Sonoma’s warmer Cabernet Sauvignon zone. Includes the historic Geyserville and Pagani Ranch sources for Ridge Vineyards’ Zinfandel field-blend bottlings.
About Alexander
Alexander Valley AVA is one of Sonoma County’s warmer Cabernet Sauvignon zones — a Russian River valley extension northeast of Healdsburg with Mediterranean climate distinctly warmer than Dry Creek Valley or Russian River Valley. The AVA produces serious Cabernet Sauvignon (Silver Oak’s Alexander Valley Cabernet is widely distributed; foundational producers like Robert Young Estate and Stonestreet operate at higher tiers) alongside major Zinfandel production from historic field-blend sites. Ridge Vineyards sources its famous Geyserville bottling from old-vine Zinfandel-Carignane-Petite Sirah plots in Alexander Valley; this and Pagani Ranch are among the most editorially significant California field-blend sources. Other notable producers include Lancaster Estate, Verité, and Jordan Vineyard & Winery.
