Zinfandel Wine Guide

California's signature grape, producing jammy, fruit-forward wines with spicy character.

What is Zinfandel?

Zinfandel is genetically identical to Italy's Primitivo and Croatia's Crljenak Kaštelanski, but it has become so deeply intertwined with California's winemaking identity that it is often called America's heritage grape. The variety arrived in the United States in the mid-19th century, likely via a Viennese nursery, and quickly spread through California during the Gold Rush era—many of those original plantings survive today as treasured "old vines" that produce wines of extraordinary concentration and complexity from gnarled, low-yielding plants. In regions like Lodi, Paso Robles, and Sonoma County's Dry Creek Valley, Zinfandel produces bold, high-alcohol wines (often 14-16% ABV) with explosive flavors of ripe blackberry, raspberry jam, and warm baking spices that are unlike anything else in the wine world. The grape's uneven ripening—with raisined berries appearing alongside green ones on the same cluster—creates a unique flavor profile that blends fresh fruit with dried fruit intensity, a characteristic that skilled winemakers have learned to harness rather than fight. White Zinfandel, a sweet pink wine created by accident at Sutter Home in the 1970s when a stuck fermentation left residual sugar, became one of America's bestselling wines and introduced millions of consumers to wine drinking. Today, serious Zinfandel from old-vine vineyards ranks among California's most collectible wines, offering a distinctly American expression of terroir that no other grape variety can replicate.
