10 Best Glass Fermentation Weights for Mason Jars
Every successful ferment comes down to one simple rule: keep your vegetables under the brine. Exposed veggies invite mold, kahm yeast and spoiled batches, which is why a good glass fermentation weight is the most underrated tool in any fermenting kit. Unlike DIY solutions such as cabbage leaves or zip bags, glass weights are non-porous, easy to sterilize and heavy enough to hold everything down.
In this guide, we review ten of the best glass fermentation weights for wide mouth mason jars, comparing grip design, weight, fit and value. Whether you ferment small batches of pickles or run a steady rotation of sauerkraut and kimchi, you will find a set here that matches your jar collection and batch size.

SOLIGT 4-Pack Glass Fermentation Weights – Stable Bulge Handle Design
Brand: SOLIGT
A dependable four-pack whose stable handle makes jar removal effortless batch after batch.
The SOLIGT 4-pack stands out for its smart bulge handle, which gives you a much more stable grip than grooved alternatives. Instead of fishing a slippery disc out of the brine with your fingers, you simply pinch the raised handle and lift. The food-safe glass is lead free and non-porous, so it never absorbs odors, flavors or colors from your ferments.
These weights fit typical wide mouth mason jars perfectly, making them ideal for small batches of fermented vegetables. Each disc is large and heavy enough to keep vegetables fully submerged below the brine, which is exactly where they need to stay for clean lacto-fermentation. Compared to DIY weights, they deliver more consistent results with far less fuss, and the four-pack covers a solid rotation of jars.
- Bulge handle lifts out easily
- Lead-free non-porous glass
- Heavy enough to submerge veggies
- Wide mouth jars only
- Four jars may not suffice
Eleganttime 4-Pack Fermentation Weights – Smooth Flat-Bottom Glass
Brand: eleganttime
Smooth, heavy and seam-free, these weights keep ferments flat and fully submerged with ease.
Eleganttime ships four weights, each tipping the scales at 7 ounces, with a flat bottom that sits evenly over your vegetables. That flat surface matters more than it sounds: it avoids the air pockets that form under rounded or seamed weights, keeping oxygen away from your ferment. The clear, smooth glass has no seams to trap food particles or bacteria.
The ribbed handle is the highlight here, making removal from wide mouth mason jars noticeably easier than grooved designs. With a 2.7 inch diameter, each weight is specifically sized to fit all wide mouth jars, so you can pair them with quart jars of sauerkraut or pint jars of pickles. At 7 ounces each, they are heavy enough to hold shredded cabbage down firmly under the brine throughout the entire fermentation period.
- Heavy 7-ounce flat bottom
- Seamless easy-clean glass
- Ribbed grip simplifies removal
- Only fits wide mouth jars
- No protective packaging noted
MFacoy 4-Pack Fermentation Weights – Gift-Ready Protected Kit
Brand: Mfacoy
A well-protected four-pack that arrives intact and keeps every ferment safely under brine.
MFacoy focuses on doing the fundamentals well. Each weight is 2.76 inches in diameter, 0.8 inches tall and 7 ounces, sized to stabilize fermentation inside wide mouth jars without slipping sideways. The lead-free, non-porous glass is ultra-clear, so you can watch your brine cloud and bubbles rise without lifting the lid, and it will not absorb odors, flavors or chemicals over time.
Where this set genuinely differs is packaging. Each set of four arrives in a sturdy color box with thick pearl cotton foam, which dramatically cuts the risk of breakage in transit. That also makes it a genuinely gift-ready option for the fermenting enthusiast in your life. The weights are dishwasher safe and easy to clean between batches, and they keep pickles, sauerkraut and kimchi reliably submerged for healthy fermentation every time.
- Foam-protected gift-ready box
- Dishwasher-safe clear glass
- Secure no-slip jar fit
- Only four weights included
- Sized for wide mouth jars
Country Trading Co. Fermentation Weights – Wide Easy-Lift Handles
Brand: Country Trading Co.
Thoughtfully designed weights with wide handles that make lifting out of brine completely painless.
Country Trading Co. designed these weights around the two tasks you repeat most often: sterilizing and lifting. The smooth glass surface wipes clean and sterilizes easily before use on lactic ferments like sauerkraut, kimchi and vegetable pickles, with no grooves or seams for bacteria to hide in. Hygiene before fermenting is half the battle, and this set makes that step simple.
The wide handles are the real differentiator. You can insert and extract the weights from wide mouth mason jars with ease, with no more fishing discs out of the brine using your fingers. Each weight is genuinely heavy, unlike lighter discs that float or tilt once fermentation gets active and bubbles push upward. As part of a broader fermenting kit, they do the essential job of holding everything below the protective brine where spoilage cannot start.
