Rombauer Vineyards operates in St. Helena, the heart of Napa Valley's most prestigious wine country. The winery's portfolio centers on three flagship Proprietor Selection wines: a Zinfandel from Sierra Foothills, a Cabernet Sauvignon, and a Chardonnay. The Zinfandel and Cabernet Sauvignon have each earned an average prestige rating of 94, while the Chardonnay averages 92.6 across assessments by Wine Enthusiast, Wine Advocate, Wine Spectator, and Decanter. These ratings reflect the technical precision and fruit quality that define the winery's approach. Cabernet Sauvignon thrives in Napa's volcanic soils and warm days, developing the structure and dark fruit character the region is known for. The Sierra Foothills Zinfandel brings the bold, spiced intensity typical of that appellation. The Chardonnay rounds the portfolio with the richness and complexity Napa's cool microclimates can achieve. Each wine demonstrates the standards set by St. Helena's most exacting producers.
