis a vis other Virginia winemakers:
  • Jim had dealt with estate fruit for over 25 years and had gained an empirical understanding of what works and what does not
  • Jim is great at making observations and banking them
  • Wine quality factors are in the vineyard and Jim is a great student of viticulture.
Coming from Dr. Zoecklein, this was very high praise indeed and further added to my resolve to revisit Linden for a more detailed data collection effort. I got my chance to do so when Frank Morgan (drinkwhatyoulike.com) arranged for us to visit to the estate on September 22nd of this year.

Linden Vineyards is situated on the outskirts of the town of Linden in Virginia's Blue Ridge Mountains. The red dot on the map below positions the estate within the context of the state and the broader region.

Red tag indicates location of Linden Vineyards
We went directly to the tasting room upon arrival and alerted staff as to our presence. The Tasting Room Attendant said that Jim was on the crush pad but had left word that he should be alerted when Frank arrived. Jim came upstairs soon after and welcomed us to the estate. After an exchange of pleasantries, Jim invited us to join him downstairs. He was in the middle of pressing some Chardonnay but could converse with us while monitoring the process.

Once on the crush pad we saw two presses being operated jointly by Shari Avenius, Linden Vineyards General Manager, and Jonathan Weber, the winemaker. We had the opportunity to observe the collegial manner in which the trio worked but there was no mistaking who had the final word.

Before addressing the Linden environment, Jim discussed making wine in the Virginia -- the wettest viticultural region in the world, as he sees it. Because of the rainfall volumes, landscape form and soil composition are major determinants of wine quality. In comparing the California and Virginia wine regions, he saw the former as having a focus on irrigation while the latter is focused on water evacuation.

Jim Law of Linden Vineyards and Frank Morgan
of Drink What You Like in an intense discussion
during our visit
Jim's guiding principles are as follows:
  • A wine's first job is to complement a meal and, as such, it should have good acidity and structure and moderate alcohol
  • Soil, site, and microclimate are more important than grape variety
  • Work hard in the vineyard to derive as much concentration as possible from the fruit
  • Non-interventionist in the cellar.
As it relates to the Linden environment, Linden Vineyards Ltd is the winery operation while Hardscrabble, Avenius, and Boisseau are the vineyard sites serving as fruit sources. Hardscrabble is the vineyard surrounding the farmstead and was the founding vineyard planted by Jim in 1985. Avenius is located 0.5 miles north of Hardscrabble and is owned by the aforementioned Shari Avenius, while Boisseau, owned by Richard Boisseau, is located 5 miles to the west in the town of Front Royal. The characteristics of these vineyards are presented in the figure below.

Looking out over one of the Hardscrabble plots from the
Farmhouse
Six acres of Hardscrabble was initially planted in 1985 but, according to Jim, he had not planted the right grapes in the right places. As he described it, he had planted C vines on A sites and gotten B wines. He is now in the final phase of a rebalancing program aimed at addressing this initial flaw. For example, some soils are too water-retentive for Cabernet Sauvignon so they are switching to Chardonnay at those sites. The application of this rebalancing philosophy -- in relation to Bordeaux cultivars -- is shown in the chart below.


Linden Vineyards has a comprehensive set of vineyard practices which are designed to ensure that the highest quality grapes make it to the harvest. The practice architecture, and associated activities, are shown in the chart below.


I will continue this discourse in a follow-up post on winemaking and the wines of Linden Vineyards.

The 18 greatest vineyards in the Barolo zone

Three of the foremost Barolo vineyard experts -- Renato Ratti, Alessandro Masnaghetti, and Antonio Galloni -- have each taken a shot at classifying the crus in the Barolo zone (I have shared the frameworks of the individual schemes in a prior post.). By taking the top-rated crus under their individual classification schemes, I have arrived at a list of the best Nebbiolo vineyards in the Barolo zone (and, hence, in the world). These 18 vineyards are shown graphically on the Barolo Zone map below and are summarized in the text following.


Brunate
According to vinous.com, Brunate had been identified as producing "wines of special character" over 500 years ago. This 25-ha cru is an inter-commune vineyard with administrative responsibility shared between the towns of Barolo and La Morra. According to ceretto.com, the soil profiles and exposure on both sides of the dividing line are essentially the same but the altitudes differ, ranging from 230 m to 400 m. The soils feature marls of S. Agata fossils with good levels of sand, especially in the higher elevations.

