Best Large-Capacity Pressure Canner: All American 921 vs 930 vs 941

The four sizes in plain numbers

All of the figures below come from All American's own product pages, current as of this writing. They are worth reading as a set, because the pattern is not what the model numbers suggest.

• The 921: 21.5 quarts liquid capacity. Jar load: 7 quart jars (regular or wide mouth), or 18 regular-mouth pints (16 wide mouth). 15.375 inches tall, 12.25 inch diameter, 22 pounds empty. $499.95 direct.
• The 925: 25 quarts liquid capacity. Jar load: still 7 quart jars, with 19 regular-mouth pints (16 wide mouth). 16.75 inches tall, same 12.25 inch diameter, 23 pounds empty. $499.95 direct.
• The 930: 30 quarts liquid capacity. Jar load: 14 quart jars (regular or wide mouth), or 19 regular-mouth pints (16 wide mouth). 19 inches tall, same 12.25 inch diameter, 25 pounds empty. $549.95 direct.
• The 941: 41.5 quarts liquid capacity. Jar load: 22 quart jars or 30 pints. 19 inches tall, 15.25 inch diameter, 36 pounds empty. $649.95 direct.

Read the quart-jar column again, because it is the one that matters and it is not linear. The 921 and 925 both hold seven quart jars; the extra 3.5 quarts of liquid capacity in the 925 buys headroom, not more jars per load. The jump that changes your output is the 930, which holds 14 quart jars, double the 921, in the same 12.25 inch diameter; the extra jars come from the added height, not a wider base. The 941 gets to 22 quarts by finally going wider as well as tall.

What one load actually holds

For pint canners the table gets stranger. The 921 lists 18 regular-mouth pints, the 925 and the 930 both list 19, and only the 941 breaks away at 30. If you mostly can pints of meat, broth, or beans, the 930 barely out-loads the canner two sizes below it, which makes the 930 specifically a quart-jar machine. Know which jar you actually run before you pay for height you cannot use.

Wide-mouth jars also cost you capacity on every model: 16 wide-mouth pints fit where 18 or 19 regular-mouth pints would. It is a small tax, but across a season of double loads it adds up to real jars.

There is also a floor, not just a ceiling, on load size. An oversized canner run nearly empty is not a convenience, it is a malfunction waiting to happen, as one r/Canning regular explained to someone whose weight kept blowing off with a mostly empty pot:

This is most likely your problem because there is a minimum amount you can load in an All American (probably all canners in fact). Maybe you could add some jars full of water to fill some space and see if that helps.

That is the practical argument against buying more canner than your garden produces. A 941 you fill twice a year and run half empty the rest of the time is a worse tool than a 921 you fill every weekend.

Height: will it clear your range hood?

Here is the fit question almost nobody checks before ordering. The 930 and 941 are both 19 inches tall before you count the pressure gauge and regulator weight sitting on top of the lid, and before you count the clearance you need to lift the lid straight up off the pot and to set the weight on the vent pipe mid-run.

Measure the distance from your burner grate to the underside of your range hood or over-the-range microwave before you buy. No honest guide can tell you a big All American will or will not fit under your hood, because hood heights vary too much; what the published numbers say is that you need 19 inches plus working room above the tallest models, versus 15.375 inches plus working room for the 921. On a lot of ranges that difference is exactly the difference between canning on the back burner and hauling the pot out to a propane burner on the porch.

The 921 and 925, at 15.375 and 16.75 inches, fit under most hoods with room to work. If your only stove is under a low hood or a microwave, that alone can settle the size question.

Weight: do the arithmetic before you buy

The listed empty weights are 22 pounds (921), 23 pounds (925), 25 pounds (930), and 36 pounds (941). Those numbers are only the starting point, and it is worth doing the loaded math explicitly rather than discovering it with your back.

Water weighs a little over two pounds per quart. A full 941 load is 22 quart jars; if you call the contents of each jar roughly what a quart of water weighs, that is about 45 pounds of food alone, before the glass jars themselves and before the several quarts of canning water in the bottom of the pot. Stack it up and a working 941 is in triple-digit territory, sitting on one burner. Run the same arithmetic on the 921, with 22 pounds of pot, seven quarts of food, jars, and water, and you land somewhere in the 40s and 50s: heavy, but one determined person can still move it.

That loaded weight is not just a lifting problem, it is a stove problem. Owners who run All Americans on electric ranges end up engineering around the mass:

I used my AA on an electric coil but I had to buy a canning element which could support that weight.

A canning element rated for the weight, a standalone propane burner, or a reinforced outdoor setup: these are normal accessories for the big models, not edge cases. Budget for them if you are going past the 921.

Glass-top stoves: what All American actually allows

Go to the manufacturer's product pages and read the suitable heat sources line for each model, because it quietly changes as the canners get bigger. The 921 and 925 list gas, electric, and flat-top stoves. The 930 and 941 list gas and electric only; flat-top disappears from the list. And All American's own FAQ is flat about induction: their pressure canners are not compatible with induction cooktops, in any size, because the pot is aluminum.

So on the biggest models the manufacturer has already answered the glass-top question for you: no. On the smaller ones, the community is more cautious than the spec sheet. The standing advice on r/Canning, given to a new 921 owner running trial batches on a ceramic flat-top:

The one real caution is the ceramic flat stove. All American canners are generally not recommended for glass/flat-top ranges, so I’d check both your stove manual and the canner manual before doing actual canning.

