1979 Opus One Proprietary Red Wine Napa USA Magnum

The first-ever vintage of the joint project between Napa Valley's Robert Mondavi and the Baron Philippe de Rothschild of Chateau Mouton Rothschild in Bordeaux, the wine was produced under the combined direction of Tim Mondavi, and Lucien Sionneau, the winemaker of Mouton, at the Robert Mondavi Winery.

A seemingly perfect growing season from bud break to the beginning of harvest, the 1979 vintage was challenged by rains in September. Early harvesting yielded clean, well-balanced fruit and a wine of resilience and finesse, described as having excellent balance, with a delicate but firm structure.

Blend: 80% Cabernet Sauvignon, 16% Cabernet Franc, 4% Merlot