Cantinadamilano.it:
The lower sand levels in the soil result in aromas that are less intense but feature notes of fruit and spice such as clove, cinnamon, and nutmeg. As the wine matures, the fine structure of the terroir translates into hints of tobacco, rose and liquorice. And in great vintages, the nose has notes of truffle and tar. Alkalinity and elevated calcium levels give the final wine a touch of delicate elegance ... The Barolo of Brunate can be defined as a particularly balanced wine with an ample nose and an intense structure with good alcohol levels, as well as generous tannins and body.
According to ceretto.com, "It is one of the most representative vineyards of the commune of La Morra and has always been considered one of the points of reference of the entire appellation." Vinous cites Manuel Marchetti of Marcarini who identified Brunate wines as "austere, yet ethereal, notes of spices, mint, licorice and balsamic are all very typical." Polaner Selections was pithy: "Brunate is one of the greatest vineyards in the Barolo region ... with wines that "... are prized for their depth, power and brilliant balance..."

Cerequio
Masnaghetti (Barolo MGA) describes this MGA as extending over two virtually opposing slopes with the one facing Casa Nere being better exposed and yielding the better wines of the two.The micro-climate of the MGA is excellent, protected as it is from the cold northern winds by the La Morra hills. The loose soils, primarily silt and clay, "favors the production of structured, tannic wines that are more powerful than those from Brunate" (cantinadamilano.com).

Masnaghetti sees Cerequio as "An MGA of truly superior level, accordingly, which generally expresses a style characterized by structure and austerity but with an innate sense of power and proportion which gives this Barolo a warmer and more dynamic development on the palate compared to Brunate."

Rocche di Castiglione
Rocche di Castiglione, described by Masnaghetti as one of the most prestigious crus in all of the Barolo appellation, is located 88% in the Castiglione Falletto township and 12% in Monforte d'Alba. Its 14.36 ha (stated elsewhere in the book as 16.33 ha) has 52% devoted to vineyards (92% of vines in Castiglione Falletto and the remainder in Monforte d'Alba) and 95% of those vines growing Barolo-targeted Nebbiolo fruit. The remaining vines are targeted at Dolcetto (5%), Barbera (0.5%), and Langhe Rosso (0.5%).

Winemonger.com describes the cru thusly:
Rocche di Castiglione is one of the smallest and most renowned vineyards of the entire Barolo area. Located at an altitude of 300-350 meters above sea level, this "Cru" consists of a number of small, steep vineyard properties, and forms a long narrow strip along the side of a very steep hill with an east-southeast exposition. The lower part of this long strip of earth, which is about 1.5 km long and 60-70 meters high, sits on a cliff (rocche) that in some places drops as much as 150 meters to the Perno river at the bottom. It is characterized by large, sharp limestone blocks mixed in with the marl soil typical of the eastern side of the Barolo appellation, known as "Helvetian soils" and producing the more structured, long aging and complex wines. 
These characteristics give the wines of Rocche unique, well-defined aromas of floral and mineral compounds, softer tannins than the rest of the Helvetian zone resulting in excellent balance, and a distinctive elegance. An 'iron fist in a velvet glove."
Luca Currado, in his comments at the Galloni Rocche di Castiglione Retrospective, described Rocche wine as being like a Swiss watch in that it is very difficult to put together. First, the vineyard is steep and very difficult to work; everything has to be done by hand.  Second, vinifying Rocche is a challenging exercise. They do extended submerged cap and the tannins always take a long time to come together and then ... pop. According to Luca, you have to wait longer for the Rocche tannins to resolve than for any of his other wines.

Overlooking the Scarrone Vineyard from the Vietti winery.

Castiglione Falletto is located between Serralunga d'Alba and La Morra and its Rocche di Castiglione MGA has elements of both of these bordering communes. According to Luca, Rocche wines have the silky tannins and elegance of La Morra and the complexity, depth and power of Serralunga d'Alba.

Rocche dell'Annunziata
One of the three La Morra crus included in the top-rated-Barolo-cru categorization (the other two are Brunate and Cerequio), Rocche dell'Annunziato was part of a larger territory (Marcenasco) managed by the Benedictine monks resident in the Abbey of San Martine. According to bbrblog.com, the vineyard appears to have grown in three distinct stages:
  • Stage 1 -- The original part of the vineyard (18.8 ha) covering the lower, south- and west-facing lands below the road to Torriglione.
  • Stage 2 -- Somewhere between 1988 and 1994, it grew to encompass the southwest-facing plots (Oberto, Mascarellos, Scavino, Accomasso) just above the aforementioned road.
  • Stage 3 -- A final push to the borgata ofoiolo (Rocche Costamagna, Erbaluna). 
The vineyard lies in a hollow between the hills of San Martini and Cerequio-Brunate and, as such, experiences the sun's rays from early morning until late in the afternoon.

