The All American 921 is a 21.5-quart stovetop pressure canner and cooker designed for serious home preservers. It is ideal for gardeners, homesteaders and families canning low-acid foods like meat, beans and vegetables in pints or quarts.
Its standout metal-to-metal seal locks steam-tight with positive clamping and no gasket to wear out. In real use, owners report fast sealing with a light oil on the rim, steady pressure from the regulator weight, and the gauge as a handy visual reference.
Built in the USA from heavy cast aluminum, it features double-thickness edges, a sturdy phenolic handle and a smooth satin finish. The steam gauge, regulator weight and clamping knobs feel precise, rugged and made to serve for decades.
The tradeoffs are size and weight, since it is tall, bulky and heavy when fully loaded. New users also need practice to evenly tighten the clamps and manage heat for stable pressure.
For anyone committed to safe, high-volume home canning, the 921 is a buy-it-for-life workhorse. It is durable, versatile and dependable enough to pass down through generations.
Model 921 with 21.5-quart capacity, holds approximately 19 pint jars or 7 quart jars. Dimensions are 12.25 inches by 12.25 inches by 15.37 inches with a weight of 20 pounds.
Material is cast aluminum with satin finish, phenolic top handle and double-thickness edges for added strength. Closure uses positive action clamping locks with precision machined metal-to-metal seal.
Controls include easy-to-read steam gauge and precision machined regulator weight for accurate pressure control. Compatible with gas, electric and flat top stoves.
Choose the 21.5-quart size if you can in full quart batches or large garden harvests without constant reloading. Smaller households or beginners may prefer a smaller model for easier lifting and storage.
Confirm stove fit before buying, as you need a sturdy burner, vertical clearance for the tall lid and gauge, and ability to support a heavy fully loaded pot. Always vent steam as directed, then bring to pressure and adjust heat to keep the weight gently rocking.
Maintain the seal by keeping the rim clean and lightly oiled, tightening knobs evenly, and keeping the vent pipe and gauge clear. With basic care, this gasket-free design avoids replacement parts and stays reliable for years.

How They Compare
Capacity and Jar Layout for Grain Jars
All American 1930: 21.5qt Pressure Cooker/Canner is listed to hold approx. 19 pint jars or 7 quart jars, while Presto 01781 23-Quart Pressure Canner and Cooker is listed for 26 half pints, 20 pints, and 7 quarts. For you as a grower, that means quart capacity for grain is tied at 7 quarts, while the Presto listing shows more room for pints and half pints. If you run many small jars for agar work and culture expansion, that extra pint space could streamline your weekly cycle, as discussed in our Presto vs Instant Pot for grain jars breakdown.
In practice, both All American 1930: 21.5qt Pressure Cooker/Canner and Presto 01781 23-Quart Pressure Canner and Cooker will handle a solid load of quart grain jars for monotub spawns, and both include rack style support for safe stacking. The difference is workflow rhythm rather than raw quart count. Growers commonly report the All American vessel feels heavier to lift and move when loaded, which could slow you down if you sterilize often in a small kitchen. The Presto vessel is often described as easier to load and unload for frequent pint runs, though you will need to be more careful with lid alignment and seal care.
Pressure Monitoring and Control Precision
Control feel is where All American 1930: 21.5qt Pressure Cooker/Canner and Presto 01781 23-Quart Pressure Canner and Cooker diverge for sterile technique. The All American model features an easy to read steam gauge plus a precision machined regulator weight for accurate pressure control. The Presto model features a deluxe pressure dial gauge that registers the complete range of processing pressures, which the maker notes is especially important at higher altitudes. If you live at elevation, that full range dial readout could give you added confidence when following recipes.
For daily use, All American 1930: 21.5qt Pressure Cooker/Canner offers a more tactile, weight based rhythm that many long term canners prefer once they learn the rocking pattern. Presto 01781 23-Quart Pressure Canner and Cooker leans more visual, with the dial as your main reference during heat up and processing. The con side is real for both. Dial gauges demand careful reading and routine care per the manual, while regulator weights demand attention to sound and movement. Beginners who get distracted easily might find either system fussy until the routine becomes habit.
