While driving up to Mendocino, we stopped at Foursight Winery as we'd heard they label their wine as vegan. Indeed they do. We arrived just as they were closing, but the owner graciously stayed open for us to have a wine tasting. We tried 3 whites and 3 reds. We had a lovely time drinking the wine and talking with the owner. We bought the Semillon and the Zero Pinot Noir. The tasting is $5 per person if you don't buy any bottles. Highly recommended if you are in the area.
