Sustainable Winegrowing Information
The California Sustainable Winegrowing Alliance (CSWA), Wine Institute, and California Association of Winegrape Growers offer the California Code of Sustainable Winegrowing Workbook online, free of charge, to all California vintners and growers.
In 2015, several wildfires impacted parts of eastern and southern Lake County. While most vineyards suffered little or no damage – and in some cases even acted as a firebreak that helped to slow the spread of the fires – a handful of vineyards in southern Lake County were affected. For those growers, resources for remediation and rebuilding are available. Information is available on the Fire Resources page.
In response to the statewide drought situation, the Lake County Winegrape Commission has gathered the following resources and information relevant to Lake County winegrowers.
