Best Pressure Canners

Although modern food preservation methods have largely reduced the need for home canning, many people still have an interest in the time-proven practice – especially when faced with a bumper crop of fresh fruits or vegetables. Indeed, many cooks love to create homemade jams, preserves, and soups for themselves or as gifts. Today's pressure canners offer many safety features and design elements that take the fear out of the canning process. We examined dozens of pressure canners/cookers. Here's our shortlist of the models that deliver safe and delicious results every time!

Considerations

Construction/Design

There is some debate among canning enthusiasts about the best construction material for pressure canners. Some believe forged aluminum provides a desirable compromise between strength and heat retention. Others feel that 18/10 stainless steel is a better choice because of its non-reactive qualities and light weight. Our top contenders come from both worlds, and in this section, we explore their pros and cons in terms of safety features, heat retention, and overall strength.

Capacity

Some home cooks like to prepare large batches of canned food; others choose to prepare only a few jars at a time. There's no reason to purchase a high-capacity canner if you only plan to make occasional jam or jelly products. Conversely, those who want to do larger jobs might be disappointed with a low-capacity canner. The total capacity of any pressure canner depends, in part, on the size of the jars and the method of steaming. Low-pressure water baths can only handle one tier of containers, but high-pressure canners can accommodate stacked jars. Each pressure canner on our shortlist has a specific capacity. We discuss those details here.

Overall Performance

Many pressure canners are also promoted as pressure cookers, which means they could be used for speed cooking or steaming as well as canning. Some of our top contenders are equally good at both tasks, but others are significantly better at one job than the other. Pressure cooking, especially with hot oils, can affect the internal surface of a pressure canner and make it more challenging to maintain. In this section, we discuss the versatility and overall performance of each contender on our shortlist.

Price

High-end pressure canners offer the best safety features and, quite often, the highest capacities. However, their advanced engineering and durability tend to make them cost a lot more. Low-end pressure canners are more affordable for those whose canning needs are minimal, but the trade-off is usually a lower capacity or more challenging maintenance. We urge potential buyers to consider their personal canning needs and shop accordingly.

Considerations

Construction/Design

All American 921 21-1/2-Quart Pressure Cooker/Canner

Definitely one of the heavier models on our shortlist, the All American 921 21-1/2-Quart Pressure Cooker/Canner is made of hand-forged aluminum. We appreciate the All American 921's thick walls and exclusive "metal-on-metal," gasket-free connection between the lid and body, but some users may find getting a fully loaded canner to the heat source a bit challenging. In terms of safety, we're happy to report that six bolts keep the lid completely locked down during the canning process. A weighted pressure valve maintains the three most common pressure settings: 5 psi, 10 psi, and 15 psi.

Fagor Duo 10-Quart Pressure Cooker/Canner

While forged aluminum may be the more popular material of choice, the Fagor Duo 10-Quart Pressure Cooker/Canner represents the 18/10 stainless steel school of thought with distinction. One advantage this stainless steel pressure cooker wields over its aluminum counterparts is the fact that it can be used with a magnetic induction burner. It is also light and smooth enough to be used on a glass top stove without scratching. The Fagor Duo's locking mechanism is spring-loaded, and the design includes two separate pressure valves to help release steam quickly. Our only major criticism concerning the Fagor's design is that the pressure settings are limited to a low of 8 psi and a high of 15 psi. In the eyes of many, this makes the Fagor Duo more suitable for pressure cooking than pressure canning.

Presto 01781 23-Quart Pressure Canner and Cooker

The manufacturer states that the Presto 01781 23-Quart Pressure Canner and Cooker is constructed from "warp-resistant, heavy-duty" aluminum, but when stacked against the competition, we're hesitant to put it in the same camp as other, more durable aluminum canners. It is definitely lighter than some contenders (like the All American 921); for some people, this could be a good thing. The Presto 01781's lid is secured by two clamps which also serve as handles. The steam is contained inside the pot by a rubber gasket. The gasket works well enough for most canning projects, but it can be difficult (and expensive) to replace. A pressure valve displays readings up to 30 psi (although 15 psi is often enough for successful high-altitude canning). The valve is not weighted, which may be a consideration for those who are accustomed to older pressure canners with weighted "jigglers" rather than the more modern pop-off valves.

