Blend until smooth. Add the syrup, plum wine, and lemon juice and continue processing. Pour the mixture into a 13x9x2-inch nonaluminum or glass baking pan. Freeze for about 1 1/2 hours.

But red wine isn't just for sipping, and next time you have a couple of glasses remaining in that shareable bottle of grape and plum-tinted goodness, don't just mindlessly polish it off.
