Thats one of the problems with red wines, they mostly are either sweet or dry with little in the middle. For a lightly sweet try a white Zin or white Merlot. For something on the sweet side a concord fits the bill. then really sweet go for the fruit wines. BUT that said, thats mostly for commercial wines. When you make your own, you can back sweeten anything to your liking, but some wines just dont taste that good sweet. its a personal prefance.
