Sauer Stones by Fermentology are designed specifically to fit in the opening of regular mouth Mason jars. Ferment kraut, pickles, kimchi and more in Mason and canning jars, or even crocks. Making homemade lacto fermented foods is easy with Sauer Stones: they weight vegetables below the brine, like cabbage, cucumbers, carrots, and more, to prevent spoilage. Just place them in the jar with the prepped ferment, lightly press down, and start fermenting. Your gut will be so nourished after eating your own fermented foods because they’re full of probiotics. Sauer Stones can be used with other great Fermentology fermenting products, including our airlock lids and Sauer Stick tamper, or other brands like Masontops, including their silicone fermenter lid called Pickle Pipes and the Pickle Packer. These glass pebbles are perfect for small vegetable ferments in Mason jars and fit any volume, from a small jam jar, quart jar, gallon jar and more!
For Making Fermented Vegetables
Fermentology Sauer Stones take care of the most important rule of fermenting: keeping everything below the brine. These glass puck weights keep vegetables submerged to prevent spoilage in order to make delicious, probiotic-rich ferments, like sauerkraut, pickles, kimchi and more.
Designed for Mason Jars
Sauer Stones are specifically designed for fermenting in Mason and canning jars: only 1 fermenting weight is needed per jar. They fit perfectly into the mouth of the Mason jar and are heavy enough to push lacto fermenting vegetables below the brine.
Finger Grips for Easy Removal
Easily lift Sauer Stones in and out of Mason jars with convenient finger grips. Sauer Stones are available for wide and regular mouth jars, so no matter the size of your hand and the jar you’ll be able to get out your fermentation weight.
Non-Porous Glass
The quality of your fermenting tools and equipment matters. Sauer Stones are made of soda lime glass that is non-porous so germs can’t absorb in contaminate future ferments. The glass is food safe and lead-free to make the safest and most delicious ferments.
Perfectly Weighted
Wide mouth Sauer stones weigh 180 grams and are 2.8 inches in diameter. They’re sized and weighted specifically for fermenting in Mason and canning jars.
Part of a Suite of Fermenting Products
Sauer Stones are just one item of an entire line of supplies and equipment for fermenting by Fermentology. Traditional airlocks, waterless airlocks, airlock pumps, vegetable tampers, plastic Mason jar lids and airlock stoppers are all available under the Fermentology name.
Trust the Teal
You’ll know it’s us because of our identifiable teal packaging. All Fermentology products are made of high quality materials, including food safe glass, BPA-free and phthalate-free plastic, silicone and more. These items are designed in Canada by our in-house team of fermenting experts.

These are glass weights for regular mouth jars. We bought them to use in non- preserving jars, filled with culturing vegetables. They work really well for this purpose.

This product worked very well for my widemouth ball jars. These glass weights were more effective than a set I had previously purchased prior. I like the quality and the product for fermentation purposes. Would recommend.

These are very nice heavy weights. What I liked most was the storage box they came in because it's reusable and keeps your stones neatly & safely stored away. Also, the fast shipping of the product was amazing. The stones fit my large mouth jars but seemed to be too small once they got down in the jar but at the same time I'm not sure how well I could remove it once I got it in there if they were bigger. They are a little difficult to remove down in the jar, I used a long butter (case knife) to get it out which I tried a spoon but without success. I like these stones pretty much but I wish I'd ordered the ones with the grooves at the top for easier removal from my widemouth jars, but I will continue to use them, because I really like the feel and the heaviness of the weight. I bought these to make fermented cabbage because I've been reading about the health benefits to your digestive system, The natural probiotics it makes, How it's a great super food, I need that for my health issues. "Preservative free All Natural" That's what my goal is.

These are cool glass weights, and are nice for what they are. They're not extremely wide, though (so they won't break your jar or anything). Mine tilt easily in the jar, and some stuff floated past them to the top. One thing to remedy that might be to put a big leaf over the mixture directly under the weight. The weight would hold the leaf down (so the leaf would ferment) and the leaf would hold everything else down—I haven't tried it yet, though. Or, you could just make sure your pickles are not a proper shape for floating past a tilted fermentation weight. Or, maybe you know how to ensure that the weight doesn't eventually tilt. Maybe if it had some prongs or something to keep it steady by anchoring them in the pickles, it might not tilt.The weights are thick and heavy. They definitely seem to hold down what the stuff so you can't tell if it would be floating or sinking.

I truly love the design of these Fermentology glass weights because they were designed with dovetail angled grips to make them easier to grasp and remove from jars. Other companies make weights that have handles too, but many are straight or tampered, making them difficult to removed, which slip from your hand and fall back into the jar making a mess in some cases.

Three of the four were fine. The last one didn’t fit the regular mouth jar and chipped into my ferment when trying to remove it. Wasted a bunch of ingredients since there were small glass shards in them.Update: Reached out directly to the manufacturer regarding the one defective weight and they kindly sent a replacement. Now I have a full set of four again. Great customer service and a solid product.

These glass saurstones drop perfectly into wide mouth jars and do a great job of keeping your cabbage or other item your pickling submerged in the brine. Once you're done, they are extremely easy to hand wash or throw in the top rack of your dishwasher, although I would be concerned about cracking the glass if your water in the dishwasher is very hot. Did a great job on some pickled daikon I made.
