The hunt to find unrivaled vineyard land led Dr. Jan Krupp high into Napa Valley's eastern hills to a harsh mountain site, strewn with rocks and choked with chaparral, straddling Pritchard Hill and the Atlas Peak appellation. A physician with a green thumb and a passion for great wine, Krupp purchased a 41-acre property here in 1991 and began clearing the land for his new vineyard.
Four years later he enlisted the help of his brother Bart Krupp, a sharp businessman with an equal devotion to fine wine, to purchase and clear an additional 750 acres. A half-million tons of rock and debris later, the Krupps had carved three of Napa Valley’s most esteemed vineyards out of what had once been considered virtual wilderness: the original Krupp Vineyard, Krupp Brothers Vineyard, and the renowned Stagecoach Vineyard. Surrounded by established neighbors Bryant Family, Dalla Valle, and Chappellet, the Krupps’ low-yielding vines today produce fruit sought after by some of the valley’s most iconic wineries. Only a small percentage of select fruit from the three vineyards goes into Krupp Brothers handcrafted wines under their Veraison, Black Bart, and Krupp labels.
