Harley, many people will tell you that the sour cherries make the best wine. Yes, you can use them for wine. We have made cherry wine for years from sour cherries. When we make the wine, we pick, de-stem, and crush the cherries into our fermenter (be careful not to crack the stone) and add simple syrup to an SG of 1.085. I use EC 1118 yeast and I am sure that those on the forum who try different yeast will have other recommendations. We ferment to dry, clear and stabilize with potassium sorbate and then back sweeten to taste. We like a little tartness so our final SG is about 1.005.
