Opus One, Overture, Napa Valley, California, USA (2018 Release)

Opus One is among California’s leading wine estates. It was founded as a joint venture between two leading wine producers: Baron Philippe de Rothschild, the owner of Château Mouton Rothschild in Pauillac, Bordeaux; and Robert Mondavi, one of the most influential figures in Californian wine history. The ambitious pair created Opus One in 1978, the first vintage following in 1979. It is located in the Oakville sub-region of California’s Napa Valley. There are four estate-owned vineyards, including considerable holdings in the prestigious To Kalon vineyard.
