The more traditional method is to raisin wine grapes either on the vine or store them inside to dry them out. Some call it "Straw Wine" but there are numerous names for this method. Basically the same principle as late harvest wine except even drier grapes. Sometimes added to regular wine sometimes pressed with super high brix levels, almost like syrup.
