PlumpJack Winery sits squarely in the heart of Napa Valley’s renowned Oakville region, surrounded by a 42-acre estate vineyard highly regarded for the quality of its Cabernet Sauvignon. Both our winery building and our vineyard date back to the 1800s, when winemaking pioneers first took advantage of a unique position on the valley floor. The east side of our vineyard lies along the foothills of the Vaca mountain range and yields grapes with the kind of bold fruit character that comes from well-draining hillside soils. To the west, our estate lies in the Napa River flood zone. Here our vines take root in rich, deep clay soils, for grapes with softer, more supple varietal character. From our oldest, rockiest section—the “I” Block where we source our Cabernet Sauvignon Reserve—to more recent plantings, we strive to maintain balanced vines. Thanks to the full, expressive range of our estate, PlumpJack wines have become known for their intriguing complexity.
