Mapping the sparkling wines of Italy

A little over seven months ago, I set out on a journey to develop a map of the sparkling wines of Italy. Fairly early in the process I realized that I would have to undertake the task on a region-by-region basis due to the wealth and diversity of available data. I have completed that effort and thumbnails of each region's map is included in the chart below.


The data show 137 DOC-level sparkling wines and 16 at the DOCG level. Within each of the appellations, one or more labels are allowed and the wines can be specified Metodo Classico, Charmat, or either. International varieties are the most broadly distributed across the regions with Chardonnay, Pinot Bianco, Pinot Nero, and Pinot Grigio each being used liberally. This highlights the fact that producers largely utilize regional indigenous varieties in making sparkling wines in their individual regions.Wines are specified either as blends or varietals.

Of the large number of allowed wines, a few are more widely recognized than the large majority. I provide a more detailed view of these noteworthy wines in the text below.

Prosecco DOCG 
There are two separate Prosecco DOCG zones, both falling within the borders of the province of Treviso. The first, and having the greatest repute, is Prosecco di Conegliano-Valdobbiadene. This zone is approximately 50 km from Venice and 100 km from the Dolomites. It runs east to west from the plains to the foot of the Alps and incorporates the 15 hill communities that lie between Conegliano and Valdiobbadene. Approximately 6100 ha of vineyards are deployed on south-facing slopes that range between 50- and 500-meters high.

An area within the municipality of Valdiobbadene called Cartizze is considered the region's cru. This 106-ha area has a mild microclimate and a varied soil to include moraine, sandstone, and clay components. The vineyards are positioned on south-facing slopes and have excellent drainage.

The second DOCG zone is Colli Asolani/Asolo and is located in the Montello e Colli Asolani wine region. It encompasses a 5-mile-long ridge of gently rolling hills running between the towns of Cornuda and Asolo. The best vineyards are found on south-facing slopes where the gentle gradients and loose soil combine for excellent drainage and optimal sunlight exposure.

Prosecco DOC
The Prosecco DOC was first awarded in 1969 and was restricted to wines produced in the Conegliano-Valdiobbadene region.  Growers felt that the brand was under attack by "imitators" using just the grape variety and moved to isolate those competitors by changing both the rules and the venue of the game.  Prosecco growers agitated for, and gained regulatory acceptance of: (i) extension of the Prosecco DOC to cover all of Friuli-Venezia-Giulia and approximately two-thirds of Veneto; (ii) promotion of the original Prosecco DOC to DOCG status; (iii) changing the name of the source grape from Prosecco to Glera; and (iv) restricting the use of the name Prosecco only to Glera sparkling wines produced within the delimited zones.  The growers felt that these actions would serve to protect their territory, the brand, and the quality of Prosecco.  The regulations authorizing these actions came into law in 2009.

The Grape(s)
Prosecco is primarily made from the Glera (formerly Prosecco; also known as Prosecco Bianco and Proseko Sciprina) grape variety, a native of northeast Italy which has been used to produce wines since Roman times.  This late-ripening, thick-skinned variety has greenish-yellow berries which evolve to a yellow-gold color as the grapes ripen.  The grapes are high in acid and have a white peach aromatic profile, qualities which render them eminently suitable for the production of sparkling wines.

Glera is primarily used in the production of fizzy and sparkling wines but there are a few examples of still Glera wines around.  In addition to Glera, Prosecco wines can contain as much as 15% of other grape varieties.  The most oft-used supplements are Verdiso, Branchetta, Perera, Glera Lunga, Pinot Bianco, Pinot Noir, Pinot Grigio, and Chardonnay.

Prosecco DOC Production Area
Prosecco DOC wines are authorized for production in Friuli-Venezia-Giulia and Veneto (provinces of Treviso, Belluna, Padova, Venezia, and Vicenzia).  Within the broader Prosecco DOC, there are two sub-zones: DOC Treviso Prosecco and Prosecco di Trieste. These sub-zones cover Prosecco made within these two provinces and wines made therein can so indicate on their labels.  Prosecco wines made in other provinces cannot carry the province name on the labels.

