Leon Adams was the founder of the Wine Advisory Board and the California Grape Growers League, later known as the Wine Institute. Born in Boston in 1905 and raised in California, he attended the University of California, Berkeley, while working the Prohibition beat as a reporter for the San Francisco News and later the McClatchy papers. In anticipation of the repeal of Prohibition, he founded the California Grape Growers League in 1932, renamed the Wine Institute one year after the repeal, to popularize table wine in America. He is also the author of several books, including “The Commonsense Book of Wine” and “The Wines of America.” In this interview, Adams discusses his journalism career, financing the Wine Institute, Roosevelt-era regulations, antitrust threats, and the history of wine in California both before and after Prohibition. This interview is part of a group of interviews documenting the California wine industry.
