The Best Canning Jars


Best Overall Canning Jar

Weck 742 Mold

Volume: 19.6 fl. oz | Count: 6 | Closure Type: Glass lid with rubber gasket and clips
Widest mouth
Smooth, tapered walls
Thick, durable glass
Reusable seals
Easy to pack and unpack
Stackable and sightly
Easy-to-lose clips
Glass lids can break
Replacement parts harder to find
Pricier than others

The Weck Mold Jars feature a timeless design made with high-quality German glass. Known for their three-piece glass lids with carrot-colored rubber gaskets and metal clips, these jars offer a superior seal with the ability to stack jars for easy storage. Though the price tag is higher than some other products, the investment is worth it for epicurean explorers who prefer a high degree of functionality in their culinary instruments. It may be harder to find replacement parts, but Weck has a wide variety of jars in its lineup that all feature compatible lids, seals, and clips.

These jars come in a pack of six, have a capacity of 19.6 fluid ounces, and feature a straight, tapered wall, so packing is a breeze. In addition, the ultra-wide mouth of the jar makes for easy retrieval of the contents after canning. Cleaning all the various pieces can be tedious, but the fact that they are reusable makes up for it. To safely use these jars in a pressure canner, you'll want to invest in some extra metal clips, as Weck recommends using three clips on each jar under pressure (the set only comes with two for each jar). Overall, the Weck jars are a very high-quality and versatile set for canning with great longevity.

Best Bang for the Buck

Kerr Wide Mouth Quart Jar

Volume: 32 fl. oz | Count: 12 | Closure Type: 2-piece metal lids and bands
Universal wide-mouth lid & opening
Square-sided for easy storage
Familiar, easy-to-use lid
Volume markings on the side
Lids are (technically) not reusable
Bands can get worn out

Kerr Wide Mouth Quart Jars are a classic staple in the kitchen from a well-respected brand. These square-sided quart jars are highly functional and quite affordable, making them a go-to option for folks that do lots of food preservation and need an army of jars on hand at a moment's notice. At their price, the quality of this model is tough to beat.

The wide-mouth design is handy for larger preserves like peach or apple slices. Furthermore, the lids and bands are a universal fit with other wide-mouth jars, so brand compatibility isn't a concern. The 32-ounce vessel has volume markings on the side, so you can monitor fullness as you pack. Thanks to their square sides, a standard 22-quart pressure canner can accommodate seven of these jars at a time, and they fit snugly on a shelf together. If price and utility are your top priorities, we suggest considering the Kerr Wide Mouth Quart Jars.

Best for Jams, Jellies, & Preserves


Volume: 8 fl. oz | Count: 24 | Closure Type: 2-piece metal lids and bands
Easy to use bands and lids
Ideal depth for a butter knife
Quilted glass pattern
Comes with 24 jars
Includes labels to mark jars
Not the highest quality
Smaller by comparison
Lacks longevity

If you're hardcore into jam and preserves, or perhaps looking for a set of jars to make gifts with, check out the Verones 8 oz Jelly Jars. These quilted glass jars fill a classic half-pint niche in canning culture. As a bonus, this pack comes with stickers and a marker for labeling all your tasty preserves. The quality and form of these jars is difficult to differentiate from other name-brand models.

Boasting a total of 24 individual jars, this pack is enough to process a gallon and a half of your favorite food preserves. Though their smaller design lends to jams and jellies, they can also be used for other canned vegetables, sauces, or salsas. The two-piece lids are a universal fit with other regular mouth jars and create a reliable seal. Still, while the jars are well-designed at a reasonable cost, the glass is not quite as thick as others, leaving us to believe that comparative longevity is a concern. Overall, our testers think the Verones is the best option for jelly and jam jars.

Best for Bulk Preservation

Le Parfait Familia Wiss Terrine

Volume: 1 liter | Count: 4 | Closure Type: 2-piece metal lids with full-cap
Very large opening
Smooth and vertical walls
Secure lid with full closure
Durable and high-quality
Not universally sized
More expensive

Without question, our favorite quart option is the Le Parfait Familia Wiss Terrine. With a 110mm opening and a vertical wall all the way up to the rim, these vessels are much easier to pack and empty than any other similar size in the lineup. Hailing from a French brand, the preferred unit of measurement for this model is milliliters. And though the American imperial 32-ounce quart is a quick-math conversion for the metric liter of the Wiss Terrine, these jars are, in fact, larger than a quart and can hold more than standard American jars.

Our testing proved that the larger capacity and totally round shape means that only four of the Wiss Terrines can fit in a pressure canner, as opposed to the standard five quarts. However, the bonus capacity is nearly enough to make up for it. These jars also differ from other models because the two-piece lid comes with a fully “capped” screw top instead of the traditional ring-style lids. The result is a more precise seal and components that don't warp or wear out as easily. The tradeoff is that these are one of the most expensive products of our test group. If you're willing to pay the price per jar for higher quality and better function, definitely consider the Le Parfait Terrines.