Some owners are blunter than that:

No, you cannot use this in a glass top. Buy a propane outdoor burner and can outside.

And the cautionary tales are specific. This one is about a heavy canner on glass, and it is the failure mode that makes the weight arithmetic above worth taking seriously:

I caused my glass cooktop to shatter over a red hot burner by inadvertently sliding a heavy canner on the hot glass. I'm sure the failure was due to a particle of grit scratching the glass combined with thermal stress from the heated burner. The only way to avoid this is if you can absolutely 100% guarantee you will never slide the canner, even a tiny bit, on the glass. I also thought the canner heated up even slower than usual when I was using this cooktop. I switched to a gas cooktop and was much happier.

If you can on a glass-top and still want serious capacity, the honest path is the one glass-top owners keep landing on: a lighter canner rated for the stove, or a standalone burner that takes the stove out of the equation entirely.

You can use a Presto canner that's made for glass top stoves as long as your stove is rated for canners. And many are. But that canner I would only use on a burner with flame. You can buy a separate propane burner to use with it.

The gasketless seal: why people go big with this brand

The reason the size question keeps coming back to All American at all is the metal-to-metal seal. There is no rubber gasket between the lid and the pot: the machined rim is lightly oiled and the wing nuts pull the lid down onto bare metal. Nothing dries out, nothing cracks in storage, nothing needs a part number in ten years. It is the single design decision that turns a pressure canner into a permanent tool, and it is why buying one of these at homestead scale is a once-per-lifetime decision rather than a once-per-decade one.

Congrats, you now have a generational canner. Mine is about 70 years old though. I replaced the vent and gauge and took it to my local extension office to insure it was accurate. I have another brand as well, but this is my work horse.

A seventy-year-old canner still described as the work horse is the durability story in one sentence, and it is the norm for this brand, not the exception. It is also why the price stings less than it looks: the pot does not get bought twice. Owners who paid full freight do not regret it, especially the ones canning meat in volume, which is exactly the workload that justifies a large canner in the first place:

Yes! I bought mine full price, and I love it! Makes canning venison or pork an absolute breeze

Worth knowing on the price front: these have climbed steeply in recent years, and the used market has climbed with them. A 941 owner, on what the big one cost less than a decade ago:

Its crazy how much they have increased in value. I have a 941 I bought in 2016 and they were only $400 back then.

The 941 lists at $649.95 direct today. If a used one crosses your path at a sane price, the seal design means age barely matters; that is the one real discount channel for this brand.

The 921 stock problem

One practical wrinkle with the default answer: the 921 chronically sells out. On Amazon it swings between in stock, a handful left, and gone, and at this writing the listing shows only a few units left. The direct store is steadier but often quotes a ship window rather than same-day shipping (the 941 page currently shows an anticipated ship date measured in weeks, and the 925 and 930 pages show short backorder windows too). None of this is a red flag about the company; it is a small foundry casting a heavy product. But it means the right move is to buy when you see stock, not the week you need to can.

The full case for the 921 itself, including where it frustrates new owners, is in our All American 921 review. The short version: the durability is real, the learning curve and the weight are the honest costs, and availability is the thing that makes people settle for a different canner entirely.

When two smaller canners beat one giant

Here is the math the big-canner brochure never does. Two 921s hold 14 quart jars between them, exactly a 930 load, and you can run them on two burners at once. Each pot stays light enough for one person to lift, fits under a normal hood, and stays on the flat-top-approved list. If one needs a part or a repair someday, you still have a working canner mid-harvest. The pair costs more than one 930, but it buys throughput plus redundancy instead of just volume.

The cheaper version of the same strategy pairs one All American with a budget aluminum canner, and canners arrive at it on their own whenever their main pot is out of commission:

In the meantime, I ordered a new Presto 23 quart to process everything I had. Nothing wrong with having a backup!

A Presto 23-quart runs about a third the price of a 921 and covers overflow batches, a second burner, or a backup during repairs. It uses a gasket and it will not outlive your grandchildren, but as the second canner in a two-pot system it is the obvious value play. Our Presto vs All American comparison covers that tradeoff in full.

And check your actual batch sizes before buying any of this. Plenty of households discover their real canning life is pints of sauce and jam, not 22-quart meat marathons:

Wow... I have the small All American. 7 pints/4 quarts. It is just me, so I don't need quarts to much. Doing tomato sauce now have about 14 pints to process then on to jams and jellies. I am on an electric stove top and have had the weight jiggle issue as well. Haven't run dry...watch it closely.

So which size should you buy?

Buy the 921 if you are most people reading this. Seven quarts a load is a real day of canning, it is the largest model that stays reasonable to lift, fits under most hoods, and keeps flat-top stoves on the approved list. It is the best-selling size of the line for a reason, and the r/Canning consensus prices it honestly:

Buy the All-American even if you have to get a smaller one cause price.

Skip the 925 unless you specifically want more headroom over the same seven-jar load; for most buyers it is $499.95 for the same output as the 921. Buy the 930 if you can quarts in volume on a gas or coil-electric stove, will genuinely fill 14 jars most runs, and have measured your hood clearance. Buy the 941 only for true homestead scale: 22 quarts a load, a gas stove or outdoor burner that can take the weight, and a second set of hands nearby. Both giants are best ordered direct from All American and both may ship on a delay, so order ahead of the harvest, not during it.

Whatever size you land on, remember the processing pressure changes with elevation; check your target pressure with our canning altitude calculator at /tools/canning-altitude-calculator before your first run rather than after a sealed-jar failure.