Mirro 92122A Polished Aluminum Pressure Cooker Cookware

The Mirro 92122A Polished Aluminum Pressure Cooker is promoted as a pressure cooker, but potential owners should view it more as a pressure canner. Its polished aluminum construction is ideal for canning projects, but there is some concern about the use of aluminum for pressure cooking because of leaching. (As a pressure canner, the leaching issue is minimized.) We recommend the use of weighted pressure valves in general; the Mirro 92122A has three standard settings controlled by "jigglers:" 5 psi, 10 psi, and 15 psi. An internal rubber gasket helps seal in the pressurized steam, but some users tell us it is not as resistant to water as other gaskets in other models. A sure-lock clamping system, "reusable" over-pressure valve, and gasket venting system improve the Mirro 92122A's safety during high-pressure canning projects.

Granite Ware 0730-2 Pressure Canner, Cooker, and Steamer

If weight is an issue, the Granite Ware 0730-2 Pressure Canner/Cooker/Steamer is clearly a model to consider. Constructed from hard anodized aluminum, the Granite ware 0730-2 can be lifted with one finger when empty. (This doesn't mean it cannot handle settings up to 15 psi, however; it can.) The unit uses a weighted pressure valve system, but there is no pressure dial as such. After 10 minutes of vented steaming, the user applies one or two rings to the pressure valve (depending on altitude) and watches for a gentle rocking motion to indicate that proper pressure has been achieved. While other pressure canner lids often employ rubber gaskets, the Granite Ware 0730-2 uses a more heat-resistant silicone gasket. (The pressure relief valve and other safety features also use silicone gaskets.) We do not recommend this unit for use on glass stove tops or other smooth surfaces. Because it is non-magnetic, the Granite Ware is also not suitable for induction stove tops.

Unlike much of the competition, the Presto 01781's pressure valve can display readings up to 30 psi.
Considerations

Capacity

All American 921 21-1/2-Quart Pressure Cooker/Canner

Some home canning projects call for pint jars; others require quart or even half-gallon jars. The All American 921 can accommodate an impressive 19 pint jars. (It could also handle seven quart jars or four half-gallon jars.) This pressure canner/cooker is also capable of producing a hot water bath for acidic fruits and vegetables. However, the jars cannot be stacked in layers, and the pressure locks must be loosened slightly to avoid high steam pressure. Because the All American 921 is also a pressure cooker, it can be used to prepare large amounts of poultry or other meats. It can also be used to make batches of soup/stew (in less time than a traditional slow cooker).

Among the top contenders on our shortlist, the Fagor Duo 10-Quart Pressure Cooker/Canner clearly has the lowest capacity. We estimate that it can hold a maximum of four pint jars, or perhaps one quart jar, at a time. This is not necessarily a bad thing; the limited capacity would probably be fine for consumers whose canning needs are few and far between. The unit arrives with a steamer shelf (recommended for high-pressure canning). Because of the locking mechanism, however, we're not sure the Fagor Duo is suited for low-pressure hot water baths. Since 18/10 stainless steel is non-reactive, it's likely that this unit performs best as a pressure cooker with the option of small-batch pressure canning.

The Presto 01781's impressive 23-quart capacity is the highest among the contenders on our shortlist. It's estimated that the Presto 01781 can hold seven quart jars or up to 22 pint jars, depending on the stacking configuration. Some experienced canners do not recommend crowding pint jars under high pressure, however, so a maximum of 18 pint jars would reduce the chances of cracking or leaking. If using the hot water bath method for acidic foods, the capacity is closer to seven quart jars on a single level. The Presto 01781 is supposed to arrive with a special shelf for raising jars off the bottom during high-pressure canning, but some users tell us this accessory was not included in their original order. The shelf is important, so we highly encourage users to purchase one separately if it's not included with their purchase.

