You can can string beans in a water bath, and it’s one of the easiest ways to preserve your summer harvest.
 
If you’ve been wondering how to can string beans in a water bath, you’re in the right place.
 
While the USDA now recommends pressure canning for green beans because they’re a low-acid food, many home canners still use the water bath method, especially for pickled or acidified string beans.
 
In this post, we’ll walk through how to can string beans in a water bath safely, including the pickled version that works best for this method.
 
Let’s get into it.
 

Why You Might Want to Can String Beans in a Water Bath

Canning string beans in a water bath is a traditional method that many families still use today.
 
The key is understanding that plain string beans are low-acid, which means they need pressure canning to be safe.
 
But when you add acid like vinegar or lemon juice, you can can string beans in a water bath safely.
 
That’s why pickled string beans, also called dilly beans, are the perfect candidate for water bath canning.
 
Here’s why this method works so well for acidified beans:
 

1. Acid Makes Water Bath Canning Safe

The reason you can can string beans in a water bath when they’re pickled is the acid.
 
Vinegar lowers the pH of the beans, creating an environment where botulism bacteria can’t survive.
 
When the pH drops below 4.6, water bath canning becomes a safe option for preserving string beans.
 
So if you’re pickling your beans with a tested recipe, you can can string beans in a water bath without worry.
 

2. Water Bath Canning Is Simpler for Beginners

Many home canners prefer to can string beans in a water bath because the equipment is simpler.
 
You don’t need a pressure canner, which can feel intimidating if you’re new to preserving food.
 
A large pot with a rack is all you need to can string beans in a water bath.
 
This makes it an accessible way to put up your garden harvest without investing in expensive gear.
 

3. Pickled String Beans Taste Amazing

When you can string beans in a water bath with a pickling brine, you get tangy, crunchy beans that are perfect for snacking.
 
They’re great on charcuterie boards, in salads, or straight from the jar.
 
So learning how to can string beans in a water bath opens up a world of flavorful possibilities.
 

How to Can String Beans in a Water Bath Step by Step

Here’s how to can string beans in a water bath using the pickled method, which is the safe way to do it.
 

1. Gather Your Ingredients and Equipment

To can string beans in a water bath, you’ll need fresh string beans, vinegar, water, pickling salt, and spices like dill, garlic, and peppercorns.
 
You’ll also need clean mason jars, lids, bands, and a large stockpot with a rack.
 
Make sure your jars are washed and kept hot before you start filling them.
 

2. Prepare Your String Beans

Wash your string beans and trim the ends.
 
You can leave them whole or cut them into pieces that fit your jars.
 
Packing them upright makes a prettier jar, but any way works when you can string beans in a water bath.
 

3. Make the Pickling Brine

Combine equal parts vinegar and water in a saucepan.
 
For every cup of liquid, add one tablespoon of pickling salt.
 
Bring the brine to a boil, then reduce to a simmer while you fill your jars.
 
This brine is what allows you to can string beans in a water bath safely.
 

4. Fill Your Jars

Pack the string beans tightly into hot jars, leaving half an inch of headspace.
 
Add your spices, then pour the hot brine over the beans, covering them completely.
 
Run a knife around the inside to remove air bubbles, then wipe the rims and seal with lids.
 

5. Process in the Water Bath

Place the jars in your water bath canner, making sure they’re covered by at least an inch of water.
 
Bring the water to a rolling boil and process pint jars for 10 minutes and quart jars for 15 minutes.
 
After processing, turn off the heat and let the jars rest for five minutes before removing them.
 

Tips for Success When You Can String Beans in a Water Bath

Follow these tips to make sure your water bath canning goes smoothly.
 

1. Use a Tested Recipe

Always use a tested recipe when you can string beans in a water bath.
 
The vinegar-to-water ratio matters for safety, so don’t reduce the acid.
 

2. Don’t Skip the Headspace

Leaving the right amount of headspace helps your jars seal properly.
 
Too little headspace can cause brine to leak out during processing.
 

3. Let Jars Cool Undisturbed

After you can string beans in a water bath, let the jars sit for 12 to 24 hours.
 
You’ll hear that satisfying pop as the lids seal.
