Presto 01781 23-Quart Pressure Canner and Cooker
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
Cons

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.
Overall, the Presto 23-quart remains a benchmark for home canning thanks to its huge capacity, versatility and long warranty support. If you want one reliable vessel for big canning days and everyday pressure cooking, this is an excellent pick.
Capacity: 23-quart liquid capacity, 21.8 liters, holds 26 half-pints, 20 pints, 7 quarts.

Construction pairs heavy-gauge aluminum with a stainless steel clad base for fast heat distribution and easier handling than heavier steel canners. The cover lock, air vent and visual pressure indicator add confidence, while the included rack and 80-page instruction book simplify setup.
The size is the tradeoff, as it needs strong stove support and roomy storage. It ships with only a basic rack and standard regulator, so many buyers add a jar lifter and adjustable weight set for more flexibility, and compatibility with some portable induction units can vary.
Overall, this is one of the most versatile and beginner friendly full-size canners available. If you want safe, USDA recommended canning with true multi-stove freedom and large batch efficiency, the Presto 01784 is an excellent long term investment.

The Presto Precise 02152 is a 17 quart digital pressure canner built to make home canning automatic and stress free. It is ideal for beginners, busy homesteaders and high altitude users who want safe, consistent results without watching a gauge.
Its standout feature is the innovative temperature sensor that locks in the exact processing temperature and auto detects boiling point for water bath canning. The digital interface lets you pick the method and time, then preheats jars, holds them ready, and runs the built in timer for you.
Build quality feels sturdy with a stainless steel body, buckle closure and removable ceramic coated pot that is PFAS free. The touch controls, LED step icons and 10 built in safety features including cover lock give added confidence during every batch.
The tradeoffs are size and power, as it weighs 24.3 pounds, stands 18 inches tall and needs a dedicated 120 volt outlet. Batch size is also modest at 5 quarts, so very large gardens will require multiple runs.
Overall, this is one of the easiest and most reliable electric canners for safe home preserving. If you want guided, hands off canning for quart jars at any altitude, it is an excellent upgrade from manual stovetop models.
Capacity: 17 quarts. Pressure canning holds 5 quarts, 8 pints, 19 half pints. Boiling water canning holds 5 quarts, 8 pints, 10 half pints.
Power and controls: 1485 watts, 120 volts, automatic operation with touch push button controls, LED display and built in timer.
Dimensions and build: 14.5 inch D x 17.25 inch W x 18 inch H, 24.3 pounds, stainless steel finish with removable PFAS free ceramic coated pot.
In the box: digital canner base, ceramic pot, stainless steel canning rack, instruction and recipe book based on USDA guidelines, quickstart guide.
Choose this digital canner if you are new to canning, can above 1,000 feet, or want set and forget convenience. The automatic sensor and step guides remove the need for manual pressure adjustments.
Consider a large stovetop canner if you process huge batches every harvest or need to use a gas stove off grid. This electric model needs counter space and standard household power.
For best results, use standard mason jars, follow the included USDA based times, and allow room for preheating and cooling in your canning schedule.
Pros
- Large capacity ideal for big batch preserving
- Truly complete kit with rack, lid and all essential hand tools
- Beginner friendly with clear step-by-step manual
- Sturdy utensils built for repeated home canning use
- Organized storage box keeps set together between seasons
Cons
- Large 14 x 19 inch footprint needs ample stovetop space and storage room

The SupaAnt 23 Qt Canning Pot with Starter Kit is a water bath canning system designed for home preservers who want to start right away. It is best suited for beginners and batch canners making jam, pickles, sauces, salsas and stews.
Standout features include the extra large 23 quart pot, fitted wire rack and full tool set with jar lifter, funnel, magnetic lid lifter, bubble remover, jar wrench and XL ladle. In real world use, the large capacity reduces the number of batches while the rack improves water circulation for more even processing.
Design focuses on practicality, with a lidded pot, canning base and sturdy utensils built for repeated use. The bright green fluorescent tools are easy to spot in a drawer, and the included storage box plus instruction manual keep the whole setup organized and beginner friendly.
Drawbacks center on size and handling, as the pot measures 14 x 19 x 14.5 inches and weighs 17.4 pounds before water and jars are added. You will need a large burner, sturdy stovetop and dedicated storage space, and the bold color choice will not suit traditional kitchen tastes.
Overall, this is a convenient all in one solution for anyone getting into water bath canning. If you want large capacity, complete tools and clear guidance in one box, the SupaAnt kit is a strong pick for starting or upgrading your preserving setup.
Brand: SupaAnt, Model: Complete Canning Kit, Capacity: 23 quart pot with lid, rack and canning base. Dimensions: 14 x 19 x 14.5 inches, Weight: 17.4 pounds.

