About Palmaz Vineyards

Palmaz Vineyards is a dedicated estate winery in world-renowned Napa Valley appellation in Northern California, producing wines that reflect the character of diverse soils and the thermal influence of San Pablo Bay. Dr. Julio Palmaz's Mount George estate — the inventor of the coronary stent applied medical engineering precision to win. The estate's commitment to quality viticulture and site-specific winemaking has earned Palmaz Vineyards a respected place among the region's most consistent and genuinely food-friendly producers.

The Napa Valley growing environment shapes everything Palmaz Vineyards produces. Diverse soils and the thermal influence of san pablo bay define the estate's vineyard character, contributing the structure, natural acidity, and terroir specificity that distinguish the finest wines from this appellation. Cabernet Sauvignon, Chardonnay, and Merlot form the backbone of the portfolio, with each variety expressing a distinct facet of the estate's unique growing conditions. Winemaking at Palmaz Vineyards prioritizes transparency and balance over extraction, allowing the appellation's natural character to lead rather than winemaker intervention.

Visitors to Palmaz Vineyards can expect a genuine and unhurried tasting experience that reflects the estate's commitment to quality and hospitality. The tasting room provides an authentic introduction to the estate wines and the Napa Valley appellation. Whether visiting for a focused flight or a deeper exploration of the estate's vineyard programs, Palmaz Vineyards offers the kind of direct producer experience that wine tourism in California wine country is built on — knowledgeable, welcoming, and genuinely connected to the land and the wines it produces.

Palmaz Vineyards isPalmaz Vineyards is the most technologically extraordinary wine estate in the Napa Valley — a feat of medical engineering precision applied to viticulture that could only have been conceived by someone who invented the coronary stent.
Julio Palmaz, whoseJulio Palmaz, whose 1985 invention of the intravascular stent revolutionized cardiovascular medicine and earned him the National Inventors Hall of Fame, purchased the 1,100-acre Hagen Road estate in 1999 and proceeded to excavate an 18-story underground fermentation facility inside the mountain itself.
The underground facilityThe underground facility — a series of caves and chambers carved deep into the volcanic mountain, including a four-story fermentation dome where temperature is regulated by the mountain's natural thermal mass — represents the most ambitious and scientifically rigorous gravity-flow winery construction in California wine history.
