This low-lying valley Sonoma County in and its 10,000 acres of vineyards was virtually unknown before 1983, when it was granted official appellation status (Russian River Valley AVA).
It has since established a formidable reputation as a prime spot for challenging varieties like Pinot Noir (29% of the acreage in 2007), which thrives in this cool-climate region. Chardonnay (42% of the acreage in 2007) has also blossomed here, showing a signature lean and restrained profile.
The Russian River Valley climate is influenced by cooling fogs, drawn inland from the Pacific. This natural air-conditioning allows the grapes to develop full flavor maturity over an extended growing season, while retaining their life-giving natural acidity.
