It will be frustrating trying to find any of the 25-case production of the 1991 Cabernet Sauvignon Spring Mountain Rattlesnake Hill. This wine is an intensified version of the Spring Mountain cuvee. A profound bottle of Napa Valley Cabernet Sauvignon, it should last for 20-25 years. Readers should make every effort to track down this remarkable wine. This 1991 Cabernet Sauvignon is the first I have tasted from Barnett Vineyards. I was blown away by its excellence. These people understand great winemaking, demonstrating what heights Napa Valley Cabernet Sauvignon can achieve.Assuming distribution for this new producer is limited, readers may need the telephone number for Barnett Vineyards; it is (707) 963-0802.
