From The Russian River Valley Winegrowers website:
The Russian River Valley is located in the heart of Sonoma County, CA. Our growers and winemakers not only produce world-class Pinot Noir and Chardonnay, but also many other cool-climate-loving varietals that express themselves beautifully in our cooler region. We invite you to explore our site and see why we call the Russian River Valley paradise.
The Russian River Valley encompasses more than 15,000 acres of grapevines, 35 varieties of wine and 110 wineries. While this gives us incredible diversity, there is still a common thread among them all: hand-crafted wines of exceptional quality, richness and bright natural acidity and wineries made up of passionate and dedicated people who love the region we call home.
