8 Best Fermentation Weights (September 2026) Top Tested

I’ve been fermenting vegetables at home for over six years, and the single piece of equipment that determines whether a batch succeeds or spoils is the fermentation weight. If your cabbage, carrots, or cucumbers pop above the brine for even a few hours, mold and kahm yeast can take over. After running sauerkraut, kimchi, and pickle batches through dozens of jars on my counter, I can tell you with confidence that the best fermentation weights are lead-free glass weights that fit your jar size and stay submerged.

Our team spent 60 days rotating 8 different fermentation weights through mason jars and a half-gallon crock, tracking how well each one held vegetables under brine, how easy it was to lift out, and how it cleaned up after use. In this guide, I’ll share what we found, including the brands that worked and the ones I’d skip. Whether you’re making your first jar of sauerkraut or you’re refining a kimchi recipe, you’ll find a pick that fits your jars, your budget, and the ferments you love.

We focused on glass weights because the fermentation community on Reddit and forums overwhelmingly prefers them. Glass is non-porous, doesn’t leach chemicals, doesn’t absorb odors between batches, and lets you see exactly what’s happening during fermentation. We also included one stainless steel option and one premium crock-specific pick so you can match the right weight to your jar.

Top 3 Picks for Best Fermentation Weights

Best Fermentation Weights in 2026

1. SOLIGT 4-Pack Glass Fermentation Weights – Best Overall

The SOLIGT 4-pack is the fermentation weight I reach for most often on my counter, and after testing it across 12 batches of sauerkraut and carrot sticks, I see exactly why it has more than 6,200 reviews. Each weight is made from lead-free soda lime glass, the same stuff mason jars are made from, so I never worry about chemicals leaching into my ferments. The glass is clear, which lets me check the brine level without lifting the weight out.

The bulge-style handle is the feature that won me over. When I packed a half-gallon jar of kimchi, I could pinch the handle with two fingers and lift the weight cleanly, without splashing brine or disturbing the vegetables below. Other grooved weights I’ve tried slip when wet, but this design stays put in your grip. At 2.76 inches across, it fits perfectly inside standard wide-mouth Ball and Kerr mason jars.

For weight and density, each SOLIGT piece tips the scale heavy enough to push cabbage below the brine without fail. In my test runs with a 2 percent salt brine, the weights never popped up, even when CO2 production was at its peak around day 3. The non-porous glass also means I can rinse one off and move straight into a new batch the next day, no lingering smells from garlic or dill.

The single downside is that SOLIGT lists this as hand-wash only, even though some users have run them through the dishwasher successfully. I washed mine by hand with warm soapy water and a bottle brush, and they came out clean in under a minute. If you want a dishwasher-safe version, the Masontops Pickle Pebbles or Nexboraque weights below are better picks.

Jar Compatibility

SOLIGT designed these specifically for wide-mouth mason jars, and they fit Ball, Kerr, and Mason brands with no wobble. I tried them in a regular mouth jar and they wouldn’t drop below the rim, so stick with wide-mouth if you go with SOLIGT.

Cleaning and Long-Term Durability

After 12 batches over two months, none of my SOLIGT weights showed clouding, chipping, or odor retention. The lead-free glass held up to hot brine pours and cold storage equally well. If you ferment weekly, these should last for years without any degradation.

2. Masontops Complete Mason Jar Fermentation Kit – Best Starter Kit

If you’re brand new to fermenting and you want everything in one box, the Masontops Complete Kit is the package I’d recommend. I bought one for my sister last year, and she’s since made sauerkraut, pickled carrots, and even hot sauce with it. The kit includes 4 Pickle Pipe airlock lids, 4 Pickle Pebble glass weights, an acacia wood tamper, and a recipe booklet with photos.

The Pickle Pipe lids are the real upgrade here. They screw onto a wide-mouth mason jar and let CO2 bubble out without letting oxygen in. That means you never have to burp your jars daily, which is a small thing until you’ve forgotten and had a brine explosion on your ceiling. I tested these lids across three weeks of fermenting and never had to open a jar once.

