Grape juice made from fresh grapes can be stored in a variety of ways. You can freeze the juice or you can "can" it for later use. Either way, saving the juice for the future is an easy way to preserve the harvest of fresh grapes. Once stored, you can have grape juice ready to drink anytime and not have to run to the store to purchase bottled or concentrate.
Refrigerate fresh grape juice in jars with tight fitting lids in the refrigerator for 5 to 7 days. The juice will begin to ferment if left longer.
Freeze fresh grape juice by pouring the juice into zipper type freezer bags and sealing. Label the bags with contents and the date. Place the bags into the freezer with the zipper top upright. This will prevent spilling if the seal is not complete. The juice will keep up to one year in the freezer. If desired, to protect from freezer burn, double bag the juice.
Can fresh grape juice by filling canning jars to 1/4 inch from the top with juice. Place the canning lids on the top of the jars and secure with the canning rings. Process the jars in a boiling water bath for 10 minutes. Remove the jars from the water bath and allow to cool. Check the tops for proper sealing. This can be determined by pressing the center of the lid. If the lid does not move, the jar is sealed properly.
Place fresh grape juice into ice cube trays and freeze. Check the trays after 30 minutes and insert a toothpick into the center of each section of the tray. This will make a quick grape juice pop snack.
You can also turn grape juice into wine by adding sugar and yeast and allowing the juice to ferment for 45 to 60 days. Figure on two pounds of sugar for every gallon of grape juice use. One package of wine yeast will make up to 5 gallons of wine.