An Excellent Pint Jar

Bormioli Rocco Quattro Stagioni

Volume: 17 fl. oz | Count: 12 | Closure Type: 1-piece metal lids
Secure lids with high seal rate
Aesthetically pleasing
Quality glass
Can be used with universal lids
Set of 12
Shoulder taper
Regular mouth

Similar to other European brands, the Bormioli Rocco Quattro Stagioni jars offer a high degree of functionality and design elements that favor more epicurean tastes. The Quattro is one fluid ounce larger than a traditional American pint but more or less subscribes to the same design with squared sidewalls and a regular mouth lid. Having said that, it fits just as well into a traditional pressure canner compared to other pint jars.

Another standout component of this model is the one-piece screw top lid, which has a fully enclosed cap similar to but higher in quality than the North Mountain quarts. Though they are more expensive to replace than standard issue bands (also compatible with the Quattro), these included lids are longer-lasting and provide a more reliable seal. Plus, they're an eye-catching 'gold' instead of gray. If you consider food preservation an art as well as a science, then we'd recommend considering the higher price tag of the Bormioli Rocco Quattro Stagioni pint jars.

Best for Small Items

KAMOTA 10-Ounce

Volume: 10 fl. oz | Count: 24 | Closure Type: 2-piece metal lids and bands
Smooth glass
Universally sized lids
Tremendous value
Reliable seal
Shouldered top
Smaller in size
Less quality than others
Dubious longevity

Registering a total capacity of 10 fluid ounces, the Kamota Jam Jars are actually larger than a standard pint. However, our testers think this model is a good choice for smaller preserves like relishes, chutneys, and tapenades. The pear shape of these jars looks good on a pantry shelf and even features square sides to allow for easier packing in a pressure canner. Though they may not be as fancy as some others, they certainly live up to the task of large-batch food preservation.

Featuring the classic two-piece lids that have a screw top band, these jars provide a quality seal. Furthermore, these lids are interchangeable with any standard regular mouth lid. The shoulder of this jar makes it a little tougher to retrieve jams and jellies, but the overall larger size than a standard pint makes up for it. Plus, the price per jar is tough to beat. If you're looking for an economical and attractive option for canning smaller items, look no further than the Kamota Jam Jars.

A Kitchen Staple

Ball Regular Mouth Quart Jar

Volume: 32 fl. oz | Count: 12 | Closure Type: 2-piece metal lids and bands
Quality glass
Square sided
Reputable brand
Universal lid compatibility
Regular mouth
Pronounced shoulder
Low inventory

The classic Ball Regular Mouth Quart Jar is a staple you'll find in nearly every kitchen. Born from aerospace technology, the Ball brand carries a lot of notoriety and hype. Our testers confirmed that this is indeed a quality jar, provided you can find some online or at your local provisions supplier — they are so popular that it can be challenging to track down the coveted wide-mouth varieties during canning season. For this review, we chose to examine the more readily available regular mouth quarts.

With volume markers and squared-off sides, Ball jars are designed with the experienced canner in mind. Though the taper on the shoulder of these regular-mouthed jars prohibits easy packing and retrieval, their overall functionality is on par with other designer brands. If you're a purist that doesn't need any fancy bells and whistles to accomplish your canning tasks, then you may enjoy the no-frills economy of the Ball Regular Mouth Quart Jar.

A Decent Pint Option

Anchor Hocking 10985

Volume: 16 fl. oz | Count: 12 | Closure Type: 2-piece metal lids and bands
Smooth walls for easy cleaning
Decent value
Universal lid size
Reliable seal
Low-quality glass
Sides aren't square
Lids are tricky sometimes
Shoulders made for difficult packing

Stout and reliable but nothing to write home about, the Anchor Hocking Pint jars are a good off-brand option that offers a simple and utilitarian design. They lack some traditional elements like marks in the glass or square sides, but these jars still have a solid two-piece lid and band closure that can create a reliable seal without any guesswork. They even accept universally sized regular mouth lids.

These jars are a true pint at 16 fluid ounces, though their profile means they stack a bit differently than some pint glasses. For instance, we couldn't fit as many of these jars into a pressure canner compared to square-sided pints due to the rounded glass. However, our testers found this model to be an even-keel performer across the board, not showing distinct strengths or weaknesses. If you're looking for an affordable small jar, definitely check out the Anchor Hocking Pint.

