Ridge Geyserville, a zinfandel-based blend from Alexander Valley, is a classic among the winery’s stellar lineup of zins and zin blends. The wine has been produced since 1966, making it the Ridge zin with the longest continuous production.

   The blend changes from vintage to vintage, with zinfandel accounting for the lion’s share. (The amount of zin usually falls below the threshold that would allow the wine to be labeled as zinfandel.) The 2024 is 71 percent zinfandel, with a generous amount of carignane and smaller portions of petite sirah and alicante bouschet.

   The 2024 Geyserville, made from three adjoining vineyards, is ripe and plush, yet offers nice freshness and balance. The flavors lean toward blackberry, raspberry, mocha and baking spice, and there’s a persistent finish. At $56, the wine is on the pricier side. A more affordable alternative is the 2024 Three Valleys, another zin-based blend (67 percent zinfandel), which sells for $36 and can sometimes be found for less. It doesn’t have the weight and richness of the Geyserville, but its lively, brambly red berry flavors make it a pleasure to drink.
