Asked October 17, 2019, 12:49 AM EDT

Is it safe to can grape juice without adding sugar? I would really like to not have to add sugar as it's so good already without sugar.

Yes you can "boiling water bath" can grape juice without sugar!
There are just somethings that you want to be very careful of when cooking down the grapes in order to get "just" the juice and nothing else. If you have a steam juicer unit that is great. If you do not have one then I strongly suggest that you follow the reliable recipe for canning Grape Juice from Ball Blue Book. You need grapes and water, stove, large pot, refrigerator, canning jars, boiling water bath canner. Go to the Ball Webpage and search for Grape Juice. Or go to the National Center of Food Preservation webpage and search for Grape Juice.

Grape Juice

Quantity: An average of 24-1/2 pounds is needed per canner load of 7 quarts; an average of 16 pounds per canner load of 9 pints. A lug weighs 26 pounds and yields 7 to 9 quarts of juice – an average of 3-1/2 pounds per quart.

Please read Using Boiling Water Canners before beginning. If this is your first time canning, it is recommended that you read Principles of Home Canning.

Quality: Select sweet, well-colored, firm, mature fruit of ideal quality for eating fresh or cooking.

Procedure: Wash and stem grapes. Place grapes in a saucepan, crush and add just enough boiling water to cover grapes. Heat to simmering and simmer slowly until skin is soft, about 10 minutes at about 190 degrees. DO NOT BOIL. Strain through a damp jelly bag or double layers of cheesecloth. Refrigerate strained juice for 24 to 48 hours. after refrigeration and without mixing, carefully pour off clear liquid and save; discard sediment. If desired, strain the liquid through a paper coffee filter for a clearer juice. When you ladle juice from pan to the coffee filter, be careful not to disturb the sediment on the bottom of the pan, as this is very bitter and will give you a cloudy product that does not taste good. Heat clear grape juice for 5 minutes to 190 degrees. Then fill hot jars immediately, leaving 1/4-inch headspace. Adjust2 piece lids and process according to the recommendations in Table 1.
