Trefethen Vineyards

As one of Napa Valley's few remaining family wine estates, Trefethen Vineyards has never purchased a single outside grape. Located in the Oak Knoll District of Napa Valley, our estate vineyard is nestled in a verdant landscape of vines at the cooler, southern end of Napa Valley. During the 1980s, a root louse known as phylloxera, which had devastated Northern California vineyards a century earlier, re-emerged and began a rapid decimation of the world-renowned vineyards of Napa and Sonoma counties. As a result, we planted over 10,000 new vines, utilizing the experience we'd gained over the previous 20 years and implementing many of the successful vineyard experiments we had conducted during that time. In truth, phylloxera provided an opportunity to re-assess what we had originally planted and where. Aided by winemakers David Whitehouse Jr. and Peter Luthi, we carefully researched which varietals, rootstocks and clones to plant in the different sections of our revitalized vineyard, initiating a costly ten-year project that by the first years of the 21st century had both literally and figuratively borne fruit.
