About Sonoma

Sonoma Coast AVA is the broadest of the cool-climate Northern California Pinot Noir AVAs — extending from the Marin County line north along the Pacific coast to the Mendocino County line. The AVA as currently defined is editorially problematic because it includes both true coastal sites (which experience persistent ocean fog and chill) and inland sites that are more Russian River-like. The serious work happens in the true coastal portion — the so-called “Extreme Coastal” zone or “West Sonoma Coast” — where producers like Hirsch Vineyards, Flowers, Peay, Marcassin, and Failla make Pinot Noir and Chardonnay of dramatic intensity and high acid balance. The fog-bound coastal sites produce wines that are stylistically more similar to cool Burgundy than to warmer California Pinot zones. A West Sonoma Coast sub-AVA was approved in 2022 (the formal designation “West Sonoma Coast”) to recognize the genuine coastal sites distinct from the broader AVA.

Editorial notes

Practical guidance

True coastal Sonoma Coast Pinot ages 8-15 years from strong vintages. The 2022 West Sonoma Coast sub-AVA approval is editorially important — it formalizes the distinction between true coastal and inland sites. Older wines labeled simply “Sonoma Coast” should be evaluated for source.
