The Essential Guide to California Wine Varietals

California's diverse climates and soils allow an extraordinary range of grape varieties to thrive. Here are the state's most important varietals and the regions where they achieve their finest expression.

Cabernet Sauvignon California's most planted red variety, Cabernet Sauvignon reaches its pinnacle in Napa Valley, where the warm days and cool nights of Oakville, Rutherford, and Stags Leap District produce wines of remarkable concentration and structure. Paso Robles and Alexander Valley also produce outstanding Cabernet.

Pinot Noir California's most versatile red variety, Pinot Noir thrives in cool-climate regions where Pacific influence moderates temperatures. Russian River Valley, Sonoma Coast, Santa Rita Hills, and Santa Maria Valley produce benchmark examples with bright acidity, silky texture, and complex red fruit character.

Chardonnay California's most widely planted white variety appears in styles ranging from lean and mineral to rich and buttery. Carneros, Russian River Valley, and Santa Barbara County produce elegant, restrained Chardonnay, while Napa Valley and warmer regions yield fuller-bodied expressions.

Zinfandel Often called California's own grape (though its origins are Croatian), Zinfandel produces some of the state's most characterful wines. Old-vine Zinfandel from the Sierra Foothills, Dry Creek Valley, and Lodi can reach extraordinary complexity and concentration.

Sauvignon Blanc Napa Valley's Sauvignon Blanc — often labeled Fumé Blanc — is among California's finest white wines, with a distinctive combination of tropical fruit, citrus, and herbaceous character.
