Concord Steam Canner Reviews: Our Honest Verdict

The short version

If you want the verdict before the detail, here's where the Concord lands after reading through a couple hundred owner comments. It's a well-liked, genuinely useful canner with one hard limit you have to understand before you buy.

What's good:

• Uses a fraction of the water a full water bath needs, so it heats up fast and saves energy.
• Light enough to lift, fill, and move without a second person or a full pot of boiling water.
• A validated, safe method for high-acid foods when you stay inside tested times, per NCHFP.
• Hands-off once it hits a steady steam, and friendly to glass-top stoves that hate heavy pots.

What's not:

• High-acid foods only. Meat, beans, and most soups still require a pressure canner, no exceptions.
• Hard 45-minute processing ceiling including altitude, which rules out longer water bath recipes.
• The lid gauge or thermometer knob is the weak point owners fuss over and often double-check.
• Thin, light stainless is easy to lift but tips more readily, and the shallow base holds only so many jars.

Who it's for

The Concord fits a specific canner well and frustrates a different one. Sort yourself before you buy.

Buy it for:

• High-acid preserving: jams, jellies, pickles, salsa, and acidified tomatoes in short processing runs.
• Glass-top stoves, water conservation, or anyone who struggles to lift a heavy full water bath pot.
• Small and mid batches where a quick start beats maximum capacity.

Skip it if:

• You want to can meat, beans, broth, or soups; you need a pressure canner, not any steam canner.
• You regularly run high-acid recipes past 45 minutes; a full water bath like the Granite Ware handles those.
• You put up big batches at once; a taller 20-quart stainless pot fits more jars per load.

The specs that matter

Numbers only help if you know what they buy you. Here's what the Concord's design actually means at the stove:

Shallow base and tall dome lid: you fill the base with only an inch or two of water instead of enough to cover the jars, so it comes to steam quickly and sips energy. That shallow reservoir is also why the clock matters; there is less water in reserve, which is part of why the safe processing ceiling sits at 45 minutes.

Lid temperature gauge or thermometer knob: the tested dome-lid canners tell you when the steam has reached temperature so you know when to start timing. This is the single most important part to get right, and the single part owners complain about most when it drifts or works loose.

Thin stainless construction: the stainless upgrade over the aluminum version is sturdier and easier to clean, and the whole unit stays light. Light is the selling point when you're lifting it, but it also means the canner sits less firmly on the burner than a heavy water bath pot.

How well it preserves

Inside the job it's validated for, the Concord does that job reliably, and owners are consistent about it. The critical thing to understand first is scope. Atmospheric steam canning is a tested, authority-backed method, but only for high-acid foods, and only at the same processing times you'd use in a water bath. One experienced canner lays out the boundary in plain language:

you can not can low acid foods like meat and lentils and most soups in a steam canner. you must have a pressure canner( not a pressure cooker) you can use your steam canner for high acid foods like jams and jellies and pickles. you need to follow safe tested recipes, processes, and sources.

The second half of the rule is the time limit. Steam canning is only validated for processing times of 45 minutes or less, altitude included. Go past that, or move to a low-acid food, and the method is no longer safe. Owners repeat this to newcomers constantly, because it's the one thing that turns a safe canner into a dangerous one:

Also, you can only safely use a steam canner as a substitute for WB processing times of 45 minutes or less including altitude adjustments

Note that if your elevation calls for more than 45 min processing time, it's not safe to use the steam canner and you should water bath instead

Stay inside those lines and the results are dependable. Because the processing times are identical to a water bath, you're not learning a new recipe book, just a new pot. A long-time canner sums up the safety picture cleanly:

It's perfectly safe, and the processing times are the same as with water bath canning. The only difference is that if your processing time is more than 45 minutes you have to water bath process instead.

