PlumpJack Winery is located in Oakville, in California's Napa Valley. Like many producers in the region, it is famous for its Cabernet Sauvignon wines made in the foothills of the Vaca Mountains.

The estate covers 42 acres (17 ha), encompassing well-drained hillside sites and rich clays on the valley floor. The diversity of terroir here is reflected in the Cabernet Sauvignon wines that PlumpJack has within its collection.

Fruit is also sourced from grower vineyards in Carneros, Rutherford and Calistoga to make a range of varietal wines from Syrah, Merlot and Chardonnay.
