The history of the Ridge Three Valleys began with the release of the 2001. The wine contains grapes from a number of Sonoma vineyards—this year, ten. We take great care in selecting the fruit, which is hand-harvested, then crushed and fermented on its native yeast and naturally occurring malolactic bacteria at both Monte Bello and Lytton Springs wineries. Unlike our single-vineyard wines, which reflect the distinctive character of each site, Three Valleys represents the blending of vineyards—winemaking—at its finest. Zinfandel determines the wine’s varietal character; old-vine carignane contributes bright fruit and acidity; petite sirah spice, depth of color, and firm tannins.
