Since 1992, Don Surh has been making wine with varietals grown in Napa, Sonoma, Monterey and Mendocino counties in California. The 1999 vintage was the first commercial vintage in which 1,100 cases of Napa Valley Cabernet Sauvignon, a Bordeaux blend called Mosaique, and a Napa Valley Zinfandel were produced. Today, product has increased to approximately 3,000 cases annually, across seven varietals.
