In this post, we’ll walk through how to can whole blueberries step by step, plus a few tips to keep them tasting fresh.
 
Let’s dive in.
 

Why You Should Can Whole Blueberries

Canning whole blueberries is one of the easiest ways to preserve this superfood.
 
Here’s why it’s worth the effort:
 

1. You Preserve Them at Peak Freshness

When you can whole blueberries during peak season, you lock in their flavor and nutrients.
 
Unlike store-bought canned berries that may sit on shelves for months, your homemade jars capture that just-picked taste.
 
Canning whole blueberries means you’re essentially saving summer in a jar.
 

2. It Saves Money

Fresh blueberries can be pricey off-season.
 
But when you can whole blueberries in bulk during summer sales, you stretch every dollar.
 
A flat of berries in July can turn into a dozen jars that last well into winter.
 
That’s a smart way to can whole blueberries without breaking the bank.
 

3. You Control the Sugar and Ingredients

Store-bought canned blueberries often come loaded with corn syrup or artificial additives.
 
When you can whole blueberries at home, you decide exactly what goes in.
 
Want a light syrup?
 
A heavy one?
 
Or maybe you prefer canning whole blueberries in juice or water?
 
The choice is yours.
 

How to Can Whole Blueberries Step by Step

Learning how to can whole blueberries isn’t complicated, but you do need to follow a few key steps for safety and quality.
 
Here’s the process:
 

1. Gather Your Supplies

Before you start canning whole blueberries, make sure you have everything ready.
 
You’ll need:
 
Fresh blueberries (about 12 cups per 6 pints)
 
Mason jars with lids and bands
 
A large water bath canner or stockpot
 
Sugar, honey, or juice for the syrup
 
A jar lifter and funnel
 
Clean towels
 
Having everything within reach makes canning whole blueberries much smoother.
 

2. Prep Your Blueberries

Start by rinsing your berries under cold water.
 
Pick out any stems, leaves, or mushy ones.
 
You want firm, ripe berries for canning whole blueberries.
 
Don’t soak them, just a quick rinse is plenty.
 

3. Make Your Syrup

While the berries drain, prepare your syrup.
 
For a light syrup, combine 2 cups sugar with 4 cups water and heat until dissolved.
 
For a heavier syrup, use 3 cups sugar to 4 cups water.
 
You can also use apple juice or white grape juice if you prefer canning whole blueberries without added sugar.
 
Keep the syrup warm while you pack your jars.
 

4. Pack the Jars

Fill your clean jars with blueberries, leaving about 1 inch of headspace.
 
Gently shake the jars to settle the berries, then add more until they’re tightly packed.
 
This step is key when you can whole blueberries because you want as many berries in each jar as possible.
 
Ladle the hot syrup over the berries, still leaving that 1-inch headspace.
 
Run a plastic knife around the inside to remove air bubbles, then wipe the rims clean.
 

5. Process in a Water Bath

Place the lids on and screw on the bands until fingertip-tight.
 
Lower the jars into your boiling water bath canner, making sure they’re covered by at least 1 inch of water.
 
Process pints for 15 minutes and quarts for 20 minutes.
 
When canning whole blueberries, don’t start the timer until the water returns to a full boil.
 

6. Cool and Check the Seals

After processing, turn off the heat and let the jars sit for 5 minutes.
 
Then remove them with a jar lifter and place them on a towel to cool undisturbed for 12 to 24 hours.
 
You’ll hear that satisfying ping as the lids seal.
 
Once cool, press the center of each lid.
 
If it doesn’t pop back, you’ve successfully canned whole blueberries.
 

Tips for Canning Whole Blueberries Perfectly

Here are a few extra pointers to keep in mind:
 

1. Use Firm, Ripe Berries

Overripe berries turn to mush when you can whole blueberries.
 
Pick berries that are ripe but still hold their shape.
 

2. Don’t Skip the Headspace

Leaving the right amount of headspace is crucial for a proper seal.
 
Too little and syrup may leak out during processing.
 
Too much and the berries may float or discolor.
 

3. Store Jars in a Cool, Dark Place

Once you’ve canned whole blueberries, keep them in a pantry away from heat and light.
 
They’ll stay good for up to a year.
