The wineries at the Old Sugar Mill, in Clarksburg, California, are a bridge to the rich agricultural heritage of the region, whose vineyards are staking their claim alongside the great wine growing regions of the world.

The Old Sugar Mill is home to a unique community of nine California wineries and their signature wines: Todd Taylor Wines, Three Wine Company, Merlo Family Vineyards, Rendez-vous, Heringer Estates, Clarksburg Wine Company, Elevation Ten, Due Vigne di Familiga, and the Carvalho Family Wines. The majority of the vineyards are located in the Clarksburg AVA (American Viticulture Area), where vineyards share the same morning fog and cool breezes from the San Francisco Bay that shape the growing seasons in the vineyards of Napa and Sonoma.
