I got the call from great Grandma today that the concord grapes were ready to pick. I got almost ten gallons of grapes picked and am in the process of making them into juice to put in the freezer. Some juice will be made into jelly later this fall when I have time, but the rest will be thawed for us to drink. The juice straight up is too potent to drink alone, it needs water added and a bit of sugar for our taste. Does anyone have a "recipe" that says how many cups of homemade grape juice + how much water to make a how many ounces of drinkable juice? I want to freeze the rest of the juice in amounts so I can just thaw, pour and mix without have extra juice left over. Thanks.
