Alexander Valley
アレキサンダー・ヴァレー
Sonoma's warmest AVA, home to world-class Cabernet Sauvignon.
Alexander Valley is a prominent American Viticultural Area (AVA) located in northeastern Sonoma County, California, just north of Healdsburg. Established in 1984 as the county's eighth AVA, it spans over 67,000 acres with approximately 14,500 acres planted to vines. The valley is the warmest AVA in Sonoma County during the day, but cools rapidly at night, creating pronounced diurnal temperature swings that preserve acidity and enhance phenolic development. The Russian River moderates inland heat through consistent airflow and morning fog. Alluvial gravel and sandy loam soils, rich in calcium and minerals, lend structure and complexity to the wines. The region is particularly celebrated for its world-class Cabernet Sauvignon, which displays a rich, fleshy mouthfeel and velvety texture. Notable producers include Silver Oak, Jordan Winery, Simi, Francis Ford Coppola Winery, and Ridge Vineyards.
Best for: Lovers of bold, full-bodied Cabernet Sauvignon and Merlot seeking a warm, scenic wine country experience in Sonoma County.
