Opus One was founded as a joint venture between Robert Mondavi and the late Baron Philippe de Rothschild of Mouton-Rothschild. The first vintage was 1979, and along with Dominus this is considered as a Napa Valley "first growth". The fruit comes from the tightlyplanted vineyards that surround the winery, and is a blend of 95% Cabernet Sauvignon and 5% Merlot. The wine has a very Bordelais "elevage" with 18 months in new French oak.Opus One
Mocha, espresso, rosemary, lavender, plums and licorice emerge from the 2008 Opus One. Tasted from magnum, the 2008 is beautifully expressive. The firm tannins need more time to soften, but there is a lot to like in the 2008. Today the 2008 is showing beautifully. In magnum, the 2008 can be enjoyed today or cellared up to another 20 years or so. If opened young, the 2008 needs a few hours of air to soften. The bright, floral, spiced finish suggests a long life ahead. Magnum.

Dark red-ruby. Black raspberry and bitter chocolate on the inviting nose. Quite suave on entry, then wild and a bit gamey in the middle palate, with noteworthy energy to the black raspberry and chocolate flavors. Plenty of acidity here, but it's well buffered by the wine's material. In a rather penetrating style, but broadens out impressively on the back end, finishing with chocolatey tannins and superb subtle persistence.
