Producer websiteFounded in 1997 by winemaker Jeff Gaffner, the winery's cornerstone is its 100-year-old Casa Santinamaria Vineyard in Sonoma, a "field blend" vineyard that, at a half ton an acre, defines "low-yielding". Old vine Zinfandel (with its field-mates Petite Sirah, Carignane, Alicante Bouschet and Mataro) and Semillon come from this historic parcel. Pinot Noir and Syrah are sourced from small vineyards throughout Sonoma County. Total production is fewer than 2,000 cases, allowing Jeff to fulfill his mantra: "Winemaking must consume you, or your wines may not be worth consuming."
