Trentadue Winery is located in the heart of the Alexander Valley AVA. The property was first developed by Andrew Bouton in 1868. For many years, he ran a brisk business propagating and selling fruit trees. Mr. Bouton counted the venerable Luther Burbank as a friend.
In the late 1950s, the Trentadue Family bought the property and began planting new vines during the following decade. In 1962, they established Carignane vines which is now among the oldest examples of this varietal in the United States.
In addition to Carignane, the Trentadues also began planting Sangiovese during the 1970s. This is a notoriously tricky varietal in the New World, but the family grew it quite successfully. In 1984, Trentadue Winery was noted for being the first American producer to make a 100% Sangiovese wine. Additionally, Paul Draper of Ridge Vineyards has purchased fruit from the Geyserville property for many years.
Trentadue Winery currently produces Carignane, Merlot, Petite Sirah, Cabernet Sauvignon, Sangiovese, Sauvignon Blanc, sparkling wine, and several different blends as well as Port-style wines.
