Russian River Valley AVA
Permitted Varieties
Russian River Valley AVA
Overview
Russian River Valley is one of California’s premier cool-climate appellations and arguably America’s finest Pinot Noir region, producing wines of remarkable complexity, elegance, and depth that rival the best of Burgundy. Established in 1983, this Sonoma County AVA benefits from the Pacific fog that streams through the Petaluma Gap each afternoon, creating ideal conditions for Burgundian varieties. The region has become synonymous with site-specific, terroir-driven winemaking, with its diverse soils and microclimates producing Pinot Noir ranging from silky and ethereal to rich and structured.
