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 their winery building and their vineyard date back to the 1800s, when winemaking pioneers first took advantage of a unique position on the valley floor. The east side of their vineyard lies along the foothills of the Vaca mountain range and yields grapes with the kind of bold fruit character that comes from well-drained hillside soils. To the west, their estate lies in the Napa River flood zone. Here, their vines take root in rich, deep clay soild, for grapes with softer, more supple varietal character. From their oldest, rockiest section – the “I” Block, where they source their Cabernet Sauvignon Reserve – to more recent plantings, they strive to maintain balanced vines.