That's the whole reason the Concord earns its place: for high-acid work it's a true 1:1 swap for a boiling water bath, and plenty of owners now reach for it first. One Concord owner puts it directly, and another lays out the informal rulebook worth taping inside a cabinet:

Atmospheric steam canners are a 1:1 replacement for boiling water bath canners for processing times under 40 minutes. They're totally legit and are recommended as an option by NCHFP. I have one and I love it! I pretty much never break out my boiling water canner anymore. Mine is a Concord brand one but any of the dome style ones are safe to use.

If you're asking why Ball/Bernadin hasn't included steam canning recipes, I'm going to guess it's because the processing times are all the same as water-bath. It does seem like they should include a section about "the rules" (high acid/hot pack only, less than 45 minutes, make sure you can see a 8" steam cloud before starting the time, use the same time, etc.)

The honest performance limit here is not the seal quality; it's the narrowness of what you can safely process and the fact that you're trusting a gauge to tell you when the steam is hot enough. Respect the scope, confirm the temperature, and the Concord preserves high-acid foods as well as the water bath it replaces.

Built to last

This is the softer axis, and it splits into two honest concerns: the light build and the lid gauge. Start with the build. The thin stainless is a feature when you're lifting it, but it's also why a steam canner sits less securely than a heavy pot, something one canner weighing the two methods around kids names outright:

From a safety stand point I'd be alot more comfortable with my kids (who are under 10) around a water bath canner vs a steam bath. I've water bathed canned since I was a kid and steam canning is new to me so that may play a part of it. The steam canner releases steam from the bottom vs the top in a water bath canner, which is a more familiar concept to kids. Also a full water bath canner weighs alot more and is going to be much more difficult to be tipped over where the steam canners are much more lighter due to the less water and so much easier to tip over.

The gauge is where most of the real grumbling lives. On the dome-lid models, a thermometer knob or gauge tells you when to start timing, and owners report it loosening, drifting, or reading oddly often enough that many keep a backup thermometer nearby. Two owners describe the exact failure modes:

Has anyone who has the FruitSaver steam canner (it has the thermometer knob on the top of the lid) had an issue with the thermometer knob falling off/coming unscrewed? It's happened to me twice now. Not sure what I should do to better secure it.

The lid has been off of the pot cooling for Two hours and the gauge has not gone all the way back down. Also, when I did the calibration test, it went way past the max before it stopped. There's something wrong with the gauge?

The practical workaround is the same one experienced canners recommend anyway: don't blindly trust the lid gauge. An instant-read thermometer poked through the vent holes confirms the steam is actually at temperature before you start the clock, which matters more here than on almost any other canner because an under-read gauge means under-processed jars:

I don't really trust the lid gauges they come with so I double check with an instant read air temp thermometer from ThermoWorks. I poke it through the lid holes and verify that the pot is up to temp, it actually takes quite a few minutes at a rapid boil pumping out steam to get up to 211 air temp which is where mine maxes out.

None of this makes the Concord fragile in the pot-fails-in-a-year sense. The stainless body holds up fine; it's the light footprint and the gauge you manage around, not a motor or a seal that dies. But because the gauge is load-bearing for safety and the build is on the flimsy side of the category, durability is the honest weak spot, and it's why the number below sits lower than ease of use.

Living with it

Day to day, the Concord is easy to love, and this is where it clearly wins. The headline is water. Instead of heating a deep pot to cover the jars, you're bringing an inch or two to steam, which is faster, cheaper to run, and far less to haul to and from the sink. Owners who switched from a full water bath describe it almost identically:

I got mine last year and love it. I rarely water bath can anything that needs more than 45 minutes so it’s perfect. It’s fast, uses less water, and uses less energy.

I got a steam canner last year after decades of water bath canning. Never going back!

The weight is the other quiet win, and it's a bigger deal than it sounds. A light canner is one you can lift with jars in it, set on a glass-top stove without worrying about the surface, and manage after surgery or with a bad back. One owner bought hers for exactly that reason and called out the smaller everyday niceties too:

I bought a VKP steam canner(the steel one) when I had to get surgery, it’s great. Wastes less water, prewarms the jars nicely(not full steam, just preheat), easier to lift and move. Figuring out where to put the processing line is the hardest part(I used a thin strip of red tape to mark mine), and the time limit, but there’s so few water bath recipes that run for an extended time it’s not that much of a limitation.

