99% of the time all welches juice has persertives (Sorbate) in it so it cant go through fermentation during shelf life. in this case you will end up where you started with plain grape juice. Also it wont taste like a sandwich it will pick up notes of concord grape flavors just like a concord grape. best thing is to use wine grapes or juice they have more fermentable sugars and more of a complex flavor offering.
"Q. Do Welch's juice products contain preservatives?
Welchs ready-to-drink 100% Grape Juice and juice cocktails do not contain any preservatives. However, Welchs ready-to-drink 100% White Grape Juice does contain the preservative potassium metabisulfite, which is added to prevent browning and maintain color. Welchs 100% Sparkling Juices and Sparkling Juice Cocktails also contain potassium metabisulfite, as well as the preservative sodium benzoate. Many of our frozen concentrates and shelf stable concentrates contain sulfites to maintain flavor and color."
