Thomas Coyne Winery in Livermore is Closed
Thomas Coyne Winery
Thomas Coyne Winery was a small-production (under 5,000 cases annually) boutique operation renowned for elegant, hand-crafted Bordeaux and Rhône varietals like Cabernet Sauvignon, Merlot, Syrah, Grenache, Mourvèdre, Petite Sirah, and innovative blends like Petite Verdot. Sourced from diverse California sites, the wines showcased balanced structure, dark fruit, spice, and precise oak aging, earning cult status among enthusiasts for their terroir-driven finesse and food-friendliness. The welcoming tasting room, hosted by Thomas and Emilie Coyne, offered relaxed weekends with personalized flights amid rustic barns and Mt. Diablo views, fostering a mentorship environment in Livermore's collaborative wine community.
Thomas Coyne Winery History
Thomas Stephen Coyne, a chemical engineer from New York, relocated to Livermore in 1977 and ignited his winemaking passion through the Berkeley Ski Club, where he met Kent Rosenblum. He joined Rosenblum Cellars as cellar master in 1988 and launched his label the following year using their Alameda facilities. In 1994 Thomas Coyne purchased the former Chateau Bellevue Winery at 51 Vallecitos Road. He restored winemaking operations, using its massive cellar for barrel aging, and honored its legacy by producing Rhône and Bordeaux varietals—fitting tributes to its French roots. The historic space was ultimately transformed into a production hub for over 20 varietals. The tasting room operated there for 18 years, until a neighborhood dispute over gate access prompted relocation to 2405 Research Drive in 2012. A mentor to many budding Livermore Valley winemakers, Thomas Coyne innovated with tools like ion exchangers for pH adjustment. Following his death in June 2015, the winery closed, with family selling surplus vintages as a tribute. His legacy endures in Livermore's modern era of quality-driven, small-lot winemaking.
Chateau Bellevue Winery was one of California's early stone wineries. It was constructed in 1881 under the direction of French visionary Alexander Duvall, a civil engineer from Bordeaux. He designed the three-building complex—including a massive gravity-flow stone cellar with 18-inch-thick walls—to mimic European châteaux. The site featured underground tunnels and a central courtyard, engineered for natural cooling and efficient wine processing. The Chateau Bellevue buildings are now part of a private estate. Though no longer open to the public, the site remains a quiet landmark along Vallecitos Road.
