About Krupp Brothers
Krupp Brothers began as a dream shared by Jan and Bart Krupp—two brothers with a deep love for wine. While running a busy medical practice in the Bay Area, Jan spent years honing his winemaking skills before moving to Napa in 1991. With Bart’s help, he transformed rugged land into what is now the famed Stagecoach Vineyard.
In 1999, the brothers launched Krupp Brothers with their first vintage: a bold, expressive Cabernet Sauvignon. Today, each wine—from our mountain-grown Chardonnay and Cabernets to our Syrah and Tempranillo blend—reflects the care, curiosity, and vision that started it all. We invite you to taste the story in every glass.
Stagecoach Vineyard
With red, rocky volcanic soil, rising 1,900 feet above sea level, Stagecoach produces some of Napa Valley's most remarkable and coveted fruit.
Our Team