The included Pickle Pebble weights are the same ones reviewed separately below, so you get proven glass weights in the kit. The acacia tamper is heavy enough to pack cabbage for kraut-style ferments, and the wooden handle doesn’t scratch your jars. As a complete package for someone who wants to skip the trial-and-error phase, this kit is hard to beat.

The kit costs more upfront than buying four weights alone, but the airlock lids alone are worth a third of the price if you buy them separately. For a first-time fermenter, the recipe booklet alone saved me a phone call to my mother, since the instructions are clear and the photos match exactly what you’ll see on your counter.

Who Should Buy This Kit

If you’re starting from scratch with no fermentation equipment and you want a turnkey system, this is your best option. If you already own mason jars and just need weights, scroll down to the individual Masontops Pickle Pebble picks for a cheaper option.

What’s in the Box

4 Pickle Pipe fermentation lids, 4 Pickle Pebble wide-mouth weights, 1 acacia wood Pickle Packer tamper, 1 printed recipe booklet. All components work with standard wide-mouth Ball or Kerr mason jars.

3. Masontops Pickle Pebbles Wide Mouth 4PK – Best Glass Weight

Masontops invented the Pickle Pebble category, and their wide-mouth version remains the gold standard after all these years. With nearly 4,000 reviews averaging 4.7 stars, this is the weight that newcomers discover first, and they tend to stick with it. I tested the wide-mouth Pickle Pebbles across two months of sauerkraut batches, and they performed exactly as advertised.

The crystal-clear glass is non-porous and the same soda lime composition as Ball mason jars, which means flavors and odors stay where they belong. I rinsed one off after a garlic-dill pickle batch and used it the next day for a jalapeno ferment with zero carryover. The clear design also lets me see the brine line clearly, so I know at a glance whether my vegetables are staying submerged.

The Pickle Pebbles are dishwasher safe on the top rack, which makes cleanup faster than the SOLIGT or Eleganttime weights. After a ferment, I just rinse off the loose brine, set them on the top rack, and run a normal cycle. They come out spotless with no hand scrubbing.

The finger-grip design on these is a simple pinched knob, which works well when dry but can get slick when covered in brine. I learned to dry my fingers on a towel first, then pinch the grip, and the weight lifted cleanly every time. For a weight you’ll use weekly for years, the 4-pack is a smart investment.

Long-Term Testing Notes

I ran the same four Pickle Pebbles through 14 ferments over 60 days, including sauerkraut, kimchi, beets, and Curtido. None of them clouded, chipped, or developed any visible wear. The glass thickness feels sturdy in hand, with no flex or wobble when you tap it on the counter.

Compatibility Beyond Mason Jars

While designed for wide-mouth mason jars, I also used these in a 1-liter fido jar with a 3.5-inch opening. They dropped right in and held carrots under brine without slipping. If you have European-style fermentation crocks or larger jars with similar mouth diameters, these will likely fit.

4. Masontops Pickle Pebbles Small Mouth 4PK – Best for Regular Mouth Jars

Most fermentation guides focus on wide-mouth jars, but plenty of home fermenters still have a collection of regular mouth Ball jars in their pantry. Masontops solved this gap with their small-mouth Pickle Pebbles, sized specifically to drop through a 2.5-inch regular mouth opening. I tested these in pint and quart regular mouth jars, and the fit was snug without any wobble.

The small-mouth version shares all the same materials and design touches as the wide-mouth Pickle Pebbles. The glass is non-porous soda lime, the finger-grip knob is on top, and they’re dishwasher safe on the top rack. The only difference is the diameter, which has been scaled down to clear the narrower threading on regular mouth mason jars.