The Tortonian-era soils are of a clayey-calcareous nature, chalky white on the higher slopes, and siltier lower down. According to bbrblog.com, the soil is between 40% and 50% silt, a characteristic it holds in common with the lower vineyard of Cannubi Boschis. The stones present in the soils aid in drainage.

The wines from this MGA are noted for body (less noticeable than in the cases of Brunate and Cerequio), elegance (more concrete and less ethereal than is the case for Rocche di Castiglione), and complexity (Masnaghetti). Further, they are graceful and richly scented (Carlo Petrini, A Wine Atlas of the Langhe)

For Antonio Galloni, Rocche dell'Annunziata
... yields Barolos of finesse. Rocche dell'Annunziata is known for its striking, floral perfume (violets, roses), sweet spices, dark red fruit and silky tannins. These are gracious, feminine Barolos that tend to open up relatively early, but also age with grace. Rocche dell'Annunziata showcases the refined side of Barolo.
    Monprivato
    Monprivato is an "exceptionally fine vineyard on the long strip of hillside that descends from the village of Castglione Falletto to the houses of Garbelletto" (Petrini). It is "doubtlessly one of the most prestigious of the MGAs ..." (Masnaghetti).

    Monprivato is an historic vineyard, as shown by land registry archives dating to 1666. It is primarily farmed by Giuseppe Mascarello e Figli, with a small portion held by Giovanni Sordo. The crus southwest exposure, and lack of surrounding obstacles, ensures all-day access to the sun's rays.

    According to mascarello1881.com, the soil is a "clayey-silty marl with good structure, a high content of active limestone, and a well-proportioned supply of micro-elements." This soil is similar to soils of the other great vineyards on the western side of Castiglione Falletto (Petrini).

    Monprivato wines are well-structured but also offer  "elegance and intense aromas" (Petrini). Masnaghetti notes that Monprivato wines are sometimes similar to the wines of Rocche and sometimes similar to the "balanced austerity" of Villero and have delivered a long series of frequently memorable vintages.

    Monprivato1881.com:
    The soil composition and vineyard's south-westerly exposure at midday provides the Barolo wine with excellent body, a subtle bouquet, delicate tar, a lingering aftertaste, an unmistakably clear elegance, and the ability to evolve in a very positive way over time.
    A favored plot within the monopole was planted with the best clones of Michét and, in 1988, the estate began making a wine called Ca' d'Morrisio from this parcel. Both the Ca' d'Morrisio and the Monprivato cru are only made in the very best years.

    Villero
    Even though Villero is only located "a few dozen meters" from the vineyards at Rocche di Castiglione, it has a very different soil type (oddero.it). Villero's
    ... soil is tough and more compact than the Rocche because it has a higher amount of clay with limestones. The presence of clay silicates helps it retain water ... Rocche is looser and poor in nutrients.
    Both Masnaghetti and Petrini concur with this characterization. In addition, Masnaghetti sees the Villero soil as, at times, deeper and more fertile than the soils of Monprivato.

    Villero is one of the "most divided up" of the Castiglione Falletto MGAs as well as being one of the most homogenous in terms of aspect (Masnaghetti). With the exception of the lowest and highest parts of the slope -- west-facing -- the vineyard has a southwest exposure. Masnaghetti identifies the upper middle parts of the slope as being most favorably positioned while the lower portions are best suited for non-Nebbiolo reds and white grapes.

    The wines from Villero grapes are a little less elegant, with more structure, alcohol, and tannins than wines from Rocche (Petrini). Masnaghetti also describes the wines in this comparative manner seeing it as having more structure and less finesse than the wines of Monprivato. Oddero finds the wines of Villero to be rounder and juicier, with warm tones and dark fruit notes" as compared to Rocche wines which are "longer, more vertical in structure, and have more marked minerality."

    According to Selected Estates, "the presence of loam and brown clay in the soil makes Villero stand out as one of the most profound, dark-fruited crus of Barolo, with characteristic aromas of black plum, anise seeds, withered rose petals, and rhubarb."

