How long to process canned peaches in water bath depends on the jar size you’re using.
For pint jars, you’ll process them for about 20 minutes, while quart jars need around 25 minutes.
These times apply when you’re canning peaches in a boiling water bath canner at sea level.
If you live at a higher altitude, you’ll need to add extra time to ensure safe processing.
Peaches are high-acid fruits, which makes them perfect for water bath canning.
In this post, we’ll walk through exactly how long to process canned peaches in water bath, plus the steps to get them shelf-stable and delicious.
Let’s dive in so you can enjoy your own home-canned peaches all year long.
How Long to Process Canned Peaches in Water Bath
The exact time to process canned peaches in a water bath depends on a couple of factors.
The main ones are jar size and your altitude.
Here’s the breakdown so you get it right every single time.
1. Processing Times for Pint Jars
When you process canned peaches in water bath using pint jars, you’ll need 20 minutes.
This is for raw-packed or hot-packed peaches in a light or medium syrup.
Pints are the most popular size for canning peaches because they’re easier to handle and perfect for small families.
Just make sure your water bath canner is at a full rolling boil before you start counting the time.
2. Processing Times for Quart Jars
If you’re using quart jars, you’ll process canned peaches in water bath for 25 minutes.
Quarts hold more fruit, so they need a little extra time for the heat to penetrate all the way to the center.
Again, this timing is for altitudes of 1,000 feet or below.
Always start your timer only after the water has returned to a full boil once you’ve added the jars.
3. Altitude Adjustments You Can’t Skip
Water boils at a lower temperature as you go up in elevation, so you’ll need to add time when you process canned peaches in water bath.
At 1,001 to 3,000 feet, add 5 minutes.
At 3,001 to 6,000 feet, add 10 minutes.
At 6,001 to 8,000 feet, add 15 minutes.
Above 8,000 feet, add 20 minutes.
This is non-negotiable if you want your canned peaches to be safe to eat.
Steps to Process Canned Peaches in Water Bath
Now that you know how long to process canned peaches in water bath, let’s cover the actual steps.
1. Prep Your Peaches and Jars
Start by washing and sanitizing your jars, lids, and bands.
Then blanch your peaches in boiling water for about 30 to 60 seconds, and transfer them to an ice bath.
This makes the skins slip right off.
Peel, halve, and pit the peaches, then pack them into your clean jars.
2. Add Syrup and Remove Air Bubbles
Pour your preferred syrup over the peaches, leaving about half an inch of headspace.
Use a plastic bubble remover or a thin spatula to slide around the inside of the jar and release trapped air.
Wipe the rims clean, then place your lids and bands on until they’re fingertip-tight.
3. Load the Canner and Start Timing
Place your filled jars on the rack in your water bath canner, making sure they’re covered by at least one to two inches of water.
Bring the water to a rolling boil, then start your timer based on the jar size and altitude adjustments we covered.
Keep the water at a steady boil the entire time you process canned peaches in water bath.
4. Cool, Check Seals, and Store
Once the processing time is up, turn off the heat and let the jars sit in the canner for five minutes.
Then carefully lift them out and set them on a towel to cool undisturbed for 12 to 24 hours.
You’ll hear that satisfying ping as the lids seal.
Check that the lids are concave and don’t flex when pressed, then store your jars in a cool, dark place.
Common Mistakes When You Process Canned Peaches in Water Bath
Even with the right timing, a few slip-ups can ruin your batch.
Don’t start your timer before the water returns to a full boil after adding jars.
Don’t use overripe or bruised peaches, since they turn mushy.
And never skip the altitude adjustment, because that’s a food safety issue.
Also, avoid tightening the bands too much, since air needs to escape during processing.
Follow these tips, and every batch you process canned peaches in water bath will come out perfect.
So, How Long to Process Canned Peaches in Water Bath?
How long to process canned peaches in water bath comes down to 20 minutes for pints and 25 minutes for quarts at sea level.
Add 5 to 20 extra minutes depending on your altitude.
Peaches are high-acid, so a water bath canner is all you need to make them shelf-stable.
With the right timing, proper headspace, and a good seal, you’ll have jars of sweet, home-canned peaches ready whenever a craving hits.
