PlumpJack Winery in the Oakville district of Napa Valley specializes in estate grown Cabernet, Chardonnay, and Merlot. San Francisco politician Gavin Newsom, the principal behind the PlumpJack Group, established the winery in 1997. Grapes are primarily sourced from the winery's estate vineyard, originally founded in 1881, nestled in the nape of the Vaca Mountain range on the eastern side of the Napa Valley.

A panoramic view of the Mayacamas and Vaca Mountains enhances the mischief and wit of the Leavitt-Weaver-designed PlumpJack Winery tasting room and its surrounding 50 acres of Cabernet Sauvignon. Brightly colored walls and spacious patios greet visitors to the very stylish tasting room.

The inaugural release of their 1995 Reserve Cabernet Sauvignon created quite a stir among the wine community, and prompted Robert Parker, Jr. to assign a rating of 95+ points. The 1997 Reserve bottling came with a screw cap closure-the first luxury producer to do so- and turned the wine industry upside down. The winery currently produces Estate Cabernet Sauvignon, Reserve Cabernet Sauvignon, Reserve Chardonnay, Merlot and Syrah.

The PlumpJack Group has over a dozen business ventures in the Bay area including trendy restaurants, nightclubs, wine shops, inns and other businesses. The management is deeply committed to social and global responsibility, delights in challenging traditional business methods, passionately believes that business can be fun, and demands an exceptional experience for each customer.
