Market Research

Learn about supply and demand trends and forecasts for Lake County wines and winegrapes in “Supply and Demand for Lake County Winegrapes and Wines,” a custom research report prepared by Christian Miller of Full Glass Research. Commissioned by the Lake County Winegrape Commission, the research report provides both quantitative and qualitative data with an emphasis on Lake County’s two main varietals – Cabernet Sauvignon and Sauvignon Blanc – and includes results from a comprehensive 2014 survey of Lake County winegrape buyers.


Lake County Winegrower Vineyard Signage Program

The Lake County Winegrape Commission has established a Vineyard Signage Program designed to support local winegrowers in branding their own vineyards and to convey a professional image of the region as a whole. View more information and download an order form.


Sustainable Winegrowing Information

According to CSWA, sustainable winegrowing is:

  • Good for the environment – Sustainable winegrowing preserves natural resources, improves air and water quality, and protects ecosystems and wildlife habitat.
  • Good for the community – Sustainable winegrowing helps growers and vintners be stewards of both natural and human resources, preserving open space and providing scenic landscapes.
  • Good for grapes and wine – Sustainable practices require in-depth attention to detail and continuous improvement resulting in high quality California winegrapes and wine.

Wildfire Resources

Wildfires have impacted many regions across the state of California over the past several years. Most Lake County vineyards suffered little or no damage in these fires – and in some cases even acted as a firebreak that helped to slow the spread of fires. For growers who were impacted, resources for remediation and rebuilding are available. Information is available on the Wildfire Resources page.


Water/Drought Resources

In response to the statewide drought situation, the Lake County Winegrape Commission has gathered the following resources and information relevant to Lake County winegrowers.
