Editorial profile

Krupp Brothers is a Napa Valley winery founded in 1999 by brothers Dr. Jan and Bart Krupp, built around fruit from their Stagecoach Vineyard — red, rocky volcanic soil on the Vaca Mountains above the Silverado Trail — along with the Krupp Brothers estate vineyard, Shake Ridge Vineyard and J-Squared Vineyard.

The portfolio is Cabernet Sauvignon-led (Veraison, Wheelman, M5) but runs unusually wide for a Napa producer of its size, into a Tempranillo-Cabernet blend (The Doctor), a seven-variety red blend (The Water Witch), a Cabernet Franc-Merlot blend (Synchrony), a varietal Viognier (Black Bart's Bride) and Chardonnay and Sauvignon Blanc bottlings. The estate and tasting room sit at the foot of the Vaca Mountains off the Silverado Trail.
