PlumpJack Winery is a boutique winery in Oakville California specializing in premium Cabernet Sauvignon wines. PlumpJack was the first winery in Napa Valley to use screwcaps as a wine closure on super premium wines. The winery is one of several businesses operated by the PlumpJack Group. The name of the company is inspired by the roguish spirit of Shakespeare’s Sir John Falstaff (Henry IV) dubbed Plump Jack by Queen Elizabeth.
