Located on the western edge of Sonoma's Alexander Valley, Geyserville was Ridge's first source of red wine grapes, other than Monte Bello Ridge. The first vintage 1966 was an essence. The combination of Geyserville's climate, gravelly soils, and varietal mix (zinfandel, carignane, petite sirah, alicante, mataro, etc.) imparts elegance and definition not usually associated with zinfandel. It's hard to describe a "typical" Geyserville. Each vintage is unique, distinct, extraordinary. Yet they do have elements in common, including the blackest of blackberry fruit, peppery spice, tar, cedar. The term "layered" was invented for Geyserville. And the wines change, re-inventing themselves in bottle, developing more nuance and complexity as years pass. The '73 still shines. Most ageworthy of all Ridge "zinfandels," they can be (witness the '97) magnificent when young. Go taste a Geyserville. Any vintage will do.