Seal Design, Build Quality and Long Term Upkeep
Build philosophy separates All American 1930: 21.5qt Pressure Cooker/Canner from Presto 01781 23-Quart Pressure Canner and Cooker more than any other factor. The All American unit uses an exclusive precision machined metal to metal sealing system with positive action clamping that forms a steam tight seal without any costly to replace gaskets. It also highlights double thickness edges on points of heaviest wear, a sturdy phenolic top handle, and Made in the USA casting from a family owned company. Owner ratings reflect that reputation, with 4.9 out of 5 from 9765 reviews.
By contrast, Presto 01781 23-Quart Pressure Canner and Cooker is constructed of warp resistant heavy gauge aluminum for fast, even heating and carries an extended 12 year limited warranty, with a rating of 4.8 out of 5 from 20124 reviews. The listing for All American 1930: 21.5qt Pressure Cooker/Canner emphasizes no gasket replacement, while the Presto listing emphasizes light aluminum construction and value focused upkeep. That creates clear tradeoffs. The All American lid needs careful alignment and occasional sealing surface care, and the unit is the higher end pick to acquire. The Presto body needs gentle cleaning to protect the aluminum and routine seal inspection per instructions, which you can learn more about in our guide on how to tell if a canner is safe for spawn.
Stove Compatibility, Handling and Cleanup
On the stove, All American 1930: 21.5qt Pressure Cooker/Canner is listed as suitable for gas, electric, or flat top stoves and features an easy to clean satin finish plus a cover that opens and closes easily because there is no gasket to drag. Presto 01781 23-Quart Pressure Canner and Cooker is listed to work on regular and smooth top ranges and includes a canning and cooking rack plus a complete 76 page instruction and recipe book. Both double as more than sterilizers, with the Presto specifically listed to double as a boiling water canner and large capacity pressure cooker. Always follow the manufacturer’s own instructions for your specific unit, never leave it unattended while pressurized, and let the pressure release naturally before opening the lid.
For cleanup, All American 1930: 21.5qt Pressure Cooker/Canner has the edge in simplicity because the satin finish wipes down and there is no gasket channel to scrub, though the metal to metal rim must stay clean and nick free to seal well. Presto 01781 23-Quart Pressure Canner and Cooker heats fast and evenly thanks to the heavy gauge aluminum, but aluminum needs non abrasive care and thorough drying to avoid discoloration. If you process grain weekly, consider sink size and storage too. Both are tall, wide vessels that dominate a burner and need full cool down space, which could frustrate you in a tight galley kitchen.
Which One Should You Get
Choose All American 1930: 21.5qt Pressure Cooker/Canner if you want a buy once sterilizer for years of quart jar grain work and you like the idea of never ordering a replacement gasket. You run 5 to 7 quart jars per cycle for bulk monotub grows, you have a sturdy gas, electric, or flat top stove with room to store a heavy vessel, and you do not mind learning lid clamping and gauge reading. This is the more premium choice and the higher end pick for growers building a long term home lab who value USA casting, double thickness edges, and a phenolic handle that feels solid during every run.
Choose Presto 01781 23-Quart Pressure Canner and Cooker if you want maximum pint and half pint flexibility with lighter handling and helpful starter materials. You run mixed loads of 20 pints or 26 half pints for culture jars, small grain trials, and liquid culture expansion, you appreciate the included rack and 76 page book for step guidance, and you want the reassurance of an extended 12 year limited warranty. This option suits beginners and budget minded growers who sterilize often and prefer easy lifting, as we outline in our Presto picks for grain spawn on a budget.
Who Should Skip Both
Large stove top canners are not ideal for every grower, and both of these models are not a good fit if you only sterilize one or two jars at a time or you lack a full size burner and safe cool down space. They are also not recommended for growers who need a set and forget electric unit, who live where open stove top canning is restricted, or who primarily buy pre sterilized spawn bags and only need pasteurization for bulk substrate. In those cases, a smaller cooker or a focus on pasteurization gear will save space and hassle.
