I am putting together a 6 gal cranberry recipe from this site, Wade's recipe that I have done before and came out good using the exact stuff, and do not have the red grape concentrate it calls for. Is it ok to use an Old Orchard grape juice in its place? It is 100% juice with no sugars added. I'm trying to get this all done before the Daytona is complete, kind of a race. The berries have been pressed and I'm doing the water/sugar now and chemicals next.
