The Vision
An Impossible Dream
Dr. Jan Krupp is a physician turned vintner whose determination and vision—shared with his brother Bart—transformed a mountainous stretch of volcanic wilderness spanning Napa Valley’s Atlas Peak and Pritchard Hill into one of California’s most celebrated vineyards.
The Making
Science Meets the Land
A graduate of Yale University and Stanford University School of Medicine, Jan practiced internal medicine for more than two decades before pursuing an audacious dream: to grow world-class Cabernet Sauvignon on land that experts deemed impossible to plant.
Breaking Ground
Blasting Rock, Finding Water
Armed with scientific precision, unyielding perseverance, and a deep belief in the potential of the land, Jan spent years blasting rock, finding water, and nurturing vines in the thin mountain soil. Their creation, Stagecoach Vineyard, would go on to supply fruit to many of Napa’s most esteemed wineries.
The Legacy
Krupp Brothers Winery
Jan later co-founded Krupp Brothers Winery with Bart, crafting wines that reflect the beauty, complexity, and grit of the vineyard they developed. His journey—from healing people to cultivating vines and producing wine—reveals the intersection of science, art and willpower.
