PlumpJack, in Oakville, was founded by Gordon Getty, a San Francisco composer and philanthropist, and Gavin Newsom, former San Francisco mayor. The entrepreneurs opened a wine shop in San Francisco in 1992 called PlumpJack, a reference to Shakespeare’s character Sir John Falstaff, who enjoyed food and wine. The partners founded the PlumpJack winery in 1997 when they acquired 53 acres of vineyards on Oakville Cross Road. The PlumpJack Group now also includes resorts, hotels, restaurants and spas. The winery specializes in premium Cabernet Sauvignon, though it also makes a Syrah. Robert M. Parker Jr. notes that all the PlumpJack wines “are fabulous, thanks to the brilliant efforts of winemaker Tony Biagi and consultant Nils Venge.” A bit of wine world trivia: PlumpJack was the first Napa Valley producer to use screw caps.
