The Super-Easy Way to Can Grape Juice

Recently, a friend gave me a box of grapes. They weren't the best for eating fresh because they had large seeds. But I knew I could make grape juice with them. And the method - brought to my attention by my mom-in-law - is so, so easy - and not at all messy.

The recipe comes from the 1984 Ball Blue Book. Yes, certain canning guidelines have changed since then. And it's true I could not find this method mentioned by any trusted source (like any of Ball's current publications or over at NCHFP). So, I have to say "can at your own risk," even though my mom-in-law has used this recipe many times.

What You'll Need:

Washed, firm, ripe, de-stemmed grapes, any type (for every quart of juice, you'll need 1 cup)
Granulated sugar (for every quart of juice, you'll need 1/2 cup)
Water

Quart canning jars, lids, and rings
Boiling water bath canner
Ladle
Funnel (optional, but helpful)
Large pot

How to Can Grape Juice the Super-Easy Way:

1. Review the guidelines for water bath canning.

2. Fill the pot with water and bring it to a boil.

3. Work one jar at a time, and make sure each jar is hot: Pour 1 cup of grapes into the jar, followed by 1/2 cup of sugar. (The sugar is not optional.) Fill the jar with boiling water, leaving 1/4 inch headspace. Wipe the rim of the jar, add the lid, and secure the screw band. Place jar in the canner, which must be filled with hot water.

 
Left: Grapes and sugar added. Right: Boiling water added.
4. Repeat until the canner is filled with jars, or until you run out of grapes.

5. Process jars for 10 minutes.*
Wait at least a month before opening a jar. To use, shake the jar, then strain the contents through some cheese cloth (or a sieve lined with coffee filters). It's okay if the sugar settles to the bottom of the jar; just shake before using. It's also okay if the grapes float - or if they do not. (Whether or not the grapes float depends upon the stage of ripeness of the fruit.)

* NOTE: If you live at a high altitude, read this important information about adjusting canning times.
