If you’re new to home food preservation, you’ve likely heard about water bath canning and pressure canning. While they may sound similar, they serve very different purposes — and using the wrong one can be unsafe.
This guide breaks down the key differences, when to use each method, and what equipment you’ll need, so you can confidently choose the right option for your kitchen.
What Is Water Bath Canning?
Water canning is my preferred method, only because I am not as familiar with pressure canning, and watching that little dial go up and down for an hour gives me butterflies in my stomach.
I hope you fall in love with canning the way I have. The aromas filling the house from canning are simply the best. The feeling of canning food for your family is unlike anything else. I promise you will feel so accomplished when you can look at your bounty.
Water bath canning is a method where jars of food are submerged in boiling water for a specific amount of time. It is imperative that you use safe home canning methods to ensure long-term safety of your food.
There is nothing more disappointing than taking all the time to do canning, only to open a jar and find it spoiled. It’s disappointing, but, it’s nothing you need to fear.
How It Works
- Jars are placed in a large pot of boiling water
- The water must cover the jars by at least 1–2 inches
- Heat kills bacteria and creates a vacuum seal as jars cool
Best Foods for Water Bath Canning
Water bath canning is only safe for high-acid foods, including:
- Fruits (peaches, apples, berries)
- Jams and jellies
- Pickles and relishes
- Tomatoes with added acid (lemon juice or citric acid)
- Fruit juices
High acidity prevents the growth of harmful bacteria like botulism, which is why water bath methods are safe for these foods.
Always follow tested recipes from trusted sources, like the USDA Complete Guide to Home Canning or your local extension office.
Equipment You’ll Need
- Large water bath canner or deep stock pot
- Canning rack
- Glass canning jars with lids and bands
- Jar lifter and basic canning tools

Pros of Water Bath Canning
- Simple and beginner-friendly
- Lower equipment cost
- Ideal for small batches
- Great for seasonal fruit preservation
Cons
- Limited to high-acid foods only
- Not safe for meats, vegetables, or soups
What Is Pressure Canning?
Pressure canning uses steam under pressure to reach temperatures higher than boiling water.
Pressure canning is not my favorite, but I certainly have done it. I do not can meat. Instead, I vacuum seal leftovers or soup starters so I stick with water bath canning. I have certainly done it, but, it made me nervous. My mom taught me water bath canning, so I prefer what I know.
How It Works
- A sealed pressure canner traps steam
- Internal temperatures reach 240°F or higher
- This destroys bacteria that boiling water cannot
This higher temperature is essential for low-acid foods, where botulism spores can survive otherwise.
Best Foods for Pressure Canning
Pressure canning is required for:
- Vegetables (green beans, carrots, corn)
- Meat (beef, chicken, pork)
- Poultry
- Seafood
- Soups, stews, broths
- Beans and legumes
Equipment You’ll Need
- Pressure canner (not just a pressure cooker)
- Canning jars, lids, and rings
- Pressure gauge or weighted regulator

Pros of Pressure Canning
- Safest method for low-acid foods
- Preserves a wider variety of foods
- Long-term shelf stability
- Ideal for homesteading and bulk preservation
Cons
- Higher upfront cost
- Steeper learning curve
- Requires careful timing and pressure monitoring
Water Bath vs. Pressure Canning: Side-by-Side Comparison
| Feature | Water Bath Canning | Pressure Canning |
|---|---|---|
| Temperature | 212°F (boiling) | 240°F+ |
| Food Type | High-acid foods | Low-acid foods |
| Equipment Cost | Lower | Higher |
| Skill Level | Beginner | Intermediate |
| Safety for Meats | ❌ No | ✅ Yes |
| Shelf-Stable Results | ✅ Yes | ✅ Yes |
Which Method Should You Choose?
The right choice depends entirely on what you plan to preserve.
- If you love making jams, fruit butters, pickles, or tomato products, water bath canning may be all you need.
- If you want to preserve vegetables, meats, soups, or full meals, pressure canning is not optional—it’s required for safety.
Many experienced home preservers eventually own both, using each method for what it does best.
Can You Use a Pressure Cooker Instead of a Pressure Canner?
This is a common question—and an important one.
Pressure cookers are NOT the same as pressure canners.
Pressure cookers are designed for quick meals, not safe food preservation.
Check out some of the most common below:
They:
- Do not hold enough jars
- Often don’t maintain consistent pressure
- Are not tested for canning safety
If your goal is shelf-stable food storage, always use a tested pressure canner.
