Canning or Freezing Grape Juice

Wash Jars - 20

The next day we remove the rings and wash the jars in warm soapy water. Failure to remove the rings means you cannot remove any food under the rings. Rings are not needed until the jar is opened. Leaving the rings on invites corrosion under the rings and can lead to much difficulty in removing them at a later date. Any residue of food left on the jar is an open invitation to ants. They will love you for that. When the jars are dry, mark the top with the contents and the year they were canned. A year later it may confuse you which is the grape juice and which is the blackberry jam.
