Overview

B. R. Cohn Winery is a winery in Glen Ellen in California's Sonoma Valley. Its identity is closely associated with Olive Hill Estate Vineyards, a property acquired by music-industry manager Bruce Cohn in 1974. Cohn was known for managing the California rock band the Doobie Brothers, and he developed the site around a grove of historic Picholine olive trees reported to be approximately 145 years old at the time of the winery's early development. Before establishing a winery under his own name, Cohn sold grapes from the property to other producers for several years. The B. R. Cohn winery was founded in 1984, with Helen Turley serving as its first winemaker. The estate's vineyards are planted primarily to Cabernet Sauvignon, supported by varieties including Pinot Noir, Zinfandel, Petite Sirah, Cabernet Franc, Petit Verdot, and Malbec. Syrah has been offered through the tasting room, while Chardonnay is sourced from the Carneros region. The winery's portfolio has included Cabernet Sauvignon, Merlot, rosé, port, Petit Syrah, and other wines associated with Sonoma and the North Coast. Its early Olive Hill Cabernet Sauvignons received substantial critical recognition: the 1985 and 1986 vintages were reported as having been ranked by Wine Spectator among the top ten wines in the United States and the top fifty worldwide, each receiving a score of 94 points. The 2003 vintage was reported to have received 93 points. B. R. Cohn's North Coast Petit Syrah was also named one of two red sweepstakes winners at the 2007 San Francisco Chronicle Wine Competition. The business expanded beyond wine during the 1990s into artisan olive-oil production. Its specialty-food range has included both flavored and unflavored olive oils, including an organic variety, as well as balsamic vinegars and related gourmet products. The winery has produced vinegar on site from Cabernet, Chardonnay, and sparkling wines. Its stated production method uses the French Orleans process, in which a portion of mature vinegar, sometimes called the mother, is introduced into fresh wine before extended aging in oak barrels. The reported aging period is approximately 18 to 22 months. The portfolio has also included flavored products such as pear Chardonnay vinegar and raspberry champagne vinegar, together with imported balsamic vinegars from Modena, Italy aged for 12, 15, and 25 years. Like many Sonoma wineries, B. R. Cohn has operated a public tasting room and wine club and has hosted weddings and other private or public events. Ownership changed in 2015, when Vintage Wine Estates acquired the winery. Vintage Wine Estates later sought Chapter 11 bankruptcy protection in July 2024 and announced plans involving the sale of its assets, including B. R. Cohn Winery. In late 2024, Adair Family Wines took over B. R. Cohn and four other sister wineries. The available reference material does not establish the winery's current production scale, distribution footprint, leadership team, or detailed post-acquisition strategy.

History

B. R. Cohn Winery developed from a vineyard property in Glen Ellen, Sonoma Valley, acquired by Bruce Cohn in 1974. Cohn had a career managing the California rock band the Doobie Brothers, but his winery venture centered on agricultural land known as Olive Hill Estate Vineyards. The property included a grove of old Picholine olive trees, described in the reference material as approximately 145 years old. During the first phase of ownership, Cohn sold grapes to other wineries rather than producing wine under his own label. Cohn established B. R. Cohn Winery in 1984. Helen Turley was the winery's first winemaker, a role that connected the young label with a winemaking figure who later became well known in California wine. The estate's planting program emphasized Cabernet Sauvignon, while also including Pinot Noir, Zinfandel, Petite Sirah, Cabernet Franc, Petit Verdot, and Malbec. Syrah was associated with tasting-room sales, and Chardonnay was grown in the Carneros region. The resulting portfolio included Cabernet Sauvignon, Merlot, rosé, port, and other varietal wines. The winery's early Olive Hill Cabernet wines became important markers of its reputation. The 1985 and 1986 vintages were reported as being ranked by Wine Spectator among the top ten wines in the United States and the top fifty in the world, with each receiving 94 points. The 2003 vintage was reported at 93 points. In 2007, the North Coast Petit Syrah received further attention when it was named one of two red sweepstakes winners at the San Francisco Chronicle Wine Competition. During the 1990s, B. R. Cohn broadened its business into olive oil and specialty foods. It produced flavored and unflavored olive oils, including an organic offering, and added balsamic vinegars and other gourmet products. Vinegar was made at the property from Cabernet, Chardonnay, and sparkling wines. The winery described its process as the French Orleans method: a starter quantity of mature vinegar is added to fresh wine, after which the liquid is aged in oak barrels for roughly 18 to 22 months. Products included pear Chardonnay and raspberry champagne vinegar, as well as imported Modena balsamic vinegars carrying 12-, 15-, and 25-year age designations. The consumer-facing business has included a tasting room, wine club, weddings, and other events. In 2015, Vintage Wine Estates acquired B. R. Cohn Winery. That ownership period ended amid Vintage Wine Estates' financial difficulties. In July 2024, Vintage Wine Estates filed for Chapter 11 bankruptcy protection and identified asset sales, including the B. R. Cohn property and brand, as part of the restructuring process. In late 2024, Adair Family Wines took over B. R. Cohn and four sister wineries. The available sources do not provide enough information to describe subsequent management appointments, production volumes, distribution arrangements, or whether every historical product remains in the current range.
