Ravenswood Winery in Sonoma, California. Expressing our commitment to full-flavored varietal wine, notably Zinfandel, sums up our mission to capture everything a vineyard has to offer, and to promote it in a way that won't put people to sleep. Wine is, after all, one of the most fascinating and fun things in life, which is why Ravenswood winemaker Joel Peterson believes that it belongs on the table, not on a pedestal or in an ivory tower.
