How We Chose These Pressure Cookers Picks
We compared glass quality, seal reliability, size availability, and tested-recipe compatibility across Mason jar brands, then weighed canner-owner feedback on breakage rates and lid seal failures. Only Mason-type jars from established brands that are rated for pressure canning made the list.
Key Takeaway: Buy jars once, buy lids forever. Mason jars and bands last decades of pressure canning, but flat lids are single use, so budget for fresh lids every season.
Best Overall: Ball Wide Mouth Quart Jars
Best for: Pressure canners putting up green beans, potatoes, meats, soups, and stock in family-sized portions who want the easiest packing and cleaning. Why it made the list: Ball has been the reference standard for home canning glass for over a century, and its wide mouth quarts are the pressure canner’s workhorse. The straight, wide opening lets you pack raw green beans upright, slide whole pieces of meat in and out, and get a bottle brush to every corner afterward. The two-piece lid system seals reliably, and quart is the largest size approved for most pressure canning recipes.
- Key specs: 32 ounce Mason-type jar, wide mouth opening, tempered soda-lime glass rated for water bath and pressure canning, uses standard wide mouth lids and bands.
- What we like: Easy packing and emptying, simple to clean thoroughly, reliable seals with fresh lids, reusable for decades if the rim stays perfect.
- What we do not like: Wide mouth lids and bands cost more than regular mouth, and quarts are too large for small households, half-open home-canned food has limited fridge life.
- Who should buy it: Families canning garden vegetables, meats, and stock in volume, and anyone who finds narrow openings frustrating to pack.
- Who should avoid it: Small households canning single-meal portions, pints and half-pints match how they actually eat and process a bit faster.
- Common complaints: Owners report occasional breakage from thermal shock when hot jars meet cold surfaces, and periodic regional shortages of wide mouth lids during peak harvest.
- Size note: Quart is the practical ceiling for pressure canning, most USDA-tested recipes stop at quarts, and half-gallon jars are approved only for certain juices in a water bath.
- Cleaning note: Inspect every rim before each use by running a finger around it, any chip or nick means the jar is demoted to dry storage. Wash in the dishwasher and keep jars hot until filling.
- Alternative: Kerr Wide Mouth Pints for smaller portions at a frequently lower case price.
Pressure Canning Jar Buying Guide
Wide mouth vs regular mouth
Wide mouth jars have straight sides and a big opening, ideal for packing whole pieces, pickle spears, and meats, and far easier to empty and scrub. Regular mouth jars are slightly cheaper, their lids are cheaper too, and the shouldered shape suits pourable foods like beans, chili, and stock. Most serious canners keep both and match the mouth to the food.
Jar sizes and what to can in them
Pints are the most versatile pressure canning size, right for vegetables, beans, and meats for one or two people, with slightly shorter processing times than quarts. Quarts suit family portions and stock. Half-pints shine for concentrated items like canned meats and sauces. Stick to sizes your recipe was tested for, processing times do not scale safely to untested jar sizes.
Lids, bands, and reuse rules
Jars and screw bands are reusable indefinitely while undamaged, but flat lids with sealing compound are strictly single use for canning, a reused lid may seal today and silently fail in the pantry. Buy name-brand lids, tighten bands only fingertip tight before processing, and remove bands for storage so a failed seal is obvious.
Safety Notes
- Use a rack in the canner, jars sitting directly on the bottom metal crack from concentrated heat.
- Never reuse flat lids for canning, and never use lids with dents or dried compound.
- Let the canner depressurize naturally, rapid cooling causes siphoning and seal failures.
- Most electric multicookers are not approved for pressure canning, use a stovetop pressure canner or a digital canner validated for USDA processes.
What to Avoid
- Repurposed commercial jars from pasta sauce or pickles, the glass is thinner and one-time lids do not reseal.
- Vintage bail-wire and zinc-lid jars, they belong on a shelf, not in a canner.
- Any jar with a chipped or nicked rim, it will not seal reliably.
- Off-brand bargain jars with recurring reports of cracking under pressure.
FAQ
Can you reuse canning lids for pressure canning?
No. The sealing compound on a flat lid compresses to fit one jar rim, one time. Reused lids fail at a much higher rate, sometimes weeks after processing when you will not notice. Bands and jars are reusable, lids are consumables.
Why do jars break in a pressure canner?
Almost always thermal shock or contact stress, a cold jar into hot water, a hot jar onto a cold counter, or jars sitting rackless on the canner floor. Keep jars hot before filling, always use the rack, and let processed jars cool on a towel.
Are decades-old Ball jars still safe to use?
If the rim is chip-free and the glass has no cracks or deep scratches, vintage standard Mason jars from Ball or Kerr are generally fine with new lids. Retire any jar with etched, cloudy stress lines, and never pressure can in antique bail-wire styles.
Final Verdict
The Ball Wide Mouth Quart Jars are the best canning jars for pressure canning, with Ball Regular Mouth Pints as the versatile value size and Kerr Wide Mouth Pints as the budget case to stock up on.
