PlumpJack Winery
John Conover
General Manager

John Conover’s winery background encompasses sales, marketing and management positions with well-respected, super-and ultra-premium California wine producers, including Grgich Hills Cellar (Rutherford), Monticello Cellars (Napa), Lockwood Vineyard (Monterey County) and currently PlumpJack winery (Oakville).

Conover joined PlumpJack as general manager in January 1999 to oversee the daily operations of the estate winery and vineyard, provide strategic direction for the newly-established property, steadily increase production from 1,000 cases to 10,000 cases annually and create the image, awareness and distribution channels that would ultimately support that level of production.

PlumpJack Winery released its first vintage in 1997. The winery currently produces several varietals under the talented direction of winemaker Anthony Biagi and consulting winemaker Nils Venge. The winery’s focus remains its Oakville Cabernet Sauvignon with two limited offerings: PlumpJack Estate and PlumpJack Reserve.
