Since its inception in 1992, the Lake County Winegrape Commission has marketed the premium Lake County winegrape growing region to new and existing grape buyers and wineries all over California. The Commission also assists growers in a variety of activities including educational and research programs that benefit growers' vineyard development.

In 1991 when the statewide California Winegrape Commission was voted down, Bob Roumiguiere a local Lake County grower and president of the Grape Growers Association, saw the opportunity for local Lake County Winegrape growers to band together and with the LCGGA, spearheaded the creation of a local commission dedicated to the marketing and research of Lake County's premium North Coast Winegrapes.

Now in its 15th year, the Lake County Winegrape Commission has been instrumental in developing the Lake County winegrape region's unwavering commitment to high quality winegrapes through education, marketing, and research. Lake County winegrape sales have increased to $39 million dollars in sales in 2006 and is one of the many positive forces marketing Lake County agriculture.
