Clos Pegase Winery in Calistoga Showcases $9 Million Architectural Restoration and Cave Art Installations

Wine country architecture enthusiasts and autumn harvest visitors are flocking to Clos Pegase Winery off Dunaweal Lane in Calistoga following an extensive $9 million architectural restoration that returned the Napa Valley landmark to its original design vision. Acquired by Texas winery proprietors Jay and Tammi Adair out of the Vintage Wine Estates bankruptcy proceedings, the estate closed for approximately one year before celebrating its grand reopening in June 2026. Hospitality council leaders and arts patrons from Calistoga, Napa, St. Helena, Walnut Creek, Danville, Alamo, and Lafayette have hailed the project as a triumph of historic preservation.

Originally commissioned in the 1980s by late founders Jan and Mitsuko Shrem through a famous museum design competition organized with the San Francisco Museum of Modern Art, Clos Pegase is renowned for its neo-classical postmodern columns and terracotta colonnades. Tammi Adair explained that her goal was never to reinvent the property, but rather to guide guests on a visual journey that honors the Shrems' original architectural intent. Restoration contractors painstakingly uncovered the original exterior painter's palette while renovating the main tasting room, the Founders Bar, and the central sculpture courtyard.

Honoring the estate's heritage as a temple to wine and fine art, the Adairs commissioned new contemporary installations across the property's indoor galleries and subterranean tunnels. Inside the renovated Founders Room, visitors encounter vibrant mixed-media works by Cuban-American artist Rolando Diaz that echo the estate's mythological Pegasus motif. Beneath the hillside, guests touring the 20,000-square-foot wine cave discover striking figurative sculptures crafted by artist Guy Pederson set against stacked French oak barrels.

Napa County tourism board directors, Calistoga city council planning officials, and agricultural preservation committee members noted that high-investment estate restorations strengthen upper-valley hospitality revenues during the October crush season. Wine industry economists estimate that architectural and culinary tourism generates more than $2.2 billion annually for Napa County districts while supporting local viticulture, hospitality departments, and art galleries. Tasting packages ranging from $45 to $95 per guest now pair single-vineyard estate Cabernet Sauvignon and Chardonnay flights with guided architectural history walks.

Visitors and wine club members can reserve seated courtyard tastings or guided tours of the 20,000-square-foot cave theatre online at clospegase.com.
