Clos Pegase, the landmark Calistoga winery at 1060 Dunaweal Lane, reopened to the public on June 27, 2026, after a yearlong restoration that returned one of Napa Valley's most recognizable architectural set pieces to its original glory. The winery was founded in 1984 by art dealers Jan and Mitsuko Shrem, who selected postmodern architect Michael Graves through a 1984 design competition that drew 96 teams. The New York Times has called the estate, with its 20,000 square feet of barrel caves, dramatic Cave Theater, and Mediterranean-inspired grounds, a place of pilgrimage.
Jay and Tammi Adair's Adair Family Wines acquired Clos Pegase in 2024 out of the Vintage Wine Estates bankruptcy and closed the estate for a full restoration rather than piecemeal repairs, temporarily moving production to the sister property Girard. The restoration recovered the building's original exterior palette and renovated the main tasting room, the Founders bar, and the courtyard. Revived historic fountains anchor the grounds, including a restored 17th-century fountain in a tribute garden dedicated to the late Mitsuko Shrem, planted with cherry trees.
The reopening celebration drew owners, winemakers, artists, town officials, and neighbors, with a ribbon cutting, live jazz, and food from Calistoga's Back Street Bistro. Going forward, the estate is leaning back into its founding identity as a monument to wine, art, and architecture: the art program now showcases emerging local artists, and a 2026 Artist Series wine collection, with original artwork on each label, is set to debut later this year. The winery is open daily from 10 a.m. to 5 p.m. for tastings.
