My mother-in-law Sandra is an expert at canning and over the years has canned quite a bit. This year she let me join her in her harvest of grapes to make some canned grape juice. Now, I don't know why we call it canning when we put it in jars but oh well, we do. Now, obviously this post isn't designed to be detailed how to instructions, but more to demystify the process and show you how simple it can be.
Sandra harvested her grapes before I got there and had three or four tubs full of grapes ready to go. The first step was to wash the grapes. You don't need to stem the grapes - it won't affect the flavor of the juice. But you do need to wash them unless you want the flavor of little spiders and dirt in your juice. We also took out the few dried leaves that had ended up in the batch.
Then pile them into your steamer juicer - all the way to the top. Put the lid on and start steaming them according to your steamer's directions - somewhere around 60 minutes.
During that time the juice will slowly flow out into your waiting container. In our case a pitcher for ease of pouring into our jars.
After your done you'll end up with some pulp that looks like this. You can reserve this pulp to get some diluted juice from it later on if you'd like. It must be good for something!
Once you've got the juice pour it into jars ready for canning. Make sure the top of the bottle is clean and free from juice so the seal can be nice and tight. We then went on with the canning process - boiling the jars for 15 or so minutes and then letting them cool and seal.
And voila! You've got homemade healthy juice to enjoy for a long time. Wasn't that simple? I thought it was and already my boys are begging me to open up yet another jar! By the way, we do dilute our juice a little bit - you might like it 100% or not - just play around a bit to see.
