Cabernet Sauvignon, Caldwell Vineyard | Combsville AVA, Napa


The Caldwell family has farmed the southwestern lip of Napa Valley for two generations. The vineyard is farmed with extreme care. Located on a thin soiled, volcanic rim looking north into Napa Valley from their Coombsville porch.  These grapes are usually harvested with high sugar, long hang time (26°-28° brix) and high pH. The grapes and the Caldwell wines have a loyal following. They are ‘out of the ordinary’ and not recommended for beginners, but for those seeking the Best!
