My Grandmother used to can this and Tomato Juice in half gallon jars….oh how I miss her….maybe just a small portion of her lives on in me.
I canned mine in half gallons, the biggest challenge was finding a pot deep enough to submerged the jars for water bathing. This recipe is for QUART jars. In each quart jar I put…
One cup of grapes (rinsed well).
One half cup of sugar – if desired. I have canned grapes with water and no sugar so I can add stevia when I open and serve.
I filled each jar to with boiling water leaving 1/2 inch head space.
I tightened my hot lids and rings onto the jars (I gave them a little shake to make sure the sugar dissolved).
Then I processed the jars in a boiling water bath for 20 minutes.
The juice does need to sit for at least two months so the juices and sugar can blend. It starts out a pale barely pink color, but within a few weeks begins to darken to a deep purple.
When it comes time to drink the juice, we strain out the grapes as we pour and enjoy!
We have always made this from our home grown Concord grapes, but the same method can be used with any type of grape… and even cranberries!
