Sonoma Valley AVA

Sonoma Valley AVA is in southern Sonoma County, flanked by the Sonoma Mountains to the west and the Mayacamas to the east. The climate is moderated by the Pacific Ocean’s cool summer fogs and the influence of San Pablo Bay to the south. St. Francis owns 600 acres of carefully chosen, diverse Sonoma County vineyards. The winery’s estate vineyards give it complete control over growing and production, a cornerstone to St. Francis’ quality philosophy. Each of the four estate-owned vineyards has its own soil profile and unique mesoclimate that forms a “tapestry of terroirs” carefully matched to the grape varieties grown there.