The tradeoffs are size and manual operation. It needs a powerful gas burner and generous storage space, and beginners will need practice to monitor pressure, lock the lid and vent steam correctly.
Overall, this is a practical, large capacity workhorse for home canning and pressure cooking. If you want a gas compatible canner for bulk preserving with standard mason jars, the Barton 23 quart is a strong fit.

Real world performance centers on speed and capacity. It cooks staples like beans, meats and stews much faster than standard pots while keeping flavor rich. Users praise its practical size, quick results and usefulness for daily cooking.

Pros
- Large 24 quart size ideal for big batch preserving
- Includes all essential beginner tools, no extra purchases needed
- Clear gauge and triple safety system for peace of mind

- Manual operation and gauge monitoring may have learning curve for complete beginners
The kilogorge 24Qt Pressure Canner is an aluminum batch canner bundled with a 7 piece starter kit, built for home preservers handling seasonal produce, meats and seafood. It is a smart pick for novices who want everything in one box and for intermediate canners upgrading to larger batches.
In real use, the 24 quart capacity shines by holding multiple jars at once and cutting total processing time versus small cookers. The easy to read gauge keeps pressure visible throughout, while the fixed 14.5 PSI setting delivers strong, consistent results for low acid foods, steaming and simmering.
Design centers on practicality with a smooth green aluminum body, flat composite base and manual push button operation. The flat bottom heats evenly on gas, electric and induction cooktops, and at 6.8 kg it is manageable to lift, fill and clean for its size.
There are tradeoffs to note. It runs at 14.5 PSI by default, so cooks needing 10 PSI must order the separate three level regulator. Aluminum also requires gentler care than stainless steel, and first time users will need a little practice with venting, locking and gauge reading.
Overall, this kit offers excellent value for anyone starting or scaling home canning with a versatile, safety focused setup. If you want large capacity, full tools and multi stove compatibility in one package, this green 24 quart model is worth considering.
Brand: kilogorge, Capacity: 24 quarts, Material: Aluminum, Color: Green, Finish: Smooth.

- Compatible with gas, induction, electric and ceramic stoves
- Heat resistant handles for safer handling of large loads
Cons
- Heavy 20.5 pound build can be difficult to lift and store when full
- Not dishwasher safe, so the large 22L pot requires hand washing
- Bulky 13.39 x 16.34 inch size needs ample stovetop and storage space

Operating at 60Kpa with a sealed outer lid and triple layer composite bottom, it builds pressure quickly and holds heat evenly for consistent results. In real world use, this setup helps retain flavor and texture while significantly shortening cook times for tough cuts and dried legumes.
The body is made from polished 201 stainless steel with a reinforced structure rated to 150C for repeated high temperature cooking. Dual heat resistant side handles, spring valve, pressure limiting valve and anti blocking lid system add control and stability during operation on gas, induction, electric and ceramic stoves.
The tradeoffs are size and weight, as the 20.5 pound pot measures over 16 inches tall and needs generous stove and storage space. It is also not dishwasher safe, so hand washing this large vessel takes extra effort.
Overall, this Eapmic pressure canner is a practical pick for anyone prioritizing capacity, versatility and simple safety features over compact convenience. If you regularly cook for a crowd or run a small food operation, its large volume and multi stove design offer strong utility.

