An Enologist's perspective on the Virginia wine industry

Forty bloggers from across the US and Canada descended on Northern Virginia last weekend for Taste Camp, "a gathering of journalists and wine bloggers ... in an emerging wine region for an immersive wine weekend."  This truly was immersive and kudos to the organizers and the Loudon County Tourism organization for arranging the event in the first place and for ensuring that the experiences at every stop along the way was of the highest quality.  I would also like to thank all of the winemakers  for the patience and hospitality that was shown us.  You contributed in a positive manner towards, what was for most of us, a significant learning experience.




In that there were 40 accomplished writers in the group, I was positive that every element of our trip would receive comprehensive scrutiny.  In seeking to develop an overarching context of what we saw over the weekend, I turned to Dr. Bruce Zoecklein, Professor of Enology at Virginia Tech, who has worked with most of these wineries for a number of years and so has a unique inside-outside perspective on the issues that they face, the solutions they have implemented and their overall capabilities. In addition to his work as Professor of Enology, Dr. Zoecklein had previously been the State Enologist as well as the head of the Wine/Enology - Grape Chemistry Group (WEGCG).  A fuller description of the roles and responsibilities of Dr. Zoecklein and his organizations can be found here.

I engaged Dr Zoecklein on three broad themes: (i) the working relationship between the University and the winemakers; (ii) the state of the Virginia wine industry; and (iii) his perspective on Linden Vineyards.  I pursued the latter question because I had been signally impressed by the owner as well as by the wines that we tasted while there.


According to Dr. Zoecklein, his objective is to provide a range of technical services  -- on-demand or as a resource -- to the Virginia wine industry.  Within that context he: (i) brings in technical experts from the west coast and around the world; (ii) ensures that the industry is aware of technological and methodological advances around the world -- and assists wineries in implementing those advances if they so choose; (iii) provides a range of written technical material; and (iv) provides analytical lab services. 

As an example of the types of services that he provides to the wine industry, Dr. Zoecklein points to the mid-1990s when a couple of the red varieties with which they were working produced wines with hard seed tannins; a situation resulting from grape and seed maturity issues as well as processing issues. By applying délestage (a fermentation technique that utilizes oxygenation of the juice to produce a softer, fruitier wine) and micro-oxygenation (application of oxygen doses during maturation to soften tannins in a shorter period than in the case of wood and bottle aging) techniques, the WEGCG was able to resolve the problem.  That is only half the battle, however.  The winemakers have to accept this as a solution that is suitable for them.

Dr. Zoecklein refers to the Virginia wine industry as an "industry of Chiefs and Indians."  The approach in the previous example would have been for the Enology Group to make wines using the two techniques and then to gain the buy-in of the Chiefs (the industry leaders).  Once the rest of the industry sees the practice implemented at the leading wineries, it is likely that they will follow on and implement.

Dr. Zoecklein sees the Virginia wine industry as falling into three separate camps.  In the first camp you find wineries that are making wines that are as well crafted as wines anywhere in the world.  The second camp is comprised of wineries that are making good wine but they lack consistency either across vintages or across labels.  The final camp is comprised of the wineries that are "not nearly as noble as the previous two."  The progressive producers recognize that the market is not static and that they must continue to make progress from one season to the next.  That being said, the industry as a whole is beginning to reap the benefits of technology, estate fruit from older vines, and a better understanding of the impact of seasonal variation on grape and wine quality.  This is still a tourism-based industry but the finer producers understand that they have to get into a position where their wines can compete against the finest wines in the world.  Tourism sales will not provide the economies of scale, or drive the economies of quality, required to compete on the big stage.

The industry does have to confront challenges in the areas of (i) the environment and (ii) attitudes of the buying public.  First, in terms of the environment, winemakers have to deal with late frosts, drought, high humidity, and tropical storms in the fall.  They need to continue working to understand these phenomena and then to incorporate their learnings into their viticultural processes.  In terms of the buying public, Virginia is a new wine region and is being regarded with some skepticism.  The challenge for the VA wine community is to get the potential buyer to "taste the wine and not the label."

Dr. Zoecklein sees the industry moving to a consensus on what varieties will do best in Virginia both in the ground and in the market.  He sees Viognier as gaining a reputation and as a variety that can help to provide regional distinctiveness.  He sees Petit Manseng as being a good second choice because it is soil-suitable, it is not planted extensively in the US, and it can be vinified for both a sweet and a dry wine.  Every winemaker is producing Cabernet Franc and they have learned to tone down the herbaceousness which had plagued their efforts to date.  He thinks Cabernet Franc will do best in Virginia as part of a blend.  Dr. Zoecklein sees both Tannat and Petit Verdot as gaining traction in the marketplace.

As regards my question about Linden Vineyards, Dr. Zoecklein sees Jim Law, the owner, as having a quite unique situation vis a vis the other wineries in Virginia.  Jim has dealt with estate fruit for over 25 years and has gained an empirical understanding of what works and what does not.  Jim, according to Dr. Zoecklein, is great at making observations and banking them.  Finally, wine quality factors are in the vineyard and Jim is a great student of viticulture.

