The Clos Du Val Napa Valley Reserve Cabernet Sauvignon 1978, 13.3% alcohol, was properly stored since release. The fill was high, and the cork was still very good and firm.
This wine likely is at the peak, but it could easily last 10 or more years before drying out too much. The color is still quite deep with only a little age showing around the rim. It is a fairly typical classic Napa in character. It has very intense cassis and other dark fruit, an a touch of the typical Napa herbal character. There is a bit of mixed spice. The extract is high, but not overblown. There is enough acid. The medium tannins are now well resolved. The oak is under control. The aftertaste is very long. It is not hot as so many
70s California wines were, perhaps because of the 13.3% alcohol content rather than 16% or more you sometimes found in the 70s. It is a step up from the 1974 regular, which still is a very good wine. It must be near the top of 1970s California CS at the present time.
