CABERNET PFEFFER: Variety reported developed in California in the late 1800's as a cross between Cabernet Sauvignon and an unknown variety by the gentleman whose name is immortalized. Another report claims that the variety is in fact Trousseau. At last report it is now only found in one very old vineyard, located in San Benito county, California, the fruit from it occasionally made into a spicy, somewhat peppery, curiosity red wine varietal of good quality by whimsical winemakers.
