Zinfandel (genetically identical to Italy's Primitivo and Croatia's ancient Tribidrag) is California's celebrated powerhouse red grape. Boasting bold, hedonistic flavors of blackberry jam, sweet dried raisins, cracked black pepper, and campfire smoke, it delivers immense body and warming alcohol (frequently 15–16% ABV) without harsh tannins.

Frequently Asked Questions
Are Zinfandel and Italian Primitivo the same grape?
Yes. Comprehensive genetic DNA fingerprinting by UC Davis professor Carole Meredith proved that California's Zinfandel, southern Italy's Primitivo (Puglia), and Croatia's ancient Tribidrag are genetically identical. Stylistically, California Old Vine Zinfandels tend to be more opulent, jammy, and barrel-spiced, whereas Italian Primitivos offer slightly rustier, sun-baked Mediterranean earthiness.
What is White Zinfandel?
White Zinfandel is an accidental commercial invention from 1972, created when a stuck fermentation at California's Sutter Home winery left residual sugar in a pale pink saignée run-off. It is a mass-market, sweet, inexpensive pink blush wine. Serious wine enthusiasts distinguish it entirely from bold, dry, complex red Zinfandel.
Why does red Zinfandel often taste distinctly sweet or jammy?
Zinfandel clusters ripen notoriously unevenly: a single bunch can contain green, ripe, and sun-shriveled raisin berries all at once. Because sugar levels are sky-high, yeast often leaves behind 4–8 g/L of natural residual sugar before giving up around 15.5% alcohol. This subtle residual sweetness, combined with luscious blackberry compote fruit, creates a luxurious jammy richness.