- Wide handles for easy lifting
- Smooth surface sterilizes quickly
- Heavy enough for active ferments
- Wide mouth jars only
- No multipack value sizing
LELELUK 2-Pack Fermentation Weights – Extra-Heavy Small-Batch Pair
Brand: LELELUK
A heavier two-pack built for small-batch fermenters who want quality without buying extra weights.
Not everyone needs four or nine weights, and LELELUK is the rare brand that acknowledges that. This 2-pack is perfectly portioned for small-batch fermentation, so you avoid paying for bulky sets you will never fill. It is also a smart choice if storage space is tight and you only run one or two jars at a time.
Each weight is approximately 7.1 ounces, or 202 grams, which is slightly heavier than many competing discs and gives excellent submersion power for consistent fermentation. The 7 centimeter, 2.75 inch diameter offers full surface coverage across standard wide mouth mason jars in 16, 24, 32 and 64 ounce sizes, so shredded vegetables cannot sneak up the sides. The finger-friendly grip lets you lift the weight out without disturbing your ferment, keeping mess and floating debris to a minimum.
- Heavier 7.1-ounce design
- Fits four jar sizes
- Right-sized two-pack value
- Only two weights included
- Too few for large batches
Cedilis 9-Pack Fermentation Weights – Best Value Bulk Set
Brand: Cedilis
Nine sturdy weights at a value price, ideal for anyone fermenting several jars at once.
If you ferment in volume, the Cedilis 9-pack is the value play. Nine glass weights, each roughly 2.75 inches in diameter and 0.8 inches thick, let you run a full shelf of wide mouth mason jars simultaneously without juggling weights between batches. For anyone making sauerkraut, kimchi and pickles in rotation, that capacity is genuinely useful.
The dotted knob handle is a clever touch, providing enhanced friction for a secure grip when inserting and removing weights from brine-filled jars. Each weight is a substantial 7 ounces, and the flat-bottom design presses vegetables down evenly to keep them submerged. The solid soda-lime glass is non-porous and built to withstand repeated use and dishwasher cycles, so the set should last through years of fermenting seasons rather than a single summer of pickles.
- Nine weights for bulk fermenting
- Dotted knob adds grip friction
- Durable dishwasher-safe soda-lime glass
- Overkill for occasional fermenters
- Requires wide mouth jars
Masontops Pickle Pebble Weights – Trusted Regular Mouth Option
Brand: Masontops
The go-to Pickle Pebble for regular mouth jars, from a brand built around mason jars.
Masontops is the mason jar accessories specialist, and Pickle Pebbles are its signature fermenting weight. The brand’s core promise is simple: keeping vegetables submerged in brine is the critical step in making healthy, delicious fermented food, and these weights prevent the spoilage that ruins unprotected batches. The non-porous, crystal clear glass lets you watch your ferment’s progress at a glance.
Notably, this is the set to choose if your jar collection leans regular mouth rather than wide mouth, since Pickle Pebbles come in both sizes and this version is the small mouth fit. The finger grip design lets you pinch and pull the pebble out quickly once you are ready to sample your fermented vegetables. If you already own other Masontops fermenting gear, these weights slot neatly into a complete, matching mason jar fermentation kit.
- Fits regular mouth jars
- Pinch grip for quick removal
- Crystal clear non-porous glass
- Not for wide mouth jars
- Smaller coverage per weight
YOUEON 9-Pack Fermentation Weights – Diamond Handle Bulk Kit
Brand: Youeon
A generous nine-pack with a distinctive diamond handle that handles even pungent ferments well.
The YOUEON 9-pack combines bulk value with a distinctive diamond-shaped bulge handle. Each weight measures 2.75 by 1.4 inches and weighs about 7 ounces, with a round shape that fits most standard wide mouth mason jars and pickling jars. The taller 1.4 inch profile gives the handle extra clearance above the brine, so extraction stays clean.
The glass is thick, heavy, lead free and non-porous, meaning it will never absorb food odors, flavors or colors no matter how pungent your kimchi gets. In practice, these weights do exactly what they should: they hold vegetables firmly under the brine and weigh them down consistently through the most active phase of fermentation. Beyond sauerkraut, pickles and kimchi, the set works for virtually any vegetable ferment you run in mason jars, making it a versatile fermenting kit staple.
- Nine heavy 7-ounce weights
- Diamond handle lifts cleanly
- Odor-proof non-porous glass
- Taller profile raises lid height
- Wide mouth jars required
Nexboraque 9-Pack Fermentation Weights – Food-Safe Bulk Essentials
Brand: Nexboraque
Simple, food-safe and sold in bulk, this nine-pack keeps every jar's contents submerged.
