Ridge Vineyards is a legendary California winery, famous for its single-vineyard Zinfandels and Cabernet Sauvignons. The 'Geyserville' vineyard in Sonoma County's Alexander Valley is one of their most historic sites, with vines dating back to the 1880s. The Geyserville wine is a traditional field blend, predominantly Zinfandel, mixed with Carignane, Petite Sirah, and Mataro. It is celebrated for its consistent quality, offering rich dark berry fruit, complex spice, and a structure that allows it to age gracefully for decades.