    Francia
    Previously known as Cascina Francia, this cru was renamed Francia as part of the MGA naming process. This vineyard was purchased by the Conterno family in 1974.

    The soil is a calcareous limestone and, combined with the southwest exposure of the vineyards, yields high-quality grapes (Petrini).

    One of the southernmost of the Serralunga crus, it has relatively recently been planted to Nebbiolo. Previously it was dominated by Dolcetto, Freisa, and Barbera.

    The wines are rich in tannins and require 7 to 8 years in the cellar to reveal their true potential. According to Masnagheti, the cru yields wines that are "truly classic, rigorous but not hard, solid but not excessively concentrated." The wines have a high degree of salinity (enotecacorsi.it).

    Monfortino is made from the best grapes in the greatest year and that search begins in the vineyard with selection and vinification of "proto-Monfortino" and Francia wines.

    Vignarionda
    Vignarionda is a round-shaped (hence the name), gently sloping (300 to 350 m) vineyard located in the Serralunga d'Alba subzone.
    If you ask a resident of Serralunga to name the town's three finest vineyards, one of the trio is sure to be Vigna Rionda. It is an historic vineyard. The quality of its grapes has been celebrated for hundreds of years and the greatest names in Langhe winemaking have for many years made special efforts to acquire grapes from Vigna Rionda (Petrini).
    The vineyard's location ensures access to sunshine for most of the day while also using the Castelleto hills for protection from excessive winds.

    According to oddero.it:
    Like all soil in Serralunga, its origins date back to the Serravallian Age (sometimes called Helvetian), characterized by Lequio soil, or layers of grey marl alternating with sandstone, formed by siliceous sands that are more or less cemented between the marl layers, and calcium carbonate, iron carbonate, and inorganic residuals of vegetable and mineral organisms. Vignarionda's soil is rich in microelements like potassium, boron, manganese, and magnesium. Its active limestone content is quite high -- at 13.58%, it is the highest in the entire Barolo zone.
    The wines from the cru are "fairly tannic ... with outstanding structure and excellent aging potential" (Petrini). Masnaghetti sees the wines as "austere, severe, and sometimes unyielding, whether they be made from from the grapes of the historical nucleus ... or those grown in the western-facing sector."

    Cannubi
    Cannubi is a long, gradually sloping hill which extends northeast from the village of Barolo and is contained in its entirety within the namesake commune. According to the Marchesi di Barolo website, Cannubi hill is protected from storms and extreme weather by higher neighboring hills. Both Damilano and Marchesi di Barolo point to the uniqueness of the hill in that it sits at the convergence of the aforementioned Helvetian and Tortonian soil zones resulting in "grey-blue marls rich in magnesium and manganese carbonate that, on the surface, thanks to the air and the weathering, turn into grey-white marls" (Marchesi di Barolo).

    Chiara Boschis' Pira e Figli was the first Cannubi estate to convert to organic farming, gaining its certification in 2014 (Labor of Love). But she was not content with practicing this only in her vineyard. She became an evangelist on Cannubi such that today fully 99% of the producers on the hill are organic.

    Gabutti
    "We are not exaggerating when we say that Gabutti is the starting point of a long ribbon of vineyards along the side of the most prestigious hill in the municipality of Serralunga, and one of the most outstanding in the entire Barolo DOCG zone." (Petrini).

    The south-facing aspect, steep slope, and protection from the wind combine to render this MGA a prime location for the growth of Nebbiolo grapes. Soils are of the Lequio Formation with loose calcareous clay marls from the Langhian stage of the Miocene epoch.

    Masnaghetti sees the beating heart of the MGA as the area between Parafada and Cascina Marianot where the southern exposure compensates for the relative lack of luminosity. The style of wines from that area range from "the rugged and rather classical tannic impact of of the Cappellano wines to the rougher Barolo of Franco Boasso, whereas the eastern side of the cru offers the flowing and floral style of Giovanni Sordo's Gabutti."

    Parafada
    This vineyard is more uniform in its exposure than Gabutti or Lazzarito and can be seen as a bridge between those two MGAs (Masnaghetti). The Delizia plot, primarily owned by Fontanafredda, produces very high-quality wines from its "fairly shallow white clay and limestone marl" soils (Petrini).

    The wines from Parafada are "less voluminous than Lazzarito and more refined than Gabutti" and are endowed with the vigor and presence on palate and nose that is the hallmark of a first-order wine (Masnaghetti).

