The short answer
Buy the Presto 01781. It is 23 quarts, it takes 7 quart jars or 20 pintsin a load, Presto publishes a 12-year limited warranty on it, and its gauge reads the full range of processing pressures — so you can follow a USDA process by the number instead of by feel. It is also a working boiling-water canner, which saves you a second pot. Buy the All American 921 if you intend to can for decades: it is cast in Wisconsin and sealed metal-to-metal with no gasket, so the one part that perishes on every other canner does not exist on this one. Buy the Presto 01755if the 23-quart pot will not fit your cupboard or your back burner — it still takes 7 quart jars, and nothing about the process changes. Buy the Presto Precise digital canner only if you have no usable cooktop or no confidence with an altitude table: it holds the processing temperature with a sensor and needs no altitude adjustment, and it costs that convenience in warranty, from twelve years down to one.
And the pick that is not on this page: your multicooker. If you came here looking for an Instant Pot that cans, read why you should not use one for low-acid food before you buy anything at all.
Why this category gets its own rules
Every other roundup on this site is about whether dinner comes out well. This one is about Clostridium botulinum, and that changes how a page like this has to be written. Presto puts the position on its own canner pages in one sentence: Pressure canning is the only method recommended safe by the U.S.D.A. for low-acid foods such as vegetables, meats and fish.
Low-acid food held in a sealed jar at the wrong temperature is the textbook environment for botulinum toxin, and the only domestic equipment that reliably destroys the spores is a pressure canner running a validated process. Boiling water will not do it. A hot oven will not do it. A pressure cooker that cannot be vented and cannot show you its pressure will not reliably do it either.
The number everything turns on is published by the National Center for Home Food Preservation, the USDA-funded body whose processes every canning recipe in the United States is written against: At sea level, a canner operated at a gauge pressure of 10.5 lbs provides an internal temperature of 240°F.
That is the target. Reaching 240°F is what a canner is for, and the three structural requirements below are what make reaching it verifiable rather than hopeful.
How we ranked them
Entry requirement, applied before price or brand was looked at: the pot must satisfy the NCHFP description of a pressure canner. That rules out almost everything the search engines will show you alongside this page.
- Enough volume to hold real jars. NCHFP describes canners as units that hold
seven quart jars or eight to nine pints
, with small canners holding four quart jars, and then states the exclusion plainly: Pressure saucepans with smaller volume capacities are not recommended for use in canning.
A four-quart-jar load is the floor. All four canners here publish 7 quart jars per load, which clears it comfortably. - A processing pressure you can actually hold and read. Either a dial gauge that shows you the pressure, or a weighted regulator that jiggles or rocks at a known pressure. NCHFP's rules differ by type, and both rules are real work: dial gauges need to be
check[ed] for accuracy before use each year
and replaced if they are more than 2 pounds out, while weighted gauges cannot correct precisely for higher elevations
and must be run at 10 psi instead of 5, or 15 instead of 10, above 1,000 feet. - A vent you can hold open for ten minutes. NCHFP:
To be safe, all types of pressure canners must be vented 10 minutes before they are pressurized.
Ten minutes of steam out of an open vent purges the air, because trapped air makes the gauge read a pressure the food inside is not actually at. A cooker that seals automatically and vents on its own schedule cannot be made to do this. - Then, and only then: documentation quality, build, serviceability, and price. Which is why the cheapest canner on this page is third and the dearest is second.
As everywhere on this site, we have canned nothing in these pots. Every figure below is quoted from Presto's or All American's own product pages or from NCHFP, cited on each card, and every pick carries a real disqualifying reason to skip it. The full rubric is in our methodology. Prices move, so they are not printed in prose — the live price sits on each card.

1. Presto 01781 — the default, and the right first canner
There is a reason this is the canner in most American basements. Presto publishes everything that matters on one page: 23 quarts of liquid capacity, a Mason jar capacity of 26 half-pints, 20 pints, or 7 quarts, a body of extra-strong, warp-resistant aluminum
, a design limit of household range burners of 12,000 BTUs or less
, and an extended 12-year limited warranty. The gauge reads the full range of processing pressures, the air vent and cover lock keep the lid shut until pressure has safely dropped, and the pot doubles as a boiling water canner for fruits, jams, jellies, pickles and salsas
. For most people that last line quietly replaces a second large pot.
