Louis Foppiano was a Sonoma County vintner and an instrumental figure in shaping the wine industry following Prohibition, serving as one of the early members and later director of the Wine Institute. Born in 1910 in Healdsburg, California, Foppiano grew up on a winery purchased by his grandfather in 1896, attending one year of Santa Rosa Junior College before the onset of the Great Depression. After a brief period traveling with Walter Varney, founder of Continental Airlines, Foppiano took over operations of the family winery and began selling wine in 1932, shortly before the repeal of Prohibition. He went on to expand the Healdsburg winery, acquiring Sotoyome Vineyards and a local cattle ranch, establish the Sonoma County Grape Growers Association, and direct the newly founded Wine Institute. In this interview, Foppiano discusses the early Sonoma County wine scene in the 1930s and 1940s, new bottling and selling processes, Prohibition and Neo-Prohibition, and overall changes to the wine industry over the twentieth century. This interview is part of a group of interviews documenting the California wine industry.
