Prepare canning jars and lids by washing and heating them before starting the jelly. Get your canning pot on the stove.
Wash the grapes well (organic grapes can have a whole host of creatures that call the cluster home). Remove each grape from the stem. Squeeze them into a large pot. Crush them with a potato masher or similar tool.
Bring the grapes and a bit of water to boil. Reduce the heat and simmer for ten minutes with the pan covered.
3 cups grape juice, 1 cup water
Strain the pulp, skin, and seeds out using a jelly sock or a cheesecloth-lined strainer. Let it strain for a couple of hours.
Pour the grape juice into a large pot. Add the pectin and stir constantly to incorporate it. Heat up the juice to boiling over high heat. Boil for one minute.
3 tablespoons low sugar pectin
Add the sugar. Bring the mixture back to a full rolling boil. (One that can’t be stirred down.) Boil for another full minute. Skim off foam, if needed.
2 cups Sugar
Ladle the hot jelly into hot jars leaving ¼ inch headspace. Remove bubbles if necessary.
Wipe the rim of the jars clean with a damp paper towel to remove any debris.
Center the lid on the jar. Screw on the bands fingertip tight.
Process jars for 5 minutes, adjusting for altitude. After processing is complete, let jars rest in the hot water for at least 5 minutes so that they cool slowly. This will eliminate siphoning.
Remove jars to the counter and leave undisturbed for 12-24 hours until fully cooled. Check seals.Store jars in a cool, dark place for at least one year.
Notes
Makes six half pints.You can make a full-sugar version by substituting classic pectin and increasing the sugar to 5 cups.Pro Tips
Since the jelly is processed for less than 10 minutes, you should use sterilized jars.
This recipe is fine for a water bath canner.