Twenty pints per load is the specification that earns it first place. A canning session is not a 90-minute wait, it is 90 minutes of attention — vent, pressurize, hold, cool, check seals — so halving the number of sessions is worth more than any price difference on this page. Against the All American, the Presto holds two more pint jars for roughly 40% of the money.
Three honest limits, and the first one costs people real money. Presto lists this canner for regular and smooth-top ranges, not induction. The induction-compatible version is a different stock number (01784) with a stainless-clad base, and buying the 01781 for an induction hob leaves you with a pot that will not heat — if your cooktop is induction, start from which pressure cookers work on induction and buy the 01784 instead. Second, it is a dial gauge, so NCHFP's annual accuracy check applies: an errand, every year, forever. Third, aluminum discolors, and some glass-top manufacturers advise against heavy aluminum canners on their surfaces — check your own cooktop manual, not ours.
2. All American 921 — no gasket, no consumable, no argument
The All American is here for one engineering decision. Where every other canner on this page squeezes a rubber gasket between lid and pot, the 921 uses a precision machined metal-to-metal seal
and no gasket at all. The part that dries out, stretches, and goes missing in the drawer between seasons simply does not exist. It is cast aluminum, made in USA (Wisconsin)
, it holds 21.5 quarts and 18 pint jars or 7 quart jars, and it carries both a regulator weight set to 5, 10, or 15 PSI
and a geared steam gauge
— the only lid here that gives you the weight's self-regulation and a readable pressure at the same time. All American publishes the interior diameter (12 1/4 in), the interior depth (10 1/2 in) and the 24-pound empty weight, and keeps a parts compatibility table reaching back to units sold before 1978.
That dual regulator is genuinely useful rather than a spec-sheet flourish. Run the weight and the canner holds its own pressure mechanically, which is the failure mode that matters when the phone rings mid-process; glance at the gauge and you can still see what it is holding. If you live above 1,000 feet, NCHFP's weighted-gauge rule — 10 psi instead of 5, 15 instead of 10 — applies here, and this is the one canner where you can watch the gauge confirm that the weight is doing what the table says.
Now the reasons it is second and not first. The warranty is 1 year limited, against Presto's twelve, on the most expensive pot here — a genuinely strange specification to publish on a product sold as buy-it-for-life. It is 24 pounds empty, and All American itself says to add 20 to 30 pounds for water and jars, which is a two-handed lift onto a back burner that some buyers simply will not manage. It holds two fewerpints per load than the cheaper Presto. It is not induction compatible. And the machined lid wants a film of oil on the sealing faces with the clamps tightened in sequence — a ritual, not a hardship, but real. Note too that the manufacturer's own store page has shown this model on backorder with a late-November 2026 ETA even while Amazon has had stock; the card above prices the Amazon listing, which is the one we verified.
3. Presto 01755 — the same process in a smaller pot
The 16-quart Presto exists for a specific and very common problem: the 23-quart canner is too tall for the cupboard, too heavy at the sink, or too wide for the only burner that can take it. Presto publishes 16 quarts (15.1 liters), a jar capacity of 13 half-pints, 10 pints, or 7 quarts, the same extra-strong aluminum
body, the same 12,000-BTU burner limit, and the same extended 12-year limited warranty. The important thing about that jar table is what is unchanged: 7 quart jars, exactly as many as the 23-quart canner. If you can quarts — tomatoes, stock, soup, whole chicken — this pot has the same throughput as the big one.
It is third rather than first because of the other half of that table. Ten pints a load against twenty means double the sessionsfor pint and half-pint work, which is most of what most people actually can: beans, carrots, jams, salsa. Presto also notes that the pint and half-pint counts apply to the boiling water method, so read the jar table against the method you are running rather than assuming it transfers. Beyond that it inherits every limitation of its larger sibling — dial gauge and its annual check, aluminum body, regular and smooth-top ranges only, no induction.
Buy it for its height and weight, not for its price. The saving over the 01781 is small, and the difference in how many evenings a harvest takes is not.
4. Presto Precise 23-quart digital canner — for people without a burner
This machine takes the two steps home canners get wrong — holding the pressure steady and adjusting the process for altitude — and moves them into software. Presto publishes 23 quarts (21.8 liters), 120 Volts AC, 1100 Watts, both pressure canning and boiling water canning, a sensor that holds the required temperature automatically, with no altitude adjustments needed
, jar preheating, and ten built-in safety features including a cover locking system
. It runs off a countertop outlet, which makes canning possible on an induction hob, on a burner that exceeds Presto's own 12,000-BTU stovetop limit, or in a kitchen with no stove at all.
