Overview
Silver Oak Cellars is a Napa Valley winery established in 1972 in Oakville, California. It began over a handshake between two friends, Ray Twomey Duncan and Justin Meyer, with a vision to focus on one varietal, Cabernet Sauvignon, aged exclusively in American oak. The winery produces Napa Valley and Alexander Valley Cabernets, farms 19 premier estate vineyards, and owns its cooperage in Missouri. It is family owned and operated by the Duncan family, with David and Tim Duncan overseeing winery operations.
History
Silver Oak began over a handshake between two friends with a bold vision: focus on one varietal, Cabernet Sauvignon, aged exclusively in American oak and worthy of cellaring for decades. Ray Twomey Duncan, a Colorado entrepreneur who began investing in California vineyards in the late 1960s, and Justin Meyer, a Christian Brothers-trained winemaker, co-founded Silver Oak out of a Napa Valley dairy barn in 1972, producing only 1,000 cases of their inaugural vintage. Over the next two decades, Silver Oak grew in popularity, and its Napa Valley and Alexander Valley Cabernets sold quickly upon release and became a highly sought-after staple on restaurant wine lists nationwide. After selecting Daniel Baron to succeed him as winemaker in 1994, Justin retired, selling his share of Silver Oak to the Duncan family in 2001. Ray's sons, David and Tim Duncan, own and operate the winery to this day. In 2006, a fire destroyed the historic Oakville winery; rebuilding resulted in better Napa Valley Cabernets and minimized the eco footprint. Ten years after the fire, Silver Oak Napa Valley was designated the world's first LEED Platinum winery for existing buildings, operations and maintenance (EBOM) by the U.S. Green Building Council (USGBC).