Prosecco Rosé
This is a new addition to the lineup and is viewed as having the potential to provide a significant sales boost to the Consorzio members who have been suffering the effects of the Coronavirus pandemic. The requirements for the new entrant are as follows:
  • Glera base blended with 10 - 15% Pinot Nero
  • Max yields 18 tons/ha for Glera and 13.5 tons/ha for Pinot Nero
  • from Brut Nature to Extra Dry
  • Prise de mousse must happen in vat according to the Charmat Method for a minimum of 60 days
  • Commercialization allowed fro January 1st following harvest
  • Labels must be vintage-dated (millesimato) with a minimum of 85% of the fruit coming form the stated vintage.
Asti DOCG
Asti DOCG is by far the largest sparkling wine appellation in Piemonte with 9700 ha under vine in 52 municipalities stretching across the provinces of Alessandria, Asti, and Cuneo. Most Asti production is via the Charmat method but, as the region's sparkling-wine map shows, there is a designation for Asti Metodo Classico. The Moscato Bianco grape is used as the raw material for the Asti wine.


Alta Langa DOCG
Alta Langa -- DOC in 2002, DOCG in 2011 -- is the new kid on the sparkling-wine block but the combination of its terroir, traditional Champagne varieties, traditional production method, skilled growers, and savvy producers bode well for the future.

The Alta Langa DOCG is spread over 142 communes in the provinces of Alessandria, Asti, and Cuneo. Given the geographic scope of the region, one encounters a variety of climates, exposures, elevations and soil types. In general, the soil is a mildly fertile calcareous clay marl.

Vineyards are required to be planted at 250 m and above on the region's steep, terraced hillsides. Allowed varieties are Pinot Noir and Chardonnay and other non-aromatic grapes. Planting density is a minimum of 4000 vines/ha with the vines trained using the low espalier system and pruned traditional Guyot and spurred cordon. The maximum allowed yield is 11,000 kg/ha.

The Alta Langa producers -- 27 currently -- do not grow enough fruit to meet their needs but that gap is bridged with fruit from 80 growers who own their land and are guaranteed producer-payment for their grapes and labor.

Franciacorta DOCG
Franciacorta (the name means either "little France" or "tax-free zone," depending on the publication consulted) is located in the "gentle" hills in the area of Brescia and is bounded thusly: to the east by rocky hills; to the west by the Oglio River; to the north by Lake Iseo and the foothills of Alpi Retiche; and to the south by the Brescia-Bergamo Highway.  The region lies in an amphitheater which was carved out by a falling glacier and encompasses all or part of 19 Brescian municipalities.   The zone is approximately 18,000 hectares in size with 2665 hectares under vine.

Source: Franciacorta.net

Franciacorta is mild in the winter and hot in the summer.  The climate is moderated by winds blowing in off Lakes Iseo and Garde which protect the region from the autumnal and hibernial fogs that threaten from the Brescian plains.  Rainfall in the region is concentrated in the spring and fall.

Thanks to exhaustive zoning studies conducted in the region in the late 1990s by the University of Milan, a very clear picture of soil differentials -- and the differing contributions of each type to the finished product -- has been established.  The figure below shows that the combination of landscape units (formations by geologic era) and soil types results in six distinct regional terroirs.  The figure illustrates that the soil, vegetative productive, qualitative, and organoleptic characteristics of each terroir has also been identified.  The details of those characteristics are contained in the table following.

Characteristics of Franciacorta Terroirs. Derived from Franciacorta: un vino, una terra, p. 28-33

The sparkling wine is produced under the DOCG classification from Chardonnay, Pinot Noir, and Pinot Bianco grapes. The wines are produced using the classic method and, depending on the terroir in which it was grown, or the blend of terroirs, will exhibit some subset of the organoleptic qualities indicated in the last column of the table above. Wines are labeled in terms of sweetness much the same as is the practice for Champagne.

A fourth variety -- Erbamat -- is emerging as potential aide in the battle against the ripeness and climate effects of the region. Erbamat is a high-acid, late-ripening white grape that is native to the region and with a history that stretches back to circa 1500. The cultivar had slipped into obscurity until a recent study by a university professor highlighted its characteristics. Its primary characteristics are as follows (Aldo Fiordelli, Decanter, 3/21/17):
  • Pale straw color with greenish tinge
  • Thin skin
  • Compact bunches
  • Late ripening (20 - 30 days after other varieties)
  • Higher levels of malic acid (produces lean-bodied, high-acid wines)
  • Low sugar production (low alcohol wines).
The thin skin and tight bunches render the grapes subject to disease pressure but that risk is more than offset by the freshness, white florality, and chalky minerality which this wine brings to the blend. The variety is allowed in all of the Franciacorta styles with the exception of Satén.