Buying Guide: What Home Growers Should Compare
Choosing a canner for mushrooms is different from choosing one for green beans. You need tall clearance, repeatable pressure and a rack that keeps jars off direct heat. The notes below show what we prioritize for grain, agar and substrate jars in 2026 so you can match a model to your stove and batch size.
Capacity and Jar Layout for Grain Spawn
You want quart jars to stand upright with water below the lids and steam circulating freely. The Presto 01781 23-Quart Pressure Canner and Cooker holds 7 quarts, 20 pints or 26 half pints, and includes a canning rack plus instruction book. That layout lets you sterilize enough rye or millet for a full 54Qt monotub setup in one run instead of stacking risky back to back cycles.
Extra tall models help even more when you run mixed loads. The Presto 02153 23-Quart Digital Pressure Canner also holds 7 quart jars for pressure canning and boiling water use, which suits growers who preserve broth and agar media together. Avoid confusion with the 23 Qt Canning Pot with Canning Supplies Starter, which is a water bath pot with jar lifter and funnel. Water bath boiling cannot sterilize grain spawn, so reserve that kit for jams and pickles only.
Pressure Control, Gauges and Altitude Accuracy
Mushroom grain needs a full 15 PSI hold, usually 90 minutes for quarts, to inactivate endospores. A clear dial gauge matters because a few PSI low can leave survivors that bloom later as contamination. The Presto 01781 23-Quart Pressure Canner and Cooker uses a deluxe pressure dial that registers the complete range, which is especially helpful at altitude, while the Barton 23 Qt Pressure Cooker and Pressure Canner adds a dial plus release valve system for controlled venting during your cycle.
If you dislike watching a burner needle, sensor models reduce guesswork. The Presto 02152 17-Quart Digital Pressure Canner and the larger Presto 02153 23-Quart Digital Pressure Canner use an internal sensor to hold processing temperature with LED prompts and automatic altitude adjustment. The 24qt pressure canner and canning pressure cooker runs at a fixed 14.5 PSI by default and needs a separate three level regulator for 10 PSI work, so confirm your target pressure before you load valuable substrate for oyster mushrooms in a monotub.
Stove Compatibility, Material and Heat Distribution
Heavy gauge aluminum heats quickly and evenly, which helps you reach venting time without scorching. The Presto 01781 23-Quart Pressure Canner and Cooker is warp resistant and works on regular and smooth top ranges, but it is not built for induction. If you cook on magnetic glass, choose the Presto 01784 23-Quart Induction Compatible, which pairs a heavy aluminum body with a stainless steel clad base for gas, electric, smooth top and induction ranges.
Third party alternatives vary widely in base design and alloy. The Wantjoin Aluminum Pressure Cooker 23Qt Pressure uses a thickened composite bottom rated for gas and induction, and the 23+24+ Quart Aluminum Pressure Canner claims universal stovetop use with even heating. Be cautious with the 23.25Quart Stainless Steel Pressure model, which lists 60 kPa operation. That is near 8.7 PSI, well below the steady 15 PSI most growers rely on for grain, even though its stainless body suits Martha tent humidity control fruiting kitchens that also cook in bulk.
Safety Systems and Grower Friendly Operation
You will run your canner for hours each month, so locks, vents and handles matter as much as capacity. Look for an air vent cover lock that prevents opening under pressure, plus a primary regulator and backup relief valve. 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. That routine protects both you and the sterility of your jars.
Presto stovetop models include a sealing ring, rack and guided manual that walk you through venting, pressurizing and cool down. Digital models add hands free holds with audible prompts, which helps if you pour agar while a grain load runs. Pair a reliable cycle with a monotub liner for clean bulk grows and you reduce both contamination vectors and cleanup time from liner leaks and boil overs.
Final Thoughts
For most growers we point to Presto 01781 23-Quart Pressure Canner and Cooker for proven dial control and tall jar fit on standard stoves, while Presto 01784 23-Quart Induction Compatible is the smarter pick if you need induction flexibility without giving up full size capacity.
Frequently Asked Questions
Can you use a Presto 23 quart pressure canner to sterilize mushroom grain spawn?
Yes, that size is ideal for home growers because quart jars stand upright with proper steam flow. Vent steam for ten minutes, bring the dial to 15 PSI, then hold quarts for about 90 minutes. Let the unit cool down on its own so jars do not siphon or crack.
Do you need a full 15 PSI for grain jars and substrate in 2026?
For rye, wheat, millet and sawdust spawn, 15 PSI remains the community standard for dependable results. Lower pressure units can cook food but may leave heat resistant spores viable in dense grain. If you run substrate for oyster mushrooms in a monotub, the same 15 PSI hold gives you a wider margin for large, moist loads.
Will a 23 quart canner work on an induction cooktop?
Only induction rated models will work, since plain aluminum will not couple with a magnetic burner. The Presto 01784 23-Quart Induction Compatible and the Wantjoin composite base model are designed for that use. Confirm your burner diameter and flatness before you buy, as oversized canners can cycle on small portable hobs.
Is a digital canner better than a stovetop dial gauge model for growers?
Digital units like the Presto 02153 23-Quart Digital Pressure Canner simplify timing with sensors and step prompts, which helps beginners. Stovetop dial models give you larger capacity per dollar and simple parts you can service for years. Your choice should reflect your stove, batch size and comfort managing a burner, as discussed in our Midwest versus bulk substrate comparison for scaling up spawn.

These picks are not a good fit if you only ever use pre-sterilized, ready-to-use grow bags; a pressure cooker or canner is aimed at growers making their own grain spawn or bulk substrate from scratch.
