Sonoma, Calif.—The Stewart family purchased Envolve Winery from the founding team of siblings Mike, Kate and Chris Benziger and partner Ben Flajnik. The Stewarts already own the Lake Sonoma Winery and Valley of the Moon wine brands, Madrone Estate Winery in Glen Ellen, Calif. and Quail’s Gate winery in British Columbia’s Okanagan Valley. According to the statement announcing the acquisition, Envolve wines will be poured at the new Lake Sonoma Winery tasting room at 134 Church St. on the historic Sonoma Square. Mike Benziger and Flajnik established Envolve in 2008 and had operated a tasting room off of the Sonoma Square since 2012. The former Envolve tasting room closed at the end of the year. Lake Sonoma Winery winemaker, Kat Adams, will assume all future wine making responsibilities for Envolve.
