Constant’s youthful 2004 Cabernet Sauvignon Diamond Mountain Vineyards reveals a deep ruby/purple-tinged color as well as lots of raspberry and blueberry fruit. From a 2,100-foot elevation, this elegant, cool climate Cabernet Sauvignon (which includes small amounts of Cabernet Franc and Merlot) shows no hint of herbaceousness or the earthy underbrush character high elevation vineyards can produce when they do not achieve full ripeness. With medium body as well as outstanding concentration and purity, should continue to evolve and drink well for another 15-20 years, developing even more fragrance as it ages. It is filled with finesse, a characteristic Napa is often accused of not being able to produce. (RP)
