About Three Wine Company
Three Wine Company built its identity on sustainably produced, traditional California varieties, with a focus that runs through Zinfandel, Carignan and Mataro, heritage grapes with deep state history.
The official site still describes a Clarksburg tasting room, though the current Old Sugar Mill roster does not list the producer, so the present visitor location should be verified directly before a trip.
For drinkers who chase old-California field-blend character, the wines themselves are the draw; confirm where they are currently pouring and the visit follows.
