Make sure to use the 100% juice product and not the cocktail. The white grape peach is fantastic. There is a nice thread with a recipe in the wine forum.
Seconding saramc. I have a welches white grape-peach just now bottled and oh my, that's going to be something else for summer consumption. I may make up a gallon and turning into sparkling wine. I certainly will make the wine I just bottled again!!!
