Views of a local who has been in the hospitality side of the wine biz full- or part-time for about three decades. Maybe more importantly, an avid consumer of the local wines for over 40 years. Mostly general comments on the California wine business because that's what I know.
It's not just wine tasting and breweries. Sonoma County has a history of apple production so naturally there are several cideries in the county now with tasting rooms.