The most respected producers in the region are Bellavista, Berlucchi, Ca' del Bosco, Cavalleri, Facoli, and Monte Rossa.

Oltrepò Pavese Metodo Classico DOCG
Oltrepò Pavese's 13,500 ha of vineyards makes it one of Italy's largest appellations while its 3000 ha of Pinot Noir vines is easily the largest planting of that variety in Italy. The appellation covers 42 municipalities in the Apennine foothills on the south bank of the Po River across from Pavia; foothills comprised of marine sedimentary rock with significant clay content.

Winters are dry and temperature fluctuation is significant due to ascending air current on the slopes.

Pinor Noir is the dominant variety for sparkling wine production. The first sparkling wine from this variety was made by Count Augusto Giorgi di Vistarino in 1865 and the family still produces some of the best spumante in the region today.

Trento DOC
Trento DOC is the specific appellation for sparkling wine produced in the Trento portion of Trento-Alto Adige. As is the case in Alto Adige, the wine is made using the Metodo Classico.

Trentino terroir is similar to that of Alto Adige even though it is 150 m lower down the valley. The DOC stretches for 800 ha over 74 municipalities with elevations ranging between 100 and 800 m.

Its climate is modified by the peaks and ridges which protect the region from the elements. A cool breeze from the mountains minimizes the exposure to rot and fungal diseases. Two winds blow on the area north of Lake Garda from March to September: a north-to-south morning wind and a south-to-north afternoon wind.

The two major growing areas are Val di Cembra and Valle dei Laghi with the former being narrower, with more volcanic soil, and showing greater effects of elevation. The latter is closer to Lake Garda and shows more of a Mediterranean climate. The soil is a stony limestone in the upper reaches with moraine deposits lower down.

Chardonnay and Pinot Noir  dominate the vineyards. Chardonnay does better at higher altitudes with sun exposure (provides the backbone) while Pinot Noir enjoys lower, less sunny altitudes (imparts body). Producers source grapes from multiple areas and will blend wines from warmer and cooler sites.

According to Kerin O'Keefe, the sparkling wines of this region show "pronounced aromatics, elegance, and bright acidity." Two producers that she recommends are Ferrari (2010 Perlé Nero Extra Brut Riserva) and Rotari (2011 Flavio Brut Riserva).

Approximately 7,500,000 bottles of sparkling wine are produced in this region annually.

Lissini Durello DOC
This sparkling-wine-only appellation covers the high valleys of the Lissini Mountains between the provinces of Verona and Vicenza. The volcanic slopes provide the high hillside vineyards exposure, ventilation, and diurnal temperature variation, all of which contribute freshness and aromatic qualities to the sparkling wine.

The variety is Durella, indigenous to these mountains since the Middle Ages. The grapes are golden-hued with thick skins and acidulous flavor. Because of its high acidity the Durella destined for sparkling wine is picked at full maturity.

Writing in Wine Enthusiast (Metodo Classico, Your Next Italian Sparkling Wine (That Isn't Prosecco)), Kerin O'Keefe describes these sparkling wines as boasting "... tension, energy, and finesse." O'Keefe also points out that an upcoming regulatory modification will have the name Lessini Durello used exclusively for Charmat sparklers while the Metodo Classico versions will be called Monte Lessini. Her wine recommendations are:
  • Coret Moschina 2012 Riserva 60 Mesi
  • Sandro de Bruno NV 36 Mesi
  • Fattori 2012 Ronca Non Dosato 60 Mesi Metodo Classico.
Vigneti della Serenissima DOC
This appellation covers the hilly and foothill areas of the provinces of Belluno, Treviso, Padua, Vicenza, and Verona between the Alps in the north and the Po Valley in the south. The climate is conducive to gradual ripening of grapes. Sparkling wines are produced using the classical method.

