In summer’s past we had a concord grape vine that offered us many gallons of grapes. We had enough for me to make a couple batches of jelly and also to can some quarts of grape juice. We liked the homemade (and organic) grape juice so much that we planted a few more grape vines. They are still babies, and unfortunately our original vine (that we brought with us seven years ago from California) finally died over the winter. This week I gathered together two and a half pounds of concord grapes, but I needed four for jelly, according to the recipe on the liquid pectin box.
Grape juice, sugar and a teaspoon of pectin just before boiling point.
