(Wines&Vines) - Two winegrowing districts are headed toward recognition as American Viticultural Areas in California’s Lake County, where an innovative program for vineyard workers has taken shape. The Alcohol and Tobacco Tax and Trade Bureau (TTB) recently informed the Lake County Winegrape Commission that its initial review is complete for the Kelsey Bench-Lake County and Big Valley District-Lake County AVA petitions. According to Gerald Isenberg, director of the TTB Regulations and Rulings Division, the petitions meet necessary regulatory requirements for “the TTB to proceed with rulemaking for the proposed AVAs.”
