Masontops Pickle Pebble Glass Infinity Weights for Fermenting - Wide Mouth Mason Jar Pickling Weight Set Review (2026)

Who this weight suits

This is aimed at home fermenters who already own wide mouth mason jars, such as Ball, Kerr or Bernardin jars, along with Fido-style jars, and want a single reliable weight rather than a large bulk pack. Masontops built its name on mason jar fermenting accessories, and the Pickle Pebble is its signature weight. Anyone making small batches of sauerkraut, kimchi or pickles in one or two jars at a time gets the most value here, since one pebble is enough to hold shredded vegetables under the brine line. Cooks who run many jars at once, or who ferment large-format batches, may find that a bulk set of weights per jar works out cheaper per unit, even though the Pickle Pebble itself performs the same core job of keeping produce submerged and away from air.

What the glass and shape actually offer

Each Pickle Pebble is a round, wide mouth disc measuring about 2 3/4 inches across and roughly 3/4 inch thick, made from certified, lead-free, food-grade soda lime glass, the same material used in the mason jars themselves. The glass is non-porous, so it will not absorb odors, colors or bacteria from one ferment to the next, and it resists scratching better than plastic weights. The defining feature is the finger-grip cutout at the center, which gives the Infinity shape its name and lets you hook a finger or two straight through to lift the weight out without fishing around with tongs. One pebble is usually enough per jar, though owners can stack a second on top of a shallow ferment for extra downward pressure.

Setting it up and living with it day to day

Using the weight is straightforward: pack shredded or brined vegetables into a wide mouth jar, pour brine over the top, then lower the Pickle Pebble in so it presses the solids below the liquid line before sealing with a lid or airlock. Because the glass is heavy and dense, it stays put once it is submerged, which matters more than it sounds during the first bubbly days of active fermentation. Cleanup is simple, since the glass rinses clean under warm water. Masontops recommends hand washing with soap and water as the primary care method, and says the pebbles can also go on the top rack of a dishwasher as long as an extreme heat or sanitize setting is not used. The brand is explicit that Pickle Pebbles are not meant for boiling or other heat processing, so treat them purely as a fermenting tool, not a canning one.

Trade-offs against other glass weights on the shelf

Compared with an 8-pack of unbranded 2 3/4 inch glass weights built for the same wide mouth jars, the Masontops set gives you a recognized brand and a finger-hole grip in exchange for fewer pieces per purchase, which matters if you run several jars at once and would rather buy weights in bulk. Against a 4-pack of tempered glass weights from Mason Jar Lifestyle, the Pickle Pebble's main edge is that grip cutout, since flat discs without a handle or hole can be slippery to pull out of a deep jar once brine has made everything slick. None of these differences affect how well the ferment turns out, since any dense, food-safe glass weight will hold vegetables under brine equally well; the choice mostly comes down to grip comfort, pack size and how much you want to pay for the Masontops name.

Bottom line and who should look elsewhere

For a fermenter who values a well-known brand, an easy-to-grip shape and glass that matches the quality of a good mason jar, the Pickle Pebble earns its our score of 8.4 out of 10 rating with strong marks for fit and build. It is not the cheapest way to weigh down a jar, and the title alone does not always make the pack count obvious, so double-check the listing for how many pebbles arrive before buying. Anyone fermenting in large batches, running many jars simultaneously, or working with a tight budget will likely get better value from a bulk pack of generic glass weights instead, since the fermenting result is the same either way.