Mirro 92122A Polished Aluminum Pressure Cooker Cookware

With a total capacity of 16 pint jars (or seven quart jars), the Mirro 92122A Polished Aluminum Pressure Cooker is definitely suitable for larger canning projects. The unit arrives with a flat steamer rack that will suspend the canning jars off the bottom of the pot, allowing steam to circulate above and below the jars. When using the hot water bath method for acidic foods, however, the single-level capacity is closer to seven pint jars. An additional investment in a second steamer rack would greatly improve the stability of the jars during pressure canning. As a pressure cooker, the Mirro 92122A is almost too large for the average pressure-cooked meal. Users could fry chicken or tenderize larger cuts of beef in the Mirro 92122A, but in general, its dimensions and lid design make it more suitable as a dedicated canner.

Although the total capacity of the Granite Ware 0730-2 Pressure Canner/Cooker/Steamer is 20 quarts, the usual practice of stacking jars in two layers does not work with this unit. The pressure canner/cooker arrives with both a steamer basket and a flat canning rack, but canning jars must be placed in a single layer configuration on top of the rack. This means that the Granite Ware can produce a total of seven one-quart jars, eight one-pint jars, or 24 half-pint jars at best. This is still enough space for many typical canning projects, but those who want a dedicated pressure canner for bulk work may be a little disappointed. Because of its generous cooking space and steamer basket attachment, the Granite Ware 0730-2 works equally well as a food steamer and pressure cooker. (Other contenders on our shortlist work better as dedicated canners because jars can be easily stacked, but the Granite Ware pressure cooker/canner/steamer is more of a multi-tasker.)

The All American Pressure Cooker/Canner can accommodate an impressive 19 pint jars.

Considerations

Overall Performance

All American 921 21-1/2-Quart Pressure Cooker/Canner

Although the All American 921 21-1/2-Quart Pressure Cooker/Canner is promoted as both a canner and a cooker, it is most impressive as a dedicated pressure canner. The unit's large capacity and gasket-free design clearly separate it from the rest of the pack. A weighted pressure valve automatically releases steam when the gauge exceeds the proper psi for the user's altitude. The All American 921 can produce steam from most heat sources, but its non-magnetic aluminum construction makes it unsuitable for magnetic induction stoves. Because of the unit's weight, we also caution against use on glass stove tops.

Fagor Duo 10-Quart Pressure Cooker/Canner

Because of its limited capacity, it is somewhat difficult to compare the Fagor Duo 10-Quart Pressure Cooker/Canner's performance to others on our shortlist. Owners have few problems getting the canner's pressure up to the 8-psi mark, but achieving 15 psi can be more of a challenge. The Fagor Duo uses an interior rubber gasket to seal in the pressurized steam, and sometimes that seal is not as strong as users would like. This is one reason why we view the Fagor Duo as primarily a pressure cooker – not a fully realized pressure canner. The unit does cool down quickly, however, which allows for the creation of multiple batches in succession. This is a plus, since there can be a long interim/waiting period with some thick aluminum models.

Presto 01781 23-Quart Pressure Canner and Cooker

Because of its lighter weight, the Presto 01781 23-Quart Pressure Canner and Cooker can be used safely on glass top stoves (unlike heavier models such as the All American 921). While other pressure canners limit pressure options to 5, 10, or 15 psi, the Presto 01781 allows users to make subtle adjustments by changing the heat settings and monitoring the pressure dial. Pressures of 20-30 psi are possible with this unit, although we would not recommend exceeding 15 psi for most canning projects – regardless of altitude.

