With tasting rooms in both Sonoma and Napa, Twomey Cellars believes a good wine should stay with you long after it's gone. They combine wine-making skill and optimal vineyard techniques to result in consistent, memorable vintages. The Twomey Merlot was named by Wine and Spirits magazine as one of the 10 Most Popular Merlots in 2008. Tours of the winery are available by appointment, and tastings are offered Monday through Saturday at both estates.
