Chardonnay is the great shapeshifter - from lean, mineral, unoaked bottlings to rich barrel-fermented styles. Tasting it across several producers in one region is the fastest way to learn what the grape actually does versus what the barrel does. Sonoma's Chardonnay heartland runs through the Russian River Valley and Carneros, where fog and cool nights keep the acidity bright. Our enrichment research has tagged at least 227 Sonoma County wineries for Chardonnay - every one profiled below the fold on this site.