Less Reliable

SPANLA Canning Set

Volume: 4, 8, & 12 fl. oz | Count: 24 | Closure Type: 2-piece metal lids and bands
Set includes three various sizes/shapes
Comes with two different colored lids
Includes stickers for labeling
Quilted glass with vertical sidewalls
Low quality
Thin glass prone to breakage
Lids aren't removable
Must be washed by hand

At first glance, the Spanla Canning Set appears to have everything you need for a successful home canning session. The set comes with various sizes, a cleaning brush, and stickers for making labels. However, our testers found some pronounced drawbacks with these jars compared to other models. Our test pack arrived with five of the 24 jars broken, and an additional two broke during canning, leading us to believe that the manufacturer cut some corners with a lesser quality glass.

Additionally, the included rings pop the lid's seal if you try to unscrew them. This may not be a deal-breaker for some, though many experienced canners prefer to remove the rings after preserving to get them back into circulation. Bottom line: there are better jars to put your jam in. However, if you're looking for a variety of quilted jar sizes in one convenient package, then you may be willing to look past the shortcomings of the Spanla Canning Set.

Our Least Favorite

North Mountain Supply 32-Ounce Quart

Volume: 32 fl. oz | Count: 12 | Closure Type: 1-piece “safety button” metal lids
Large storage capacity
Thicker glass than some
Cylindrical and not squared
Less than awesome seal
1 piece lids
Regular mouth and shouldered top

With few redeeming qualities other than a simplistic design, the North Mountain Supply Quart Jars fall short of the mark in more ways than one. Sometimes, having a simple design bodes well for products that are supposed to offer utility. However, in this case, you'd be better off going for a Ball or Kerr option as they are not only cheaper but have more useful designs.

Perhaps worth noting is that these jars accept a universally sized regular-mouth lid. However, the included one-piece lids aren't very reliable — two of the twelve didn't produce a seal when pressure canned. Though they can hold a full quart of contents, the shoulder taper on these jars is more pronounced than others. If you're looking for quality and utility, we would recommend steering clear of the North Mountain Supply Quart Jars.

Why Trust GearLab

After scouring the market and researching more than 60 different brands, models, and varieties of canning jars, we settled on the ten best for this comprehensive review. Canning jars, by and large, ascribe to certain standards and parameters in order to stay in line with food safety standards. However, there is a degree of variety among styles, designs, and implements that make each jar unique. For this review, we chose to examine a multitude of different styles, including some of the brands that you've come to know well.

As a self-proclaimed 'cottagecore' enthusiast and oddball recipe collector, lead tester, Rob Woodworth, has a proclivity for anything food-related. Furthermore, his propensity to ferment or preserve the abundance from his gardens has left him with strong feelings about how certain jars should work. With an abundance of veggies in his gardens and an insatiable curiosity for DIY food projects, Rob always seems to need more and more jars for his exploits. For this review, Rob used each model as he would in his natural environment—searching for strengths and weaknesses along the way.

Analysis and Test Results

All contenders in this lineup were subject to exhaustive, thorough, and rigorous testing through weeks of repeated use from our testers. A quality canning jar should last for seasons upon seasons of use in the kitchen and should be able to handle various tasks. We heavily weighted our seal testing metric for food safety reasons. Other primary considerations were form, versatility, and longevity. We believe that all of these characteristics combined create a formidable canning jar.


To our testers, form denotes each tested jar's overall shape, size, and style. There was a preference for wide-mouth models because they are easier to pack, vertical sidewalls because they are easier to unpack, and squared sides because they store better on a shelf or in a canner. Size was also a consideration, though less important to the abovementioned criteria. However, our testers were also aware that certain jars are intentionally designed to accomplish certain tasks.

The totally straight but gently angled sidewalls and ultra wide opening of the Weck jars were very easy to use. It also means that you can stack the jars when in storage.

The highest-rated model in this category was the Weck Mold Jar because of their totally straight sidewalls that are wider at the mouth than they are at the base. The result is a remarkably easy jar to pack and retrieve items from—whether with fingers or a fork. Similar to this design was the Le Parfait Terrines, which also have a totally vertical sidewall and large opening without shoulders. However, the deep profile of the Terrines made retrieval harder when compared to the Weck jars.

Other high-performers in the form metric were the Kerr wide-mouth quarts, Ball regular mouth quarts, and the Bormioli Roccos. And though the latter two models have more narrow, “regular-mouth” openings, all three of these jars feature square sides that enable you to fit more jars into a canner or store them more snugly in your pantry.

The underperformers regarding form were primarily the off-brand models that obviously paid less attention to design subtleties that improve overall function. Namely, the Verones, Spanla, and Kamota jam jars were functional but otherwise unimpressive, though due to their primary focus being jams and jellies, we cut them a bit of slack. Whereas the North Mountain Supply and Anchor Hocking jars lacked elements that we would've preferred, like a tapered shoulder or square sidewalls.


