If you are comparing presto pressure canner vs all american pressure canner for budget mushroom growing, your decision comes down to the All American 1930: 21.5qt Pressure Cooker/Canner against the Presto 01781 23-Quart Pressure Canner and Cooker. Both are true pressure canners that handle quart jars for grain spawn, yet they approach long term value in opposite ways. One asks you to choose the higher-end pick once for a gasket free design, while the other keeps your upfront commitment low while asking for a little more routine care.
We assessed both units for home mycology use, focusing on jar capacity, pressure control, seal upkeep, and cleanup after grain and substrate runs. For growers watching every dollar, capacity per cycle and replacement parts matter as much as the initial outlay. As with any sterilization gear covered in our Sterilization and Pasteurization guides, 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.

- Weighted regulator plus gauge makes pressure easy to set, hear and maintain
- Heavy-duty USA-made aluminum construction feels solid and long lasting

- Clamp-style lid with multiple knobs has a learning curve compared to twist-lock canners
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.
Pros
- Massive capacity handles large canning jobs in fewer batches
- Versatile 3-in-1 design saves money and storage space
- Fast, even heating from durable heavy-gauge aluminum construction
- Accurate dial gauge ideal for high-altitude canning precision
- Long 12-year warranty and proven reliability from Presto

The Presto 01781 is a 23-quart pressure canner and cooker designed for home canners who process low-acid foods like vegetables, meats, poultry and seafood. It is best suited for gardeners, homesteaders and bulk buyers who need to preserve large batches safely and efficiently.
In real world use, it shines as a true 3-in-1 tool that pressure cans, boiling-water cans fruits and salsa, and cooks meals fast under pressure. The deluxe dial gauge registers the full range of processing pressures, which gives added confidence and control, especially at higher altitudes.
Build quality centers on warp-resistant heavy-gauge aluminum that heats quickly and evenly on regular and smooth-top ranges. Stay-cool handles, a strong-lock steel lid, cover lock system and overpressure plug add layers of safety, while the included rack keeps jars off the bottom for proper circulation.
The tradeoffs are mostly about size and care. This is a tall, wide pot that needs strong stove space and roomy storage, and the aluminum body and lid require gentle hand washing without immersion. The dial gauge is precise but delicate, so it needs careful handling to stay accurate.

