How to Can Blackberries in a Jar Step by Step

Knowing how to can blackberries in a jar comes down to a few key steps.
 
Follow these and you’ll have beautiful jars of berries ready for winter.
 

1. Gather Your Supplies

Before you can blackberries in a jar, round up clean pint or quart jars, new lids, bands, a water bath canner, and a jar lifter.
 
You’ll also want a funnel and a bubble remover to make the process smoother.
 

2. Prep the Blackberries

Rinse your berries gently under cool water and remove any stems or leaves.
 
Don’t soak them, since that can waterlog the fruit before you can blackberries in a jar.
 

3. Make a Light Syrup

While learning how to can blackberries in a jar, the syrup is what keeps them plump and sweet.
 
Combine about 2 cups of sugar with 4 cups of water and bring it to a simmer.
 

4. Pack the Jars

Fill your jars with berries, leaving about half an inch of headspace.
 
Pour the hot syrup over them, making sure the berries are fully covered.
 
When you can blackberries in a jar, this syrup step is what makes the final product taste so good.
 

5. Remove Air Bubbles

Run a bubble remover or plastic spatula around the inside of each jar to release trapped air.
 
If you can blackberries in a jar without doing this, you risk uneven sealing and floating fruit.
 

6. Wipe Rims and Add Lids

Wipe the jar rims with a clean cloth, then place your lids on and screw the bands on until fingertip-tight.
 

7. Process in a Water Bath Canner

Lower the jars into boiling water, making sure they’re covered by at least an inch.
 
Process pints for 15 minutes and quarts for 20 minutes, adjusting for altitude if needed.
 

8. Cool and Check Seals

Let the jars cool for 12 to 24 hours, then press the center of each lid.
 
If it doesn’t pop back, you’ve successfully learned how to can blackberries in a jar.
