Got grape juice? If not, you can make your own from your own grape arbor or even wild grapes. I've done both and prefer wild grapes as they require least maintenance. If the vines are too high in the trees, you might need to cut down the vines and wait a year or two for recovery and grapes at a level you can reach.

The grapes pictured in the walnut tree, both close up and distant shot, are one of many, many wild grape varieties found in Missouri and Arkansas. It is not even certain that all the wild grape varieties have been documented, some of which are sweet, some tart, and some in between, but most are worth the effort to pick this free food.

The pic of the jars of grape juice, JUST CONCORD, and JUST WILD, demonstrate the various methods of grape juice production--in a huge bottling plant, and in your own kitchen, using sterilized former juice jars. I encourage people wanting to eat "naturally" (in the former sense of the word before corporados took over the food system) to experiment with wildcrafting grapes next year, or this year if your climate is still producing grapes.
Enjoy the pics.
