B Cellars was established in 2003 when Jim Borsack and Duffy Keys decided to step back from previous careers and produce wine. Winemaker Kirk Venge soon joined the team. The label and logo stand for the BRIX scale, which is a system used to measure the sugar content of grapes and wine. B Cellars sources grapes from many of Napa’s premier vineyards, producing a large portfolio of blends and single vineyards wines. Included are Cabernet Sauvignon, Pinot Noir, Chardonnay, Sauvignon Blanc and proprietary blends.