Abissi Sparkling Wine
Bisson Winery in Liguria has been aging its Metodo Classico wines in 60 meters of water off the coast of Portofino since 2005. The wines -- there are three of them: Spumante Classico, Spumante Riserva, and Spumante Rosé -- are fermented traditionally to produce the base wines and are then bottled and lowered into the sea in July so that the second fermentation can be completed in the anaerobic conditions below the surface of the water.

The Spumante Classico and Riserva are blends of Bianchetto Genovese, Vermentino, and a third cultivar called Cimixià. The Rosé is a blend of Granaccia and Ciliegiolo.

The innovative method of aging is the brainchild of Pierluigi Lugano, the enterprise's winemaker. "When the wine bottles are picked up, they are enriched with incrustations (sic), seaweeds (and sometimes shellfishes, too) ... For health and sanitary reasons, bottles are then dried and wrapped under a protective, clear film, which also serves the purpose of preserving the natural ornament made by the sea,"

Lambrusco
"The main Emilia wine is undoubtedly Lambrusco, the fizzy and sometimes sparkling, jovial red wine from grapes grown on high trellised vines in five DOC zones in Modena and Reggio Emilio." The map below shows the Lambrusco production area within Emilia-Romagna.

Lambrusco production area 
(Source:http://emilialambrusco.com/en/lambrusco/)

Lambrusco first came to prominence as "cheap, cheerful and fizzy plonk served with ice cubes ... cloyingly sweet versions that flooded U.S. shelves in the 1970s and '80s" (O'Keefe). In an article asking readers to take a second look at the wine, Karen O'Keefe sees that "a number of producers now make distinct, slightly sparkling Lambruscos that belong on every wine lover's radar."

As shown in the sparkling wines maps, there are three specific Lambrusco DOCs (Sorbara, Grasparossa di Castelvetro, and Salamino di Santa Croce) and two other DOCs (Modena and Reggiano) which also produce Lambrusco sparkling wines.

Lambrusco di Sorbara is generally lightly colored, fragrant, and in possession of vibrant acidity. The grapes are thin-skinned, with very little pigment, and the bunches have berries of varying sizes. Grapes for this wine excel in the sandy, fertile plains between the Secchia and Panarao rivers. O'Keefe sees this wine as the most-refined of the Lambrusco category.

Lambrusco Grasparossa di Castelvetro is made from a "thick-skinned, late-ripening, darkly hued" grape that is definitively more tannic than the Sorbara variety. This variety does well in clay and silt soils.

Lambrusco Salamino di Santa Croce is the most planted of the Lambrusco grapes and is often blended with other Lambrusco wines to take advantage of its color and and acidity. The soils in the growing area are similar to the soils in the Sorbara region but some grapes are also grown in the clay and rocky soils close to the Reggio Emilia foothills.

Novobolle
Sparkling wine production in the province of Romagna peaked at the beginning of the 20th Century and then declined somewhat. In order to recapture this past glory the Romagna Consorzio has introduced a new trademark of Romagna Spumante DOC that every producer in the region can utilize if specified conditions are followed. The name of the new wine is Novebolle (nine bubbles) with Nove (nine) referring both the the nine hills of Romagna as well as the period (1900s) in which sparkling wine had flourished in the region.

The wine can be white or Rosé and can be made by either the Charmat or Traditional method. The composition of both wines are included in the second of the two sparkling wine maps above.

The first expression this new trademark has been captured in Bolé, a joint venture between two of the region's Coops: Caviro (the largest winery in Italy) and Terre Cevico.

This Bianco is a mix of Trebbiano and Famosa (5%) made using the classic method. Plans call for increasing production from today's 45,000 bottles to 100,000 bottles and the production of a Rosé that adheres to the Consorzio's restrictions.

Vernaccia di Serrapetrona DOCG
This wine has been described as an "idiosyncratic sparkling red wine produced from the local Vernaccia Nera." This territory was granted DOC status in 1971 and elevated to DOCG in 2003. It is one of the smallest classified zones in Italy with only 20 ha of vineyards and 5000 cases produced. Vineyards must be sited between 450 and 600 m elevation.

Other than the fact that it is a sparkling red wine, Vernaccia di Serrapetrona is also unique in its production method: three fermentations. The first fermentation involves up to 60% of the handpicked grapes. The remaining 40% is dried on straw mats and added to the wine in the following January for the second fermentation. After resting for a few months, the wine is placed into pressurized containers where it is fermented using the Charmat method.

