Grape juice is my absolute favorite thing to can!
So much better than what you can get in the store.
Bottled Grape Juice
Rinse grapes in sink full of cold water after removing all leaves and the majority of the stems.
Place rinsed grapes in juicer and fill the bottom half with water.
Steam grapes for 1 hour (do not start timer until steam is consistently coming out).
Juice may start to overflow before 1 hour; check after 20 minutes, and fill one or two jars.
Place juice in sterilized bottles and top with sterilized lids. They will seal themselves.
