Home canned grapes have a delicious, wine-like flavour to them.
They are delicious spooned over a bowl of thick Greek yoghurt, or ice cream.
They are also good mixed with some pieces of fresh fruit (such as orange sections and banana slices) for a mixed fruit cocktail — use the juice off the canned grapes as a syrup.
Or, drain and use in savoury dishes such as “Grape, Celery, and Couscous Salad”, or “Pork Medallions with Roasted Parsnips and Roasted Grapes.”
On this page, we work through the USDA procedure for home canning grapes. You may can these in plain water for maximum flexibility, or in sweetened water (see Sweetening Options below.) If you are using table grapes, you may well find they are sweet enough on their own as is.
To be clear, this is a procedure for canning grapes as fruit in their own right: not made into jam, jelly or juice, etc.
Quantities of grapes needed
Numbers are approximate guidelines.
On average, as a very rough guideline, expect to need about 1 kg (2 lbs) grapes per litre (US quart) jar
- 6 kg (14 lb) of grapes = 7 litres (US quarts) canned grapes
- 4 kg (9 lbs ) of grapes = 9 x 1/2 litres (US pints) canned grapes
- 1 lug grapes = 12 kg (26 lbs) = 12 to 14 litres (US quarts) canned grapes
The recipe
If you are going to can these in a sugar syrup (see Sweetening Options below), prepare that first and set aside.
Jar size choices: Quarter-litre (1/2 US pint) OR half-litre (1 US pint) OR 1 litre (1 US quart)
Processing method: Water bath or steam canning
Yield: varies
Headspace: 2 cm (1/2 inch)
Processing time: 10 minutes, all jar sizes
Canning grapes
How to safely home can grapes, following tested USDA methods
Instructions
-
Stem and wash grapes.
-
Have a pot of water boiling.
-
Add the grapes in small batches at a time so that the water will come back to the boil quickly.
-
Let the grapes boil for 30 seconds, then fish out of pot immediately with slotted spoon or sieve.
-
Repeat until all grapes are blanched.
-
Divvy berries out amongst jars, leaving 3 cm (1 inch) headspace.
-
Divvy blanching juice out amongst jars, leaving 2 cm (1/2 inch) headspace.
-
If short of canning liquid, top jars up with boiling water from a kettle.
-
Debubble, top up with more liquid as required to retain headspace.
-
Wipe jar rims.
-
Put lids on.
-
Process jars regardless of chosen size from above in a water bath or steam canner for 10 minutes; increase time as needed for your altitude.
The USDA also gives raw-pack directions for canning grapes.
If you are canning the grapes in plain water, note that raw packs are not generally advised for sugar-free canning of fruit. Raw packs have a shorter quality shelf life; the sugar acts as a bit of a “fixatif” to help extend that a little.
Sweetening options
[Optional] To can sweetened. You can make a light sugar syrup, following the National Center’s directions for a light or very light syrup.
For sugar-free methods, we’ve had tasty sugar-free results using liquid stevia in the following proportions: Per quarter-litre jar (1/2 US pint), 1/8th teaspoon liquid stevia. Per half-litre jar (US pint), 1/4 teaspoon liquid stevia. Per 1 litre jar (US quart), 1/2 teaspoon liquid stevia.
You may also wish to try Splenda ®.
Both would leave a clear liquid in the jar.
Some may ask about honey; the downside we can see is that honey could make the jar liquid “murky”; generally in home canning murkiness is relied upon as an indicator of something having gone wrong in the stored jars. Honey would also change the flavour.
Recipe notes
The small quarter-litre (1 cup / 1/2 US pint / 8 oz) jars are handy for baking; you may wish to can some of those jars unsweetened for maximum flexibility when you go to use them.
Note that both red and green grapes will lose their pronounced red and green colours respectively and end up very pale.

When water-bath canning or steam canning, you must adjust the processing time for your altitude.
For stevia, Better Stevia liquid stevia was the stevia used.

How Long do Canned Grapes Really Last?
The recommendation is, for best quality, use within one year. That being said, that’s a general recommendation that has to cover a broad range of storage conditions including the worst such as stuff in the light, in a hot place near a stove. If you store in a cool, dark place, your storage life will naturally be extended, and you’ll still have good quality. Note that the recommendation is not to discard after one year: instead, the intention is that those jars should be rotated to the front, so they’ll get used up sooner rather than later.
