The original recipe I gave you was straight out of the Ball canning book. This recipe make a very dark, very thick juice. Hubs and I prefer it watered down with equal portions of water. Your work goes a lot way.
This version is courtesy of my mother-in-law who's a teacher and is a bit busy during the harvest season. This is a SUPER easy, SUPER fast recipe. If you can get your hands on fresh Concord grapes, there's no reason not to give this a shot.
Yup, that's it.
*Keep in mind, you don't need a "canner" to boil your jars. You just need a deep enough pot to get 1" of water higher than the lid of your jars. In other-words, you can do this without the special, fancy equipment.