    Lazzarito
    A large vineyard in Serralunga d'Alba whose name can probably be traced back to an ancient hospital for Black Plague victims on the property. According to Masnaghetti, the vineyard can be divided into two parts:
    • Eastern slope -- smaller in size and less well known
    • Western slope -- can be further divided into the La Delizia and Lazzarito amphitheaters
    Masnaghetti also references a < 2 ha plot lower down on the slope called Lazzairasco, an area with favorable south to southeast exposure and with excellent quality potential. Santa Caterina, on the southern boundary, like Lazzairasco, was absorbed by Lazzarito in 1990 during the township-mapping process.

    A significant portion of the vineyard is owned by Fontanafredda but Ettore Germano and Vietti also farm plots there. Sergio Germano (Ettore Germano) and Luca Currado (Vietti) were both interviewed about the vineyard on a Vinous video. Sergio sees the main characteristics of the vineyard as the elegance and finesse that it imparts to the wine. The wine is strong with lean-textured tannins and a lengthy finish. The soil has a high limestone concentration but also has some beach-like sand which gives a "slim texture" to the wine.

    Marenca
    The pronounced amphitheater of the Marenca vineyard provides the vines with excellent exposure to sunlight. The soil is a calcareous clay.

    There is only one labeled wine originating from the vineyard -- produced by Luigi Pira -- but it is of high quality "with a structure which is among the deepest and most complex of the entire township" (Masnaghetti).

    Rivette
    The vineyard sits at the foot of the inhabited area of Serralunga d'Alba and is immediately recognizable by the vine rows running vertically up the hillside rather than horizontally across the hill, as is the case for neighboring  vineyards.

    According to Petrini, Rivette has always been regarded as an excellent location for growing Nebbiolo. The soil is a loosely packed marl and limestone mix and the quality of the grape are "beyond dispute." Petrini's description of the MGA is a little at odds with that of Masnaghetti's who states that, with the exception of a few small plots owned by Pira and Massolino, the remainder of the vineyard -- owned by Gaja -- is used for white grape production.

    Brea
    Only one of the top-level vineyards covered in this series that is not represented in A Wine Atlas of the Langhe. Also called Ca'Mia and, according to Masnaghetti, had had some repute in past times but had fallen out of favor until resurrected by the Brovias in the 1990s. Masnaghetti describes the wines as having classic and austere elegance.

    Falletto
    This cru is synonymous with the name Bruno Giacosa, one of the most heralded of the Barolo and Barbaresco producers. When the cru and winemaking are combined, the results are Barolos that are austere, balanced, and in possession of an "unimitable classicism."

    Giacosa made his wines with purchased fruit until he bought the "majestic" Falletto vineyard in 1982. This vineyard, it is widely agreed, became the source of one of his greatest Barolos.

    The Giacosa formula for great vineyards is (i) high hill country positioning, (ii) south to southwest sun exposure, and (iii) amphitheatre-like vineyards; Falletto fits this profile almost perfectly.

    The Giacosa wines from this vineyard are labeled Falletto (white label) and Rocche del Falletto (from four south-facing plots on the upper slopes of the vineyard.

    Ginestra
    The map below shows the Cru Ginestra divided into four subzones (indicated by names in capital letters): Ginestra, Gavarini, Grassi, and Pajana.

    Ginestra cru, sub-crus (all caps), and vineyards
    In discussing this cru, Masnaghetti focuses on the ridge of the Ginestra subzone. A tongue of hillside, he says, "as majestic as it is elegant and from which, over the past thirty years, have issued forth some of the wines which have made the story of the Barolo appellation."

    The other subzones, according to Masnaghetti, "have always enjoyed their own separate identity" and "their historic and viticultural value, particularly in the case of Gavarini, should have assured them of an official delimitation of their own." This separateness is illustrated in A Wine Atlas of the Langhe wherein Petrini treats each of these subzones as individual crus.

    Gavarini
    This zone is almost exclusively owned by the Grasso family and is the source of the grapes for the estate's Gavarini Chinieri wine. This vineyard is 3 ha (7.41 acres) in size, convex, has good ventilation, and its soil is comprised of clay, limestone, and eroded sandstone. At a recent tasting at the estate, I found that the 2013 Barolo Gavarini Chinieri had a beautiful sandalwood nose with sweet florality, rose petals, nut, spice, and tar. On the palate, tar and earthy red fruits. Medium weight.