Mirro 92122A Polished Aluminum Pressure Cooker Cookware

Traditional weighted valve pressure cooker/canners like the Mirro 92122A Polished Aluminum Pressure Cooker have been in production for decades. When used correctly, this unit is reliable and safe. The Mirro's clamps create a strong seal between the lid and pot, but users should still expect some steam to escape through the seams. We wish the internal rubber gasket were a little more durable, but replacements can usually be found in local hardware stores that sell canning supplies. The Mirro 92122A is not magnetic, so it cannot be used on magnetic induction burners. We recommend using the largest burner available when pressure canning, although the Mirro does a great job of generating consistent heat and steady pressure. While it is possible to use a heavy aluminum pressure canner on a glass top stove, owners should avoid sliding the pot across the surface or dropping the pot onto the burner from a height.

Granite Ware 0730-2 Pressure Canner, Cooker, and Steamer

There's a lot to like about the Granite Ware 0730-2 Pressure Canner/Cooker/Steamer, beginning with its versatility and ending with its lightweight design. If owning a multi-tasking pressure cooker is your goal, the Granite Ware 0730-2 is a top model to consider. However, as a dedicated pressure canner, it falls just short of the mark. Pressure canning in bulk takes a considerable amount of time. As such, experienced canners often prefer to prepare as many jars as possible per run. The Granite Ware's limited capacity is a drawback, but in the eyes of some, its steaming and pressure cooking abilities make up for that. From a safety standpoint, the Granite Ware's redundant pressure relief/pop-off valve configuration certainly does reduce the chance of a catastrophic explosion. Indeed, the lid cannot be released until the psi inside the pot is absolutely zero.

The All American 921 21-1/2-Quart Pressure Cooker/Canner's large capacity and gasket-free design clearly separate it from the rest of the pack.
Considerations

Price

All American 921 21-1/2-Quart Pressure Cooker/Canner

The All American 921's retail price of $199 places it at the high end of the pressure canner spectrum, but every penny is "up on the screen," so to speak. Instead of searching for expensive (and elusive) gaskets for bargain-priced pressure canner/cookers, owners of the All American 921 benefit from the exclusive "metal-on-metal" sealing system. Owners needn't rely on a few clamps or locking mechanisms for safety; the All American 921's six solid bolt locks keep the steam inside the chamber. What's more, the ability to process up to 19 pints (or seven quarts) of canned food at once represents a savings of both time and energy.

Fagor Duo 10-Quart Pressure Cooker/Canner

As a combination pressure cooker/canner, the small-capacity Fagor Duo's retail price of $119 might seem a little high. Then again, those customers who have very modest canning needs might find it to be the perfect size. The Fagor Duo is made of 18/10 stainless steel, a premium material for kitchen appliances and the best choice for home cooks who prefer magnetic induction burners. Two separate "over pressure" relief valves make this unit exceptionally safe, and the non-reactive pot is machine washable. While the price may be higher than some aluminum-based canners, the Fagor Duo's smooth interior walls will not retain impurities such as used vegetable oil and rendered fat. This is an important consideration when shifting from pressure cooking to pressure canning.

Presto 01781 23-Quart Pressure Canner and Cooker

At a retail price of $76, the Presto 01781 23-Quart Pressure Canner and Cooker would be a great choice for those who want to take on larger canning projects without investing in commercial-grade equipment. It has all the capacity of high-end pressure canners/cookers as well as a great safety record. The 12-year limited warranty is nice, too! Some other pressure canners can be extremely heavy and difficult to maneuver, but the Presto 01781 is light enough to use on a glass top stove without fear of damage. Our main concern about the Presto 01781 is the cost of replacing its rubber gasket. Satisfied owners tell us, however, that the original gasket should provide years of service before that day arrives.

