How to Can Blueberries Without Sugar
Learning how to can blueberries without sugar comes down to a few simple steps.
1. Choose Fresh, Ripe Berries
Start by selecting firm, ripe blueberries that are free of bruises or mold.
The better your berries, the better the final product when you can blueberries without sugar.

Sterilize your canning jars and lids before you begin.
Keep your jars hot until you’re ready to fill them.

3. Pack the Blueberries Into Jars
Fill your hot jars with blueberries, leaving about half an inch of headspace.

4. Add Hot Water or Juice
Instead of sugar syrup, pour hot water or unsweetened blueberry juice over the berries.
This is the key trick when you can blueberries without sugar.
The liquid helps fill the gaps and keeps the berries submerged during processing.

Wipe the jar rims, seal the lids, and process in a boiling water bath canner.
Pints typically need about 15 minutes, and quarts need about 20 minutes, depending on your altitude.
Once processed, let the jars cool and check that the lids have sealed properly.

Leaving proper headspace allows the berries to expand during processing.
Overpacking can lead to poor seals when you can blueberries without sugar.
