Lewis Cellars in Oakville, Napa Valley, was founded in 1992 by Debbie and Randy Lewis. They own no vineyards but source their grapes from Calistoga, St. Helena, Rutherford, Oak Knoll, Carneros and the Russian River Valley. The estate produces Cabernet Sauvignon, Merlot, Syrah, Chardonnay and Sauvignon Blanc. Total production is 9,000 cases annually. The Lewises originally hired Paul Hobbs as winemaker, but today the winemaker is Brian Mox. California wine writer James Laube has written that all the estate’s wines “are of unusually high quality.”
