Canning Pots

Published April 2016
Update, May 2020
Victorio, the manufacturer of our favorite canning pot, has rebranded. Our winner is now called the Roots and Branches Stainless Steel Multi-Use Canner; there have been no material changes to the pot itself and the model number remains the same.

How we tested

A canning pot is an essential tool for large-batch home canning. These pots are typically around 20 quarts—almost twice the size of standard 12-quart stockpots. They should be broad and deep enough to hold a rack (to elevate the jars from the pan floor), a range of jars, and enough water to cover the jars by at least 1 inch. A cheap, black, speckled pot from Granite Ware has been the go-to for decades: Is it still the best option?

To find out, we purchased three nationally available canning pot/rack sets priced from roughly $25.00 to $100.00, including two stainless-steel pots and the classic enameled steel pot from Granite Ware. We tested the pots’ capacity and the racks’ stability by loading and unloading them with different-size canning jars. We timed how long it took for full pots to come to a boil and evaluated the comfort and security of the handles as well as the functionality of the lids. Lastly, we looked at durability: We used the pots and their racks again and again, and we left them damp over several nights to check for rust.

The pots and racks all fit the appropriate mix of jars. All three racks were designed to hang on the pots’ lips for loading and then be lowered down with the jars in place. We found that this feature didn’t work very well (a jar or two always tipped over when we tried it), but the racks worked fine with every mix of jars when we simply left the racks on the bottom of the pots and used jar lifters to move the jars. But rust was a problem with two of the racks, with one leaving angry red marks across the bottom of its pricey stainless pot.

When we timed how long it took the filled pots to come to a boil, the thin pot from Granite Ware did heat the water 5 minutes faster than the thicker, heavier stainless-steel pots (heat moves faster through thin metal). This minimal time savings didn’t prove to be worth much in the grand scheme, especially considering this pot’s major flaw: Its thin enameled porcelain surface was extremely susceptible to chipping (ours did so the first time we used it). Any nick on this pot’s surface exposed the nonstainless steel below, which immediately rusted, creating spots that will eventually turn into holes. The Granite Ware pot may be inexpensive, but it isn’t built to last.

Only one pot/rack combination emerged from our testing rust-free and looking brand-new. It had two features we loved: a clear lid that let us peek inside without disturbing the contents (or getting a faceful of steam) and grippy silicone-coated handles that made moving a giant, hot pot feel a smidge more secure. The Victorio Stainless Steel Multi-Use Canner is more expensive than the classic Granite Ware, but it made canning easier and should last a lifetime.


We tested three canning pots with racks, priced from about $25.00 to $100.00, all purchased online. The pots are listed in order of preference.

Capacity: Pots and racks received high marks for being able to accommodate full batches of canning jars: eight 1-pint jars or four 1-quart jars.

Rack Stability: We rated the racks on how stable they were in use.

Lid: Clear lids that allowed us to see into the pot scored higher than solid lids.

Handles: Handles with heatproof coatings scored higher than plain metal handles.

Durability: We deducted points from pots whose finish chipped or whose racks rusted with normal use.

Value: Pots scored higher if they were less expensive, worked well, and were durable.

The Results


Design Trifecta 360 Knife Block

Admittedly expensive, this handsome block certainly seemed to live up to its billing as “the last knife block you ever have to buy.” The heaviest model in our testing, this block was ultrastable, and its durable bamboo exterior was a breeze to clean. Well-placed medium-strength magnets made it easy to attach all our knives, and a rotating base gave us quick access to them. One tiny quibble: The blade of our 12-inch slicing knife stuck out a little.


Schmidt Brothers Downtown Block

This roomy block completely sheathed our entire winning knife set using just one of its two sides—and quite securely, thanks to long, medium-strength magnet bars. Heavy, with a grippy base, this block was very stable. An acrylic guard made this model extra-safe but also made it a little trickier to insert knives and to clean; the wood block itself showed some minor cosmetic scratching during use.


Schmidt Brothers Midtown Block

This smaller version of the Downtown Block secured all our knives nicely, though the blade of the slicing knife stuck out a bit. With a base lined with grippy material, this block was very stable. An acrylic guard afforded extra protection against contact with blades but made it a little harder to insert knives and to clean; the wood itself got a little scratched during use.

Recommended with Reservations

Swissmar Bamboo Magnetic Knife Block

This small, scratch-resistant model had a stable, rubber-lined base and could hold all our knives, though the blade of the 12-inch slicing knife stuck out a bit. But inch-long gaps between its small magnets made coverage uneven and forced us to find the magnetic hot spots in order to secure the knives. Its acrylic guard made it safer to use but harder to insert knives and to clean.

Not Recommended

Messermeister Walnut Magnet Block

This handsome block was done in by its shape—a tippy, top-heavy quarter-circle that wasn’t tall or broad enough to keep the blades of three knives from poking out. It lacked a nonslip base, and its extra-strong magnets made it unnerving to attach or remove our heavy cleaver. Finally, it got a bit scratched after extensive use.


Epicurean Standing Knife Rack 12"

This magnetic block sheathed all our knives completely, though with a bit of crowding. But it was hard to insert each knife without hitting the block’s decorative slats on way down, and because the block was light and narrow, it wobbled when bumped. Worse, we couldn’t take it apart, so splatters that hit the interior were there to stay. Additionally, the outside stained easily, and when we wiped it down, the unit smelled like wet dog.


Kapoosh Rondelle Knife Block

This model stabilized knives with a mass of stiff, spaghetti-like bristles that shed and nicked easily after extensive use, covering our knives with plastic debris. While all our knives fit securely, several of the blades stuck out, making this unit feel less safe overall. Finally, though the bristles could be removed and cleaned in the dishwasher, their nooks and crannies made this block hard to wash by hand.


Kuhn Rikon Vision Knife Block, Clear

This plastic block required us to aim each knife into the folds of an accordion-pleated insert that was removable for easy cleaning but got nicked easily with repeated use. Because we could only insert the knives vertically, longer knife blades stuck out; a cleaver was too wide to fit. The lightest model in our lineup, this block was dangerously top-heavy when loaded with knives.
