Sonoma’s newest tasting room and a fairly young producer, I had a chance-tasting while walking by their tasting room in Vine Alley off the Sonoma Square. I stopped to say hello to Sonoma Mayor Logan Harvey when he told me he was about to do their ribbon cutting for the tasting room. Sosie had been open for tastings for a couple of weeks, but this was their official city opening. I stuck around to taste, buy and watch the ceremony.