For the stainless-versus-aluminum question that comes up constantly, owners land in the same place: pay the little extra for stainless. It's sturdier, cleans up easier, and doesn't feel like it'll dent in a season:

I have one. Best money I’ve ever spent. I rarely do anything more than 30-45 minutes. Even at 45 minutes it’s nowhere close to drying out. I got the stainless steel one not the aluminum one. I’m glad I got the heavier duty one. It’s been great.

I have a Fruit Saver steam canner and I really like it. I would go for the stainless steel over the aluminum. It has made a huge difference for me in canning because it’s way easier and way quicker.

The learning curve is short and worth naming. You'll spend a batch or two figuring out where the processing line sits and getting comfortable reading the gauge, and a small-batch fit means you're not putting up a truckload at once. A couple of quick endorsements capture how low the friction is once it clicks:

Absolutely. I love my steam canner and it's soo easy and fast. They make a model that's perfect for glass top stoves. I forget the brand but I think it's Harvest or something. Will post link when I'm on laptop if any interest.

Steam canner is awesome. Just be sure to get the one with the shallow bottom and deep top. Great for small batches and lots of other benefits

How it compares

The Concord doesn't exist in a vacuum, and the units people cross-shop against it are mostly full water baths. Here's how it stacks up against each.

Versus the Harvest 20-Quart Stainless Canning Pot: this is the capacity step up. A tall 20-quart stainless pot holds more jars per load and doubles as a deep water bath, so high-acid recipes that run past the steam canner's 45-minute ceiling still have a home. You give back the fast start and the light weight, and you're heating a lot more water.

Versus the Granite Ware Enamel Water Bath Canner: the traditional full water bath, and the honest fallback whenever a recipe processes longer than 45 minutes. It handles every high-acid batch a steam canner can, plus the long ones it can't, and it's cheap and proven. The tradeoffs are the ones the Concord fixes: more water, more weight, a slower start.

Versus the GasOne Canning Pot with Rack: the budget way into water bath canning if you'd rather skip steam entirely. A tall pot and rack cover jams, pickles, and tomatoes at any processing time for a low outlay. You lose the water savings and the light handling, but you also lose the gauge you have to babysit.

Using it well

Get the most out of a Concord with a few habits. Fill the base to the level your manual specifies, no more, and bring it to a full, visible steam column before you even think about timing. Confirm the steam is at temperature with the lid gauge and, ideally, a backup instant-read thermometer through the vent holes, then start your clock; do not start timing the moment you see wisps. Stick to tested high-acid recipes, keep every processing time at 45 minutes or under including your altitude adjustment, and if a recipe runs longer, move it to a water bath instead. Mark your water line so refills are consistent, and never open the lid mid-process.

If you're newer to boiling-water preserving and want the fuller picture before you commit to steam, it's worth reading how the whole method works first. Our guide to the best water bath canner for beginners walks through pot choice, racks, jar handling, and the high-acid rules in more depth, with steam canners in context against the traditional gear.

The bottom line

The Concord Steam Canner is an easy machine to recommend for what it's actually for: high-acid preserving done with less water, a faster start, and a pot you can lift. For jams, pickles, salsa, and acidified tomatoes in short batches, it's a real upgrade in comfort over a heavy water bath, and it's a validated, safe method as long as you stay inside the tested times. Ease of use is its genuine strength, and for a lot of preservers that's exactly the friction that was keeping them from canning more.

What keeps this from a straight rave is scope and build, and both are real. This is a high-acid, 45-minutes-or-less canner, full stop, and treating it like anything more is a food-safety risk, not a shortcut. The thin body and the fussy lid gauge mean you'll manage around a couple of quirks and keep a thermometer handy. Go in understanding the limits, respect the safety line without exception, and the Concord is a lighter, faster, water-saving way to put up the high-acid foods it's built for.
