A wonderful sweet Concord grape jelly made with fresh Concord grapes. Add the grapes into a very large pot and use a potato masher to crush the grapes as much as possible. Add the water and bring the fruit to a boil over medium-high heat. Cover the pot and simmer for 10 minutes or until the grapes are very soft.