In closing, Dr. Zoecklein expressed a strong sense of optimism in that he sees a number of things lining up to increase the pace of the industry's progress.  First, there is a lot of excitement both within and outside the industry because some wineries are crafting fine wines -- and people are noticing it.   Second, there is strong support of the wine industry by the Governor.  According to USAToday.com (2/26/12), "Promoting the bouquet of Virginia's wine industry has been an important part of (Governor) McDonnell's economic development initiatives ... Virginia wine has been at the center of events at the Virginia Executive Mansion, at business meetings and on international trade and marketing missions to India, Israel, and countries in Europe and Asia."  The Governor, according to Dr. Zoecklein, "... understands the inter-relationships between agriculture, production, marketing, tourism, and tax revenues that the Virginia wine industry brings to the Commonwealth.  It is the understanding of the value-added potential that is the genesis of his support."  Finally, Dr. Zoecklein sees Virginia Tech increasing its already extensive support of the industry.

According to Dr. Zoecklein, "The future is bright as this regional industry grows."  More vines are needed in the ground to help fuel this growth but that will be a challenge given the costs associated with agriculture in the state.

The Virginia Wine Industry and the Upcoming Wine Bloggers Conference

In light of the announcement that the next Wine Bloggers Conference (WBC) will be held in Charlottesville, VA, I sought out an insiders perspective on (i) the Virginia wine industry and (ii) the potential impact of the WBC being held in the state.  The person I turned to for his insights was Dr. Bruce Zoecklein, Professor of Enology at Virginia Tech, State Enologist, and head of the Wine/Enology - Grape Chemistry Group (WEGCG), also at Virginia Tech. Before delving into Dr. Zoecklein's expertise, responsibilities, and perspectives, an overview of the VA wine industry is in order.

According to Virginia Tech the VA wine industry:

  • Utilizes 2500 acres across the state for grape growing
  • Generates $35 million annually in tax revenues
  • Ranks 8th in the country in wine production
  • Supports 165 wineries
  • Hosts over 1 million tourists annually
  • Primarily plants Chardonnay, Cabernet Franc, Merlot, and Cabernet Sauvignon.
The industry has the resources of the University and the state at its disposal for grape quality research and improvement initiatives.

The primary resource available to the industry from the University is the Dr.-Zoecklein-led WEGCG which: (i) conducts/oversees wine-related research and provides lab services; (ii) provides an Extension Service; and (iii) conducts onsite visits to wineries for consultation and data collection.  An example of the research conducted by the group is the development of the electronic nose, a tool that allows the grower to assess grape maturity and select optimal pick-time.  The Extension Service provides workshops, short courses, symposia, and printed/online material, all aimed at increasing the knowledge base of industry participants.

In addition to his teaching responsibilities and leading the WEGCG, Dr. Zoecklein also oversees the Enology Service Lab which provides fee-based analysis of wine or juice for in- and out-of-state customers.  The lab is staffed by two full-time chemists and provides chemical, physical, microbiological and sensory analyses upon request.  The lab was initially established to serve the VA industry but expanded its services to customers beyond state lines in order to have enough samples to run through the system to keep overhead down.  Revenues from the lab activities go back to the lab or into the program.

The WEGCG does not have a charter per se but works actively with VA winemakers to (i) lower their cost of production and (ii) increase the quality of their wine grapes.  One of the primary inputs to WECGC activities is the information gleaned from regular roundtables held with the winemakers.  At these meetings, wines are tasted blind and determinations made as to what the sensory problems are.  The WECGC will then design research programs to address the identified issues. Within the larger group of winemakers there is a smaller group of 15 or so who can, and have, worked on the worldwide stage. Dr. Zoecklein listens carefully to the input from this group.  Organizational success is measured by the number of wineries that adopt his recommendations.  As an example he cited the case of fermentable nitrogen in wine where today, based on his recommendation, the majority of winemakers are sending samples to be tested so that they can make adjustments prior to fermentation.

Dr. Zoecklein sees the VA wine industry as still embryonic, still learning what varietals to plant and where to plant them.  At a broader level, however, the industry operates in a favorable political climate peopled with progressive politicians.  The current governor, for example, is very supportive of the wine industry because he sees its potential impact on tourism, state tax revenues, and agricultural economic development.

When queried about VA terroir, Dr. Zoecklein said that VA was all about soil and climate variation: from the sand of the eastern shore, to the red clay of the Piedmont, and with some limestone thrown in for good measure.  What is more relevant in VA, he says, is hydrology -- soil moisture and soil moisture-holding capacity -- and the industry needs to get to a place where they understand the regional differences and its impact on varietals.

Dr. Zoecklein identified a number of challenges confronting VA winemakers:

  • The need to understand the nuances of climate and how those nuances affect winemaking styles
  • The need to understand what technologies are available and the to adopt the ones that are most germane
  • The need to better understand the marketplace and how best to market their wines.  Tourism is the main sales vehicle today but does not provide the economies of scale needed to get production costs down
  • The need to understand the economics of winemaking.  It is easy to spend a lot of money and not get a return on the investment.
The VA winemaking industry will be positively impacted by the WBC being held there next year, according to Dr. Zoecklein.  In his view it will increase industry visibility.  On a broader level, he sees blogs and bloggers as an increasingly important mechanism for getting the word out.

As regards the future, Dr. Zoecklein sees Virginia as part of a strong regional wine industry with, in its case, demonstrated excellence in Petite Manseng and Sauvignon Blanc.   He expects to have access to grant money to expand winemaker sensory training and to create specialized online programs for people looking to get into winemaking.  He sees the presence of technically trained individuals as key to the growth and development of the industry within the state.