It also contains the most honest sentence any canner manufacturer publishes, and it is worth quoting properly. Presto calls these the first digital pressure canners that meet USDA home canning guidelines
and prints standard USDA processing times in the instruction book — and then states in its own footnote that neither the USDA nor the National Center for Home Food Preservation certifies or approves home canning equipment.So “meets USDA guidelines” is Presto's claim about Presto's processes, not an agency approval of the hardware. That distinction is exactly why this machine is on this page and a multicooker with a “canning” button is not: Presto designed to the published processes and says so in writing, and then tells you who did and did not bless it.
The costs are real. The warranty drops from twelve years to one, on a machine that costs roughly twice the stovetop 01781. It is electronics inside a steam appliance: a failed sensor or control board ends your season, where the worst failure on a stovetop Presto is a gasket you order for pocket change. Presto publishes no body material for it, where both stovetop canners state theirs. And the 1,100 W element is fixed, so you cannot turn the heat up to shorten the come-to-pressure stage. If you own a working gas or smooth-top burner, the stovetop canner is the better buy on every axis except convenience.
The pressure cooker you already own
The query that brings most people to this page is “best pressure cooker for canning,” and the honest answer is that the two phrases describe different machines. We wrote pressure cooker vs pressure canner to lay out the equipment difference in full, and pressure canning in an Instant Pot to answer the specific question about electric multicookers against NCHFP's own position. The short version: NCHFP's recommended-canner guidance excludes smaller-volume pressure saucepans outright, requires a ten-minute vent that a self-sealing electric cooker cannot be made to perform, and requires a pressure you can verify. An appliance that cannot do those three things is not made safe by a button labeled “canning.”
None of which makes a multicooker useless here. It is excellent at everything canning is not — stock and bone broth to freeze rather than shelf-store, dried beans in 40 minutes instead of a day, and tough cuts made tender. If you want a cooker rather than a canner, the ranked list is the best electric pressure cookers, and the stovetop equivalents are in the best stovetop pressure cookers — where the Presto 01362 and the Kuhn Rikon Duromatic are the same engineering tradition as the canners above, at a fraction of the volume.
What we would buy
First canner, any household: the Presto 01781, for 20 pints a load and a 12-year warranty. Canning for the next thirty years: the All American 921, for the gasket that does not exist. Small kitchen, quart jars: the Presto 01755, which gives up pints and nothing else. Induction hob, or no stove at all: the Presto Precise 02153, accepting one year of warranty in exchange for never reading an altitude table.
Five questions to settle before you buy a canner
What is under the pot? This is the first question, not the last, and it eliminates options faster than price does. Presto designs its stovetop canners for household range burners of 12,000 BTUs or less
and lists them for regular and smooth-top ranges. If your hob is induction, you need the 01784 rather than the 01781, or an electric canner. If you have a high-output gas burner, you are above Presto's design limit and will be running it turned down. If your cooktop is glass, read your cooktop manual: several makers discourage heavy aluminum canners on their surfaces.
Quarts or pints? The jar tables diverge far more than the liquid capacities suggest. All three 7-quart-jar canners here are identical for quart work. For pints, the 23-quart Presto takes 20, the All American 18, the 16-quart Presto 10. Count the jars you filled last season, divide, and you have the number of evenings each option costs you.
Dial or weight? A dial gauge shows you a number and NCHFP wants it checked for accuracy annually, replaced if it is more than 2 pounds out. A weighted regulator cannot drift, because it is a lump of metal, but NCHFP warns it cannot correct precisely for higher elevations
and must be run a step up — 10 psi instead of 5, 15 instead of 10 — above 1,000 feet. Neither is better in the abstract. The dial suits someone near sea level who will keep the appointment; the weight suits someone at altitude, or someone who will not.
How high do you live?Altitude is not a footnote in canning, it is the process. Water boils cooler as you climb, so the same gauge pressure delivers a lower internal temperature, and the whole point is 240°F. Look up your elevation before you choose a gauge type, and if the answer is well above 1,000 feet, either commit to the altitude table or buy the canner that handles it for you.
Where will the recipe come from?The pot is the cheap part. Every process you run should come from a tested source — the NCHFP process tables, your state extension service, or the instruction and recipe book Presto and All American ship in the box. A canner running an untested family recipe for a low-acid food is not safer than no canner at all, and no amount of hardware fixes that. If you are starting out, how to use a pressure cooker covers the mechanics of venting and pressure that canning then builds on.