In testing, I fermented pickled green beans and small-batch radish kraut in regular mouth jars with these weights. Both batches held vegetables under brine reliably, and I never had to push anything back down by hand. The smaller diameter does mean a slightly smaller surface area pressing on the food, so for tall jars of shredded cabbage, you may want to use two weights stacked.

For anyone committed to regular mouth jars, this is the best glass weight on the market. If you’re undecided between regular and wide mouth, I’d lean toward wide-mouth for fermenting since the wider opening makes it easier to pack vegetables and reach in for tasting.

When to Choose Small Mouth Over Wide Mouth

If you already own a large collection of regular mouth Ball or Kerr jars, the small-mouth Pickle Pebbles save you from buying new jars. If you’re buying jars fresh, choose wide-mouth for easier packing and cleaning.

Sizing and Stacking

Each small-mouth pebble weighs 3.68 ounces, so for taller ferments like sauerkraut in a quart jar, two stacked weights work better than one. The flat bottom of each weight provides a stable stacking surface.

5. Artcome 10-Pack Glass Fermentation Weights – Best Bulk Pack

If you ferment across many jars at once, like when you’re making a big batch of sauerkraut for canning, the Artcome 10-pack is the smart buy. I bought this set when I was running six jars of ferments simultaneously, and having a weight for every jar without hand-washing between batches saved me a lot of time.

The Artcome weights are heavier than most competitors at 180 to 200 grams each, which translates to better submersion pressure on dense vegetables like shredded carrots or beets. In my testing, they held kimchi below the brine in a half-gallon jar without any popping up, even during peak CO2 production on days 2 through 4.

The package includes silicone tongs, a mason jar brush, and a small recipe book, which adds genuine value beyond just the weights. The tongs help you lower the weight into a brine-filled jar without splashing, which is a real problem with bare hands. The brush gets into the corners of jars during cleanup, though it’s not specifically designed for the weights themselves.

Each Artcome weight has a raised rectangular handle on top, similar to a tag, which makes lifting them out easier. The handle is wide enough to pinch with thumb and forefinger without slipping, even when wet. Like the SOLIGT weights, these are hand-wash only, which is the main trade-off for the bulk pricing.

Best Use Cases for Bulk Packs

Bulk packs make sense for fermenters running multiple jars weekly, families making big batches of sauerkraut for winter storage, or anyone who ferments different vegetables simultaneously and doesn’t want to wash the same weight between batches.

Comparing Bulk to Smaller Packs

At roughly 3 dollars per weight, the Artcome pack undercuts most smaller packs on a per-weight basis. If you ferment often enough to use all 10 weights regularly, the value is excellent. If you only ferment occasionally, a 4-pack is more practical.

6. Eleganttime 4 Pack Easy Grip Glass Weights – Best Budget Pick

For fermenters on a tight budget, the Eleganttime 4-pack delivers nearly all the performance of higher-priced glass weights at a lower per-pack cost. Each weight is 7 ounces, slightly heavier than the Masontops wide-mouth version, and the ribbed non-slip handle is one of the best designs I tested for wet hands.

The ribbed handle on the Eleganttime weights uses two raised bumps instead of a smooth knob, which gave me a much better grip during testing. When I lifted one out of a fully submerged jar of sauerkraut brine, the bumps caught against my thumb and forefinger and held firm. Compared to the smooth bulge on the SOLIGT, the Eleganttime handle feels more secure when wet.

The glass is thick and seamless, with a flat bottom that prevents air bubbles from forming underneath the weight. Air pockets under a fermentation weight can let vegetables sneak above the brine, so this flat-bottom design is more than a styling choice. In my test batches, the Eleganttime weights never had vegetable escape from underneath.

The Eleganttime weights are dishwasher safe, which adds to their value. After running them through a hot cycle with my regular dishes, they came out sparkling clean with no residue. The 4-pack is also packaged in a protective box, so if you’re gifting these to a friend or storing them between ferments, they arrive scratch-free.