Nexboraque delivers another strong nine-weight value pack, with each glass weight coming in at 7 ounces and 2.75 inches in diameter for a snug, proper fit in wide mouth mason jars. The food-safe glass is made without lead and is fully non-porous, so it will not absorb food odors, flavors or colors even after years of briny service.
The diamond-shaped handle is the practical standout, giving you a stable, confident grip when removing weights from jars mid-ferment. That stability matters during active fermentation, when brine is cloudy and slippery discs are hardest to grab. Functionally, these weights are essential for successful fermentation: they keep vegetables submerged below the brine, which is what prevents the spoilage that ruins otherwise good batches. If you want a bulk supply of straightforward, dependable weights, this set covers it.
- Nine food-safe lead-free weights
- Diamond handle grips securely
- Prevents spoilage reliably
- No smaller pack option
- Wide mouth jars only
Xileanalee 4-Pack Fermentation Weights – Deep-Jar Pickling Pair
Brand: Xileanalee
Solid soda lime weights whose reachable grip makes deep pickling jars far easier to manage.
Xileanalee’s four-pack covers the essentials with well-chosen materials and sizing. The weights are made from the same food-safe soda lime glass as mason jars themselves, non-porous and lead free, so there is no worry about flavors or chemicals leaching into your brine. Each disc is 2.75 inches in diameter, 0.8 inches tall and 7 ounces, sized for medium and wide mouth jars.
Heavy enough to keep every piece of vegetable submerged in the brine, they deliver the crisp, delicious pickles and sauerkraut you are aiming for without spoiled batches. The easy grip handle solves the classic frustration of slippery, deep-sunk weights: when a weight sits too far down in the jar, you can still pinch and lift it out quickly instead of digging for it with fingers or utensils. For pickling projects in taller jars, that reachability is a real advantage.
- Soda lime glass matches jars
- Grip works in deep jars
- Heavy 7-ounce submersion
- Four weights limit batch size
- Medium jars need size check
Buyer’s Guide: What to Consider
All fermentation weights look similar at first glance, but small differences in weight, handle design and jar fit affect daily use. Here are the five factors worth checking before you buy.
- Weight and Heft: Most quality glass weights weigh around 7 ounces, which is heavy enough to hold shredded cabbage and chopped vegetables down even during active, bubbly fermentation. Lighter discs can tilt or float once bubbles push upward, exposing vegetables to air. If you ferment watery vegetables or large shredded batches, lean toward the heavier end, such as the 7.1-ounce LELELUK weights.
- Handle Design: The handle determines how easily you can retrieve a slippery, brine-coated weight from a deep jar. Bulge and diamond-shaped handles give a stable pinch grip, ribbed and dotted knobs add friction, and wide handles suit larger fingers. Avoid purely grooved designs, which are harder to grip once coated in cloudy brine.
- Jar Compatibility: Most weights here are 2.7 to 2.76 inches in diameter, sized for wide mouth mason jars. If your collection includes regular mouth jars, you need a dedicated small mouth option like the Masontops Pickle Pebble. Always check jar size before buying, since a weight that is too small lets vegetables float up the sides.
- Glass Quality and Safety: Choose lead-free, food-safe, non-porous glass. Non-porous surfaces will not absorb odors, flavors or colors from pungent ferments like kimchi, and they sterilize easily between batches. Smooth, seam-free glass is also simpler to clean and leaves fewer places for bacteria to hide before you start a new ferment.
- Pack Size and Value: Match the pack size to your habit. Two-packs like the LELELUK suit occasional small batches, four-packs such as SOLIGT or MFacoy cover a steady rotation, and nine-packs from Cedilis, YOUEON or Nexboraque suit anyone fermenting a full shelf at once. Bulk sets cost more upfront but lower the per-weight price.
Conclusion
Glass fermentation weights are a small investment that protects every jar you ferment. The fundamentals are consistent across all ten options: lead-free, non-porous glass, roughly 7 ounces of heft and a diameter matched to wide mouth mason jars. What separates them is handle design, pack size and small touches like protective packaging or flat bottoms that prevent air pockets.
For most fermenters, the SOLIGT 4-pack is the balanced pick, while bulk fermenters should choose the Cedilis or YOUEON 9-packs and regular mouth jar owners need the Masontops Pickle Pebble. Pick the set that matches your jar collection and batch size, keep everything under the brine, and your sauerkraut, kimchi and pickles will thank you.