Mirro 92122A Polished Aluminum Pressure Cooker Cookware

The $53 Mirro 92122A Polished Aluminum Pressure Cooker is definitely tempting for home cooks who seek a dedicated pressure canner with a large capacity. Entry-level pressure canner/cookers often lack the ability to hold more than four or five jars. Pricier pressure canners (like the All American) often take a long time to heat up and cool down. Investing in a mid-range model like the Mirro 92122A is a smart and economical compromise between those worlds. While we have some reservations about its suitability as a pressure cooker, we highly recommend the Mirro 92122A Polished Aluminum Pressure Cooker as a dedicated canner for home cooks who are new to the world of canning but anticipate making large batches of jams, jellies, stews, and other delicious treats.

Granite Ware 0730-2 Pressure Canner, Cooker, and Steamer

With a low retail price of $99. the Granite Ware 0730-2 Pressure Canner/Cooker/Steamer is among the most affordable of our top pressure canner contenders. Consumers who want a competent multi-tasker that can perform three different kitchen chores equally well should be satisfied with the Granite Ware 0730-2. The cost of purchasing a separate vegetable steamer, pressure cooker, and pressure canner would be considerable, so we recommend this product as a culinary "jack-of-all-trades." It may not be at the same level of performance as some of our higher-end contenders, but it will handle modest canning and pressure cooking tasks with ease.

The Presto 01781 23-Quart Pressure Canner and Cooker is a great choice for those who want to take on large canning projects without paying a commercial-grade price.

Best of the Best

The ideal pressure canner strikes a perfect balance between safety, performance, and capacity. All of our top pressure canners are capable of performing at that level, but one model stands out for its superior attention to detail. That model is the All American 921 21-1/2-Quart Pressure Cooker/Canner.

This commercial-grade unit uses a total of six locking bolts to achieve a strong, metal-on-metal seal. This seal is crucial when you have a highly pressurized cooking vessel sitting exposed on a stove top burner! Other pressure canners use rubber or plastic gaskets to form their seals, but those gaskets can wear out over time and are often difficult to replace.

When it comes to canning food, failure is not an option. The final product needs to be properly sterilized for safe storage and consumption.The All American 921's automatic release valve is designed to pop off whenever the internal pressure exceeds the selected 5-, 10-, or 15-psi setting. What's more, the unit's hand-forged aluminum construction means thicker walls for better heat retention and extra strength. Indeed, the $199 All American Cooker/Canner is more expensive than some other units on today's market, but you get what you pay for in terms of quality and peace of mind.

The All American 921 has the high capacity and durability professional cooks covet. And yet, it's sold at a retail price that amateur home canners can afford. For all of these reasons, we declare the All American 921 21-1/2-Quart Pressure Cooker/Canner to be the Best of the Best!

Best Bang for your Buck

Capacity, reliability, and safety are all important considerations when shopping for a pressure canner. Because it can take several hours before a pressure canner is ready for the next batch, users need to be able to process as many jars as possible per canning session. Having a reliable pressure gauge and effective pop-off valve is important from a safety point of view. One of our top pressure canners provides this level of performance and safety without the accompanying price tag of commercial-grade equipment. That product is the Presto 01781 23-Quart Pressure Canner and Cooker.

Experienced home canners know that different projects respond better to different psi settings. The Presto's unweighted pressure dial allows users to make their own psi adjustments by controlling the heat source itself. All of the safety features still work as designed, but users have the freedom to maintain a specific psi level throughout the canning process. This flexibility makes the Presto, at a cost of just $76, a sweetheart of a deal.

Beginning home canners have commented that the Presto's straightforward design and minimalist approach are very helpful as they learn the art of canning. Should there be any problems with the unit, Presto's 12-year limited warranty serves as a reassuring cushion for consumers. What's more, owners enjoy the fact that this unit functions equally well as a pressure canner and pressure cooker. If you're looking for a quality canner that delivers the goods economically and safely, we urge you to consider the Presto 01781 21-Quart Pressure Canner and Cooker – the Best Bang for Your Buck!