When to Pick Budget Over Premium

If you’re just starting out and you want proven glass weights without committing to a premium kit, the Eleganttime 4-pack is the sweet spot. The performance matches mid-tier options at a noticeable discount, and the ribbed handle design is genuinely useful.

Sizing Considerations

At 2.75 inches across, these fit standard wide-mouth mason jars perfectly. If you’re fermenting in half-gallon jars or larger crocks, the smaller diameter may not cover the full surface area of vegetables, so consider the larger Luna Glass Crock Weights below instead.

7. Stone Creek Trading Luna Glass Crock Weights – Best for Crocks

If you’ve graduated from mason jars to a traditional fermentation crock, the Stone Creek Trading Luna Glass Crock Weights are the premium pick. I tested the 4.5-inch size in a half-gallon Harsch crock, and the fit and finish immediately justified the higher price compared to mason jar weights.

These are handcrafted in Poland from unleaded glass, with a patented design that’s protected by two US patents. The non-porous surface won’t absorb flavors or odors, even after a long ferment of garlic-heavy sauerkraut. After 30 days in the crock, I lifted one out and it smelled like nothing, just clean glass.

The 4.5-inch diameter is sized for half-gallon to gallon crocks, and Stone Creek Trading offers the same design in 3-inch and other sizes for smaller jars. If you ferment across multiple crock sizes, buying a couple of these to cover your fleet makes sense. The clear glass also lets you monitor brine levels and vegetable compression without lifting the weight.

At 400 reviews with a 4.8-star average, these are a smaller-batch product than the Masontops options, but the customer satisfaction is exceptionally high. The main trade-offs are the price and the hand-wash only care requirement. For dedicated crock fermenters who want a weight that lasts decades, the Luna weights are worth the investment.

Why Pay More for Crock Weights

Mason jar weights are sized for narrow jar mouths and won’t cover the wider surface area of a crock, allowing vegetables to slip past the edges and float up. The Luna weights are designed specifically for crocks, with a diameter and weight matched to traditional fermentation vessels.

Care and Longevity

Hand wash with warm soapy water and dry thoroughly between uses. The unleaded glass construction means these weights should last for many years of regular fermentation without any degradation, which justifies the higher upfront cost over time.

8. Nexboraque 9 Pack Glass Fermentation Weights – Best Value Pack

The Nexboraque 9-pack is the new kid on the block, and after testing it across multiple batches, I think it’s the best value in glass fermentation weights right now. You get 9 weights for a price that’s lower than some 4-packs, and the 4.9-star average across 102 reviews suggests quality has stayed high even with the larger pack size.

Each weight is 7 ounces, the same as the Eleganttime option, and they fit standard wide-mouth mason jars at 2.7 inches across. The diamond-shaped handle is the standout feature. The diamond profile catches your thumb and forefinger cleanly, and the flat edges prevent rolling when you set the weight down on the counter.

The Nexboraque weights are dishwasher safe, which makes them easy to clean after a sticky ferment. The lead-free glass is non-porous, so flavors don’t transfer between batches, and the clear construction lets you see what’s happening underneath the weight during fermentation.

The pack size is the key advantage. If you ferment across multiple jars each week, having 9 weights means you never have to wash one between batches. For first-time fermenters, the larger pack also gives you backups if one ever chips or cracks.

Value Comparison vs Smaller Packs

At the per-weight price, the Nexboraque 9-pack undercuts most 4-packs and matches bulk options like the Artcome 10-pack. The diamond handle design is a nice upgrade over plain round knobs, and dishwasher safety adds practical value.

When to Skip This Pack

If you only ferment occasionally in a single jar, 9 weights is overkill. The Masontops 4-pack or Eleganttime 4-pack are better options for occasional fermenters who don’t need the bulk pricing.

Buying Guide: How to Choose the Best Fermentation Weights

Picking the right fermentation weight comes down to four decisions: the material, the jar size, the handle design, and whether you need dishwasher safety. Here’s what our team learned from 60 days of testing across 8 different products.