The seal is arguably the most important metric for testing canning jars since it ensures the freshness and safety of your preserved food goods. To gain comprehensive insight into each model's ability to produce a seal, we tested each model in the water bath method of canning and using a pressure canner. Often, the intense conditions of a pressure canner can highlight weaknesses in the lid components and sometimes the glass of each jar.

canning jars - there are several different types of lids to create a hermetic seal...
There are several different types of lids to create a hermetic seal on canning jars. Pictured here are the different styles found in this review.
Credit: Rob Woodworth

The jars with the highest scores in the seal category were (not surprisingly) the Ball and Kerr quart models. The lids of both these jars have a marginally wider strip of rubber compared to similar styles. Ball and Kerr have more-or-less set a precedent for the two-piece lid design that incorporates a band to secure the sealed part of the lid. And while we'd like to imagine that other models that mimic their design can hold their own, none of the knock-offs matched the 100% seal rate of Ball and Kerr.

When the rubber tab found on the gasket of the Weck jars is turned down, you know that you have successfully created a hermetic seal. At this point, the clips are no longer necessary.
Credit: Rob Woodworth

Dissimilar in design were the Weck canning jars, which used a glass lid, detached rubber gasket, and two separate metal clips to create a seal. And while this system could produce a good seal, they are more finicky to deal with and more prone to loss or breakage. Also unique were the lids found on the Le Parfait jars, which instead of using a ring, incorporated a fully-capped closure to secure the lid in place during processing. These European models may be a bit odd or unfamiliar in style. But they were also able to provide a 100% seal rate.

The Le Parfait lids were perhaps the most secure, but featured a unique design that utilizes a cap instead of a ring to keep the lids secure during processing.
Credit: Rob Woodworth

The only one-piece lid we were satisfied with was the Bormioli, which had a wide rubber seal and could be used more than once. However, the North Mountain Supply quart jars had a lesser-quality unibody lid that didn't create a seal in two out of twelve jars. The Spanla jelly jars and Anchor Hocking pints also had underwhelming performance compared to some name-brand models.


In some cases, canning jars can be designed for a specific function. For instance, a “mold” jar or “terrine” is designed with straight but slightly slanted walls that allow you to remove the contents in a solid piece by 'plopping' it out when turned upside down. However, most of us aren't in the market for highly specified vessels for epicurean oddities. It stands to reason that when you purchase a canning jar, you'd like it to accomplish various projects.

canning jars - larger jars with wider openings offer more utility to the canner...
Larger jars with wider openings offer more utility to the canner, however, some jars are designed for specific purposes.

Undoubtedly the most versatile canning jar in this review was the Le Parfait, mostly because it boasted the largest volume and widest opening in the lineup, useful for many different food items. The thicker glass on the Le Parfait also made it favorable for freezing. Also receiving notable scores for versatility were the Kerr wide-mouth quart jars, which are a good option for canning anything under the sun.

Smaller jars may not have quite as many uses, but when they are designed well, the user is allowed more creative freedom.

Our testers awarded a higher degree of versatility to the Spanla Canning Set versus the Verones jam jars because the Spanla set had a variety of shapes and sizes. However, the Verones jars were of objectively higher quality. And although the Kamota canning jars are described as jam jars, we found their pear shape to be more conducive to small, diced, or chopped vegetables that can be retrieved with a utensil other than a knife.

Ultimately, regular-mouth jars require a bit more care when packing. Having a canning funnel on-hand is very useful when using jars that have a narrow opening.

At the bottom of the versatility totem pole were the North Mountain Supply jars. Mostly because they have such a pronounced shoulder that certain items are difficult to remove from or pack into the jars, and additionally because they don't handle pressure or freezing very well.


Part of the reason that canning jars are so ubiquitous in the kitchen is that some can last for a super long time. Others won't make it past the first round of batch processing in the pressure canner. While it's difficult to determine which models will stand the test of time, our testers paid close attention to elements like glass thickness and quality of components to differentiate which jars will be in it for the long haul and which models are better for one-and-done batches.

Yet again, the Weck Mold Jars outshone the others in this category. They are constructed with the thickest glass out of the lineup. These jars can withstand lots of wear and tear — even if the lids are breakable, they will last longer before needing to be replaced, unlike traditional lids, which are inadvisable to use more than once.

Our testers were also fond of the durability of the Bormioli and Le Parfait canning jars, which had notably thicker glass than some other models. Furthermore, both of these brands feature more robust metal on their lids when compared to the others fashioned in a similar style. It's also safe to say that the Ball and Kerr jars will give you lots of repeated use, provided that you take good care of them and replace the lids with each new round of processing.

Glass vessels don't always last, though they ought to with proper care. That is why our testers weren't impressed with the Spanla Canning Set, because several jars arrived broken, and some were even damaged in the pressure cooker. While we can understand that shipping is rough on glass, there is no reason that a well-designed canning jar should crack under pressure. Other short-lived jars include the North Mountain Supply and Kamota jam jars, both of which seem to have dubious quality.
