The most famous of the Beckstoffer vineyards, and one of the most famous vineyards in the new world, Beckstoffer To Kalon was purchased from Beaulieu Vineyard in 1993. Napa pioneer Hamilton Crabb first planted the vineyard in 1868, and it has produced some of the Napa Valley’s best red grapes ever since. Replanted in 1994 to multiple clones of Cabernet Sauvignon and Cabernet Franc with modern trellising and closer vine spacing, the vineyard produces several highly coveted vineyard-designated wines. In 2007 the property was placed under a land conservation easement that forever prohibits non-agricultural development.

Marking the warmest year since 2008, the 2015 growing season set a record for early bloom. Drought conditions persisted, and rainfall was erratic, with most of the much-needed rain falling at the end of the previous year and supplemented by only a single storm in February, which was enough water to sustain the vines. Cooler conditions during flowering ultimately lead to a smaller number of berries on each cluster and lower than average yields. Warm summer months led to advanced veraison, which was followed by perfect ripening conditions. Harvest began in September with short pauses; heat spells and continued warmth allowed for the berries to be steadily picked at their ideal maturity. The harvest was completed in October.