    Like the Chinieri vineyard, Runcot is located within the Gavarini sub-cru. This 18-ha (44.48-acre) vineyard was replanted in 1989 - 1990 at 4500 vines/ha with the first vintage produced in 1997. This wine is only produced in great vintages. 

    In the years when Runcot is not produced, the fruit is declassified to Langhe Nebbiolo. The Langhe Nebbiolo is vinified in stainless steel and is sold in the spring following vinification. The 2016 Langhe Nebbiolo was floral with sweet strawberry, cherries and tar on the palate. Aggressive tannins. Pure Nebbiolo.

    Grassi
    The plots with favorable exposition cluster around the center of the cru (Masnaghetti). The soil is more compact and less sandy, especially in the lower parts of the vineyard.

    Ginestra
    As described by Masnaghetti:
    The highest part has given us Ciabot Mentin Ginestra, powerful, and, at times, brooding and somber while in the lower parts we find, respectively, the elegant Casa Maté and Sori Ginestra, a type of ideal blend of the two previously cited wines. In the final part, characterized by a deep indentation, we find the vineyards of the Barolo of Paolo Conterno and of Conterno Fantino's Vigna del Gris, more classic and fresher the first, more rugged the second.
    Casa Maté is located within an amphitheatre, is south-facing, ripens earlier, and has clay and limestone soils. We tasted a number of vintages of this single-vineyard wine during our visit to the estate: 2013, 2007, and 2004. The 2013 showed spice, tar, baking spices, and an earthiness. Depth and structure. Great mouthfeel. The 2007 showed obvious development. Tar, waxiness, honeyed fruit, mint, eucalyptus, herbs, florality, and curry. Tar on the palate along with a long, caressing finish. The 2004 also showed curry and tar on the nose. Great weight on the palate. Beautifully balanced.

    Pajana
    This subzone is located at the forking of the Ginestra ridge. Its Barolo, made famous by Clerico, is forceful but less-complex than the Barolos of Ginestra (Petrini).

    Ornato
    With the exception of two small plots farmed by Palladino, the Ornato cru is owned by Pio Cesare. According to Masnaghetti, the cru is characterized by "steep slopes, excellent soils, and a full southern exposure." The 6.59-ha (16.28-acre) cru is planted only to Nebbiolo on soils that are mainly limestone and clay with a small portion of sandstone (Pio Cesare). The Ornato Barolo produced by Pio Cesare is sourced from three plots in the vineyard.

    Pio Cesare stipulates that the wines of the cru have big structure and tannins as well as long aging potential. The fruit from the Ornato vineyard is "exceptionally ripe and constantly produces bright, robust, focused wines with incredible complexity and length" (Rogers and Company).

    Carlo Petrini: "Barolo Ornato is known for its intense aromas, which over time acquire a distinct note of tar. Their structure is unmistakably that of a wine from Serralunga, which means that they have excellent aging prospects."

    Masnaghetti observes that the wines "express power, fleshiness, and -- after a certain aging period -- a good dose of elegance as well."

    I conclude with a compilation of the key characteristics of each of the mentioned vineyards arranged by degree of agreement among the three experts.

    Virginia wine: The physical environment

    I recently visited a number of Virginia wineries with Frank Morgan (Drink What You Like) and will be reporting on those visits in upcoming posts. Prior to those posts, however, I will attempt to familiarize readers with the physical environment within which the region's grape growers operate. I will begin with the landscape, given its role in shaping the state's climate.

    Virginia Landscape
    With the exception of alluvium and wind-blown soils, an area's soil is derivative of its underlying rocks. As shown in the charts below, Virginia, as a result of long-term tectonic, orogenic, erosional, sedimentary, and intrusional activity, is divided into five major geologic zones. The first chart describes the formation and characteristics of each zone while the latter identifies the rock types included in each zone as well as its period of deposition/intrusion.

    Virginia Climate
    Climate, according to Dr. Tony Wolf (Lecturer and Viticulturist, Virginia Tech) and John D. Boyer, is the average course of weather in a region over an extended period as measured by temperature, precipitation, and wind speed, among other variables (Vineyard Site Selection, Virginia Cooperative Extension).  Weather is itself defined as the state of the atmosphere at a specific point in time using the same variables as referenced in the climate definition above.  The climate of a grape-growing region will determine, to a large extent -- and all things being equal -- both the grape varieties that can be grown and the styles of wine that can be produced. The climatic requirements for successful viticulture include: a growing season long enough to mature both the fruit and vegetative aspects of the plant; production of sufficient carbohydrates to ripen the fruit as well as to maintain future productive potential; and an adequate supply of water.

