2015 · Opus One

Opus One is an Oakville, California estate founded in 1978–79 as a partnership between Robert Mondavi and Baron Philippe de Rothschild, today a 50/50 joint venture between Constellation Brands and Baron Philippe de Rothschild SA. Built around classic Bordeaux varieties, it was created with the aim of making a singular Napa Valley wine that unites the traditions and innovations of both families. The style is presented as an expression of time and place, balancing power and finesse. Notes also highlight a strong sustainability focus, including IWCA Gold Membership, renewable energy use, regenerative farming, precision irrigation, riparian restoration, and a net-zero emissions target for 2050.
