Serres Ranch was established in 1924 in Sonoma, CA. The ranch is nestled in the Valley of the Moon, where surrounding mountains narrow down to the smallest part of the valley, creating its own unique microclimate suitable for growing world class red wines. The nearly 200-acre ranch has raised dairy cattle, beef cattle, row crops and wine grapes. Serres ranch is well known through the valley as producing some of the finest red wines such as Merlot, Cabernet Sauvignon, Cabernet Franc, Petit Verdot, Barbera, Petite Sirah, Aleatico, Zinfandel, Malbec, Syrah and Tannat.