    Virginia's climate is officially described as humid subtropical but, in reality, it has one of the most complex climates in the US. This complexity is reflected by the fact that the state is divided into five climate zones (The figure below actually shows six zones because it breaks Piedmont into eastern and western portions).

    VA climate zones: 1 - Tidewater; 2 and 3 - Piedmont;
    4 - Northern; 5 - Central Mountain; and 6 - Southwestern Mountain
     (Source: http://virginiaplaces.org/climate/)
    According to the University of Virginia Climatology Office, "Virginia's climate results from global-scale weather patterns that are modified by the diverse landscape of the Commonwealth." The following two charts show the manner in which these global-scale weather patterns are modified within the Commonwealth. The first chart shows two temperature modification events. The first is associated with winter storms. These storms work from west to east across the state and turn northeast when they encounter the Gulf Stream. Moisture-laden air from these storms are then blown onto land from the east and northeast, with most of the rain ending up on the eastern slopes and foothills of the Blue Ridge Mountains.

    The second event is the classic rain-shadow effect where winds from the west encounter the Appalachian Mountains and dumps moisture on the western slopes of that range as they climb while eastern winds encounter the Blue Ridge Mountains and act accordingly. As shown in the figure, the regions between those mountains are the driest in the state.

    Derived from climate.virginia.edu
    The water falling on the state is drained off by an extensive riverine system. The workings of this third climate modifier is shown in the figure below.

    Acording to Jim Law of Linden Vineyards, Virginia is one of the wettest viticultural regions on the planet. The chart below shows the trend of VA average annual precipitation between 1895 and 2010 and the trend is towards increasing levels statewide. The table below the chart shows the distribution of that precipitation by climate zone.

    Trend of VA average annual precipitation, 1895 - 2010
    (Source: http://virginiaplaces.org/climate/)

    Climate Zone Annual Average Rainfall (inches) January Average Temperature (F) July Average Temperature (F)
    Tidewater
    41.32
    35 - 48 71 - 85
    Piedmont
    43.37
    27 - 47 68 - 88
    Northern Virginia
    38.29
    19 - 42 61 - 86
    Western Mountain
    40.74
    27 - 45 65 - 87
    Southwestern Mountain
    47.33
    24 - 44 60 - 85

    As shown in the table above, the average annual rainfall in Virginia ranges between 38.29 and 47.33 inches per year. Contrast this with Napa which receives an average of 20.39 inches, less than half of the rain that Virginia receives. The problem with that much water is that it requires the right type of soil and slope in order to allow proper drainage of the vineyard. Some grape varieties do not like wet soils while too much water does not allow for stressing of the vines, a key requirement in growing high-quality red wine grapes.

    In a May 2012 interview with Dr. Bruce Zoecklein, then Professor of Enology at Virginia Tech (and former State Enologist), he told me that Virginia winemakers had to deal with late frosts, drought, high humidity, and tropical storms in the fall and that they needed to continue working to understand these phenomena and then to incorporate their learnings into their viticultural processes.

    Virginia Wine Regions
    The Virginia Wine Board Marketing Office (VWBMO) provides a map which divides the state into various wine regions and then indicated American Viticultural Areas (AVAs) within those regions. I used such a map as the basis for a graphical presentation of the characteristics of each region (see below).


    During the compilation of chart, I became curious as to the genesis of the wine region map and pursued answers along a number of paths. Frank Morgan was finally able to get me a response from Annette Ringwood Boyd of VWBMO which stated that the regions were determined by Virginia Tourism and, when VWBMO started 10 years ago, they "used these so that there would be continuity in how people were talking about Virginia regionally." According to Annette:
    As they have added regions, we have mimicked them to continue that seamless presentation of Virginia. One of the strong arguments in support of this strategy is that 60% or more of VA wineries are not in AVAs ... In addition, in 2009 or 2010 we added Virginia AVAs to begin to add wine specific regions to our map. To date this is still imperfect, but long term, this is how we would like for the regions of Virginia to be defined. Until the AVAs are more inclusive, we will use the VTC regions of Virginia.
    In other words, the Virginia wine regions, as currently configured, is a marketing contrivance with no undergirding viticultural rationale. While this will work for a tourist-based wine economy, it will force us to continue to look to individual wineries to determine high-quality wines because comparisons within and across regions (outside of the AVAs) are essentially meaningless.

