North of San Francisco, the Napa Valley wine country rises 30 miles. This fertile valley is one of the best-known wine regions in the world, especially Cabernet Sauvignon. In the heart of Napa Valley, Baron Philip Rothschild of Mouton Bordeaux and the pioneer of modern viticulture, Robert Mondavi, a representative of Californian wine, joined forces in 1978 to create the exceptional Wine Opus One. Opus One Vineyard consists of 68 acres of vineyards located in the western part of the Oakville wine region in California. The vineyard consists of 4 plots: block Q and block K, River and Ballestra. The 40 hectares of Block Q and Block K are part of the famous terroir of To-Kalon, this deep and gravelly soil, rich in alluvial layers and well drained, makes it an ideal terroir for Cabernet Sauvignon. The vines are carefully pruned into a fence. The 5 traditional grape varieties of Bordeaux-Cabernet Sauvignon, Merlot, Cabernet Sauvignon, Malbec and Petite Verdeaux-have drawn rich and strong flavors from these atypical terroirs, offering excellent craftsmanship and ultimate wine know-how. One of the works is the balance between power and technique, structure and texture. Opus One is a Napa Green certified estate according to the rules put in place by the Napa Valley Vintners organization and we implement more than a hundred favorable and protective procedures for the environment.