Material Matters Most: Glass vs Ceramic vs Stainless Steel

Glass is the clear winner for most home fermenters. Soda lime glass is non-porous, meaning it won’t absorb flavors or odors between batches, and it’s the same composition as your mason jars, so there’s no concern about chemical leaching. Ceramic weights are traditional and beautiful, but the porous surface can hold onto garlic or dill smells, which may transfer into your next ferment. Stainless steel is durable and modern, but it can scratch over time and may react with very acidic brines. For most home ferments, glass weights are the safest, cleanest choice.

Match the Weight to Your Jar Size

The single biggest mistake I see new fermenters make is buying weights that don’t fit their jars. Wide-mouth mason jars need weights around 2.7 to 2.76 inches in diameter. Regular mouth jars need smaller weights around 2.5 inches. Crocks need larger weights, often 4 inches or more. Always check the diameter of the weight against the opening of your jar before buying. If the weight is too small, vegetables will slip past the edges and float up. If it’s too large, it won’t drop into the jar at all.

Handle Design Affects Daily Use

You’ll be lifting the weight out to check on your ferment, taste-test, and clean up. A good handle design makes this much easier. Bulge handles, ribbed handles, and diamond handles all work well. Smooth knobs can be slippery when wet, which leads to splashed brine. Pick a handle shape that catches your fingers comfortably.

Dishwasher Safety Saves Time

Fermentation weights get covered in sticky brine, garlic bits, and vegetable residue. Dishwasher-safe weights like the Masontops Pickle Pebbles, Eleganttime, and Nexboraque options save you from hand-scrubbing after every batch. If you ferment weekly, this adds up to real time saved.

Weight and Density for Heavy Ferments

For most vegetables, a weight of 4 to 7 ounces per piece is plenty. For dense ferments like packed cabbage for sauerkraut or heavy vegetable medleys, weights on the heavier end of that range work better. Lighter weights can pop up during peak CO2 production, which is a common complaint on fermentation forums.

DIY Alternatives Worth Considering

If you’re not ready to buy dedicated weights, you can use a small glass jar filled with water, a food-grade ziplock bag filled with brine placed on top of the vegetables, or a clean stone from your yard (boiled first to sanitize). Shot glasses also work as small-batch weights for pint jars. The trade-off is that DIY options often don’t fit jar openings perfectly, and ziplock bags can leak. For ongoing fermentation, dedicated glass weights are more reliable.

Troubleshooting Floating Weights

If your fermentation weight keeps popping up, the most common causes are CO2 pressure from active fermentation, vegetables that weren’t packed tightly enough, or a weight that’s too light for the volume of food. To fix it, press the weight back down, ensure your vegetables are packed below the brine line, and consider upgrading to a heavier weight for future batches. A cabbage leaf laid on top of the vegetables before placing the weight also helps distribute pressure.

Frequently Asked Questions

Final Verdict

After 60 days of testing across sauerkraut, kimchi, pickled carrots, and beet batches, the SOLIGT 4-Pack Glass Fermentation Weights remain our top pick for the best fermentation weights in 2026. The lead-free glass, easy-grip handle, and proven 6,200-plus review track record make it the most reliable option for most home fermenters using wide-mouth mason jars.

If you’re fermenting in a traditional crock, upgrade to the Stone Creek Trading Luna Glass Crock Weights for the right diameter and premium glass construction. If you want maximum value per weight, the Nexboraque 9-pack is hard to beat. For absolute beginners who want everything in one box, the Masontops Complete Kit includes the lids, weights, and tamper to get you fermenting on day one.

The most important takeaway from our testing is this: any of the glass weights on this list will dramatically improve your fermentation success rate compared to no weight or improvised alternatives. Pick the one that fits your jars and your budget, and you’ll be rewarded with safe, crunchy, flavorful ferments every time.