    Crossflow filtration and the Barboursville Vineyards (Barboursville, VA) experience: A conversation with Luca Paschina, General Manager-Winemaker

    Winemakers are largely divided between those who filter their wines and those who do not. Those who eschew filtration are concerned that the practice can strip out aroma and flavor molecules, thus rendering the finished product less-than-optimal. In his argument against traditional filtration, Clark Smith, author of postmodern winemaking, states thusly:
    The focus of postmodern philosophy is the creation and preservation of beneficial macromolecular structure. This structure manifests in wine as colloidal particles sometimes nearly as large as a bacterial cell. The benefits of good structure -- profundity, aromatic integration, and graceful longevity -- appear to be lost in sterile filtration, despite the fact that no tannin material may be retained by the filter. While this lack of residue has convinced some of my colleagues that filtration cannot be harmful to wine structure, I do not concur. My hypothesis is that the action of tight filtration somehow disrupts rather than removes structure.
    In a January 2003 article, Smith  described a class of filtration systems which he called the Tangential Flow Family of Filtration. This family is shown in the table below, classified based on the molecular weight of particles that pass through the pores.

    According to Smith, the idea of tangential flow filters developed in the 1960s. One of the major problems with sterile filtration is the fouling of the membrane which occurs when tight pore sizes are used. This fouling prevents the passage of material through the pores. The effective limit of traditional filtration is 0.1µ. Tangential flow filters use the scrubbing action of the flow across the surface of the membrane to keep it clean thus allowing the utilization of ever-smaller pore sizes.

    All of the systems mentioned in the table employ the strategy of pumping the wine across the membrane at high velocity. As the wine flows across the membrane it continually scrubs the surface, removing fouling material. The majority of the feed stream does not pass through the filter but is retained upstream and returned to the tank. This stream, called the retentate, contains all of the high-molecular-weight components. The low-molecular-weight material that passes through the filter is called the permeate. A comparison of traditional (dead-end) versus tangential filtration is shown in the figure below.

    The Holy Grail of tangential filtrations, according to Smith, "is to be able to clarify wine without harming its structure, and crossflow clarification ... continues to gain steam." In his opinion, the technology works well for unstructured whites, "where a little tannin and color stripping is a good thing, but can prove disastrous for structured reds."

    I now turn to my discussion of crossflow with Luca Paschina of Barboursville, a follow-up on a wide-ranging discussion of the estate and its wines. As stated above, Smith has some problem with crossflow filtration and I wanted to see whether his views were being validated at Barboursville.

    Luca first became aware of crossflow technology around the year 2000 and was immediately impressed. Barboursville first employed the Bucher-produced system in 2004 in an attempt to clarify its wines in a one-step process. Prior to its implementation of crossflow, the winery was going through at least two levels of filtration and wasting a lot of time and product. The process employed for filtration prior to the acquisition of the crossflow technology was diatomaceous earth (DE) and different levels of pad porosity, staples of the dead-end approach. The issues associated with this approach are catalogued below.


    In addition to the one-and-done aspect of crossflow, Barboursville also uses it to remove yeast and bacteria in white wines (thus avoiding the potential of malolactic or yeast fermentation of residual sugar in the bottle) and in reds to avoid Brett bloom in the bottle.

    The technology is used on white wines after stainless steel aging on lees, allowing for filtering of the fine lees. These wines are filtered the day before bottling. Red wines are transferred from barrels to tank and then filtered the day after (or later if necessary). Crossflow filtration is applied to every wine once per week between mid-January and late July.

    Barboursville purchased its crossflow equipment and paid it off over 5 years. The technology is easy to use but requires an operator with an attention to detail and the ability to follow procedures. The winery is very satisfied with the equipment and the associated process. Staff has adapted positively to the implementation of the product.

    In terms of additional advantages, Luca can time his bottling schedule with more versatility (such as filtering today and bottling tomorrow), with no surprises arising from filtration difficulties.

    In closing, Luca mentioned that he had initially been skeptical of the product but after seeing how the wines were aging gracefully, he is now a firm believer in the technology.

    My conclusion: Luca is using crossflow in an effective and traditional manner (that is, replacement for a DE system) and is currently very satisfied. None of the Clark Smith concerns are evident here.
