The institution of the Volstead Act in 1919 produced yet another boom in the Calaveras wine industry, as wines for sacramental use and home wine making were the only alcoholic beverages allowed under Prohibition. Almost everyone in Calaveras who had a vineyard became a home winemaker or produced sacramental wine, and numerous vineyards were established or replanted, reaching 445 acres by 1924.