The result of this process is "an intensely aromatic wine displaying a raspberry red color, aromas of strawberries and cranberries, a hint of spice, firm tannins and bright acidity,"

Verdicchio dei Castelli di Jesi DOC and Verdecchio di Matelica DOC
These are the two DOCs that are the temples to Verdicchio, with the former being more revered than the latter. The sparkling wines from both regions require a minimum of 85% of the Verdicchio grape and can be made using either the Metodo Classico or Charmat methods.

The grapes for Verdicchio dei Castelli di Jesi are grown in the hilly areas around the town of Jesi, an area endowed with calcareous clay and limestone-rich soils. The area is blessed with a relatively dry maritime climate with persistent gentle onshore (morning) and offshore (afternoon) winds providing defenses against fungal diseases such as grey rot and mildew.

The Verdicchio di Matelica vineyards are located further inland in more of a continental climate but with soils akin to its compatriot. Vineyard orientation in Matelica is east-to-west, a situation unique to that DOC. A total of 740 ha of vineyards are planted at 400m - 500m elevation.

In his Forbes article on Italian sparkling wines, Tom Hyland identified the Colonnara Tradition Brut as one of the best examples of Verdicchio sparkling wine that he has tasted. The wine, he says, "... offers subdued herbal notes in the finish, along with bright pear and melon fruit."

In that same article, Hyland spoke favorably of a number of Verdicchio/Chardonnay cuvées:
  • Poderi Mattioli Dosaggio Zero -- vintage-dated blend that is aged 48 months on its lees
  • Umani-Ronchi Extra Brut millesimato -- 65% Verdicchio, 35% Chardonnay
  • Umani-Ronchi La Hoz -- 80% Verdicchio, 20% Chardonnay. The Verdicchio is aged in steel while the Chardonnay is aged in mid-sized oak barrels. The wines are aged on lees for 48 months.
Greco di Tufo DOCG
The sparkling wines in Greco di Tufo DOCG are made in the traditional manner and stay on the lees for at least 3 years. According to tasteatlas.com, "These straw yellow wines are intense, herbaceous, floral, and fruity with typical notes of apples, jasmine, thyme, or sage. They are best paired with rich seafood dishes and could go well with lobster or cod ... they are also an excellent aperitif and would be a great match to various appetizers."

Feudi di San Gregorio, one of the leading independent wine producers in Campania, has established a separate label -- DUBL -- under which to market its Spumante wines. This project began in 2004 and was aimed at bringing the classic sparkling wine method to the grapes of the Campanian tradition: Greco, Aglianico, and Falanghina.

Feudi San Gregorio felt that they had the high-quality fruit for such an initiative. The internal areas of the region are ideal for growth of grapes destined for sparkling wines:
  • Diurnal temperature differences would allow grape ripening with acid-retention
  • The ventilation and exposure of the vineyards are ideal
  • Rugged terroir 
  • Volcanic soils.
They did not, however, have the requisite skill. To fill that gap they sought the advice and assistance of Anselme Selosse -- of Jacques Selosse grower-Champagne fame. The wines that resulted were a 100% Greco sparkling wine, a 100% Aglianico sparkling Rosata, and a 100% Falanghina as a Double Brut.

In April 2016, DUBL extended its product portfolio with DUBL Esse, a Dossagio Zero line, with a white sparkling made from the best grapes from the most exciting vineyards in the Tufo area and a Rosata which comes from grapes from the most exciting vineyards in the Taurasi area.

Etna Spumante DOC
In a May 22, 2019, Forbes article on Italian sparkling wines, Tom Hyland stated thusly:
Given that the climate of Sicily is warm, you wouldn't expect sparkling wine to be produced here, but there are some very fine examples. A few producers in the Etna zone are crafting some beautifully rendered metodo classico cuvées, including Planeta, Terraze dell'Etna and Murgo. The wines vary from Planeta's 100% Carricante version to several offerings each from the latter two producers. Terraze dell'Etna produces two offerings of Brut made entirely from Chardonnay, with one being aged on its lees for 50 months, and they also produce two different Rosé Brut, again with one being aged for 50 months on the lees; the rosés are made from 90% Pinot Nero and 10% Nerello Mascalese. ... The finest sparkling wines from Sicily in my estimation.