How They Compare
Capacity and Jar Layout for Spawn Runs
The All American 1930: 21.5qt Pressure Cooker/Canner holds approx. 19 pint jars or 7 quart jars, which suits growers who run mostly quart grain jars for bulk spawns. The Presto 01781 23-Quart Pressure Canner and Cooker lists room for 26 half-pints, 20 pints, and 7 quarts, so it matches the larger unit on quarts and pulls ahead on pints and half-pints. If your routine centers on quart jars of rye, millet, or oats, both give you the same 7 jar baseline per cycle, so neither forces you to downsize your spawn recipe.
Where the difference shows is when you run smaller jars for agar work, liquid culture expansion, or staggered inoculation schedules that benefit from varied jar sizes. That extra pint capacity in the Presto 01781 23-Quart Pressure Canner and Cooker lets you sterilize a wider mix in one cycle, which saves stove time and energy across a busy inoculation week. You can learn more about planning those smaller runs in our presto 23-Quart vs instant pot for grain jars breakdown, especially if you are still deciding on jar sizes for your first bulk grow.
Pressure Control and Gauge Readability
The All American 1930: 21.5qt Pressure Cooker/Canner features an exclusive precision machined metal-to-metal sealing system with positive action clamping, plus an easy-to-read steam gauge and a precision machined regulator weight for accurate pressure control. In practice, you get a solid and repeatable seal without adjusting a gasket, and the weight gives you clear audible feedback during the cycle. Growers commonly report that this setup feels very stable once you learn the clamping sequence, which helps you hold steady conditions through long grain cycles.
The Presto 01781 23-Quart Pressure Canner and Cooker uses a deluxe pressure dial gauge that registers the complete range of processing pressures, a detail the maker notes is especially important at higher altitudes. That dial makes it simple to monitor small adjustments during grain sterilization, which is helpful if your stove runs hot or your elevation shifts your target. For help judging gauge behavior on a tight budget, see our how to pick a safe spawn canner on a tight budget guide, which walks through what to watch for before you commit to a full load.
Build Quality, Seal Design and Long Term Upkeep
The All American 1930: 21.5qt Pressure Cooker/Canner is built around durability, from the sturdy phenolic top handle to double-thickness edges that add protection on points of heaviest wear, with an easy-to-clean satin finish. Because the seal does not use a gasket, you avoid buying replacement gaskets and you can open and close the cover without stretching rubber parts. The brand presents this as a family-owned, Made in the USA cooker meant to be kept for generations, which aligns with its more premium choice position and its 4.9/5 rating from 9765 reviews.
The Presto 01781 23-Quart Pressure Canner and Cooker is constructed of warp-resistant heavy-gauge aluminum for fast, even heating, and it carries an extended 12-year limited warranty that adds confidence for frequent use. The trade off is routine upkeep, as you will need to keep the sealing surfaces and vent clean and replace wear parts over time to hold a reliable seal. That maintenance is simple and well documented, but it is a real ongoing cost in attention, which helps explain why this model earns a 4.8/5 rating from 20124 reviews while remaining the more accessible choice for growers starting out.
Stove Fit, Ease of Use and Cleanup
The All American 1930: 21.5qt Pressure Cooker/Canner is listed as suitable for gas, electric, or flat top stoves, and the cover is designed to open and close easily once the clamps are set. Cleanup is straightforward thanks to the satin finish and the absence of a gasket channel that can trap grain starch. On the other hand, the unit is heavier and the multi-clamp closure takes a few runs to master, so if you have limited hand strength or a very small kitchen, that heft and learning curve are genuine cons to weigh.
The Presto 01781 23-Quart Pressure Canner and Cooker works on regular and smooth-top ranges and includes a canning and cooking rack plus a complete 76-page instruction and recipe book, so setup feels familiar right out of the box. It doubles as a boiling-water canner for fruits, jams, jellies, pickles and salsa and works as a large capacity pressure cooker, which adds versatility if you also preserve food. After grain work, the lighter aluminum body and rack lift make rinsing and drying quicker, a point we also cover in our presto pressure cooker for grain spawn roundup for growers who sterilize often.
Which One Should You Get
Choose All American 1930: 21.5qt Pressure Cooker/Canner if you sterilize quart jars every week or two and want to minimize replacement parts over many years. You cook on gas, electric, or flat top heat, you have steady storage space, and you prefer a machined metal seal with a regulator weight you can monitor by sight and sound. This is the higher-end pick for growers who would rather invest once and keep the same canner through countless spawn cycles without reordering seals.
Choose Presto 01781 23-Quart Pressure Canner and Cooker if your priority is maximizing sterilizer volume per dollar right now. You run mixed batches of half-pints, pints, and quarts, you want the included rack and detailed instruction book, and you are comfortable with basic seal and vent maintenance between runs. For many first bulk grows, that combination of larger pint capacity, lighter handling, and broad stove compatibility makes it the more practical fit while you build out your lab.
Who Should Skip Both
If you only inoculate one or two small bags a month, work in a space with no suitable stove, or rely solely on pre-sterilized grain, this class of large canner is not ideal for your situation. Both units need dedicated storage, careful venting space, and full attention during pressurized cycles, so they are not a good fit for growers who cannot supervise a long sterilization run. In that case, explore smaller sterilization options in our Sterilization and Pasteurization archive before committing to a 21 quart or larger vessel.
Frequently Asked Questions
Which holds more grain jars, Presto 23-Quart or All American 21.5Qt?
For quart grain jars, they are even, with both rated for 7 quarts per load. For smaller jars, the Presto 01781 23-Quart Pressure Canner and Cooker lists 20 pints and 26 half-pints, compared with approx. 19 pints for the All American 1930: 21.5qt Pressure Cooker/Canner. If you run many pints, the Presto unit gives you more room per cycle.
Is the All American metal-to-metal seal better for long term mushroom growing?
For growers who sterilize often, the metal-to-metal sealing system can lower long term upkeep because there is no gasket to stretch or replace. You still need to keep the metal surfaces clean and follow the clamping steps carefully. If you prefer the lowest upkeep over many years and accept a heavier lid system, many frequent growers favor that design.
Can I use either canner on a flat top or smooth top stove?
Yes, with attention to your stove manual. The All American 1930: 21.5qt Pressure Cooker/Canner is listed as suitable for gas, electric, or flat top stoves, while the Presto 01781 23-Quart Pressure Canner and Cooker is listed for regular and smooth-top ranges. Always confirm weight limits and burner size with your range maker, and keep the canner centered for even heating.
