1. Rinse the leaves and pat them dry. Put them in a large jar that has a lid. 2. Pour in the red wine and vodka. Add the sugar and peppercorns, cover, and shake well to dissolve the sugar. Let stand one week, shaking the jar a few times once per day. The leaves will wilt into the wine after a day or so, so not to worry if they aren’t all marinating in the wine at first. 3. When ready, strain the liquid into a bottle using a funnel and a mesh strainer . Discard the leaves. Chill the cherry leaf wine until ready to drink.
