Weigh down your fermented vegetables using this ceramic fermentation weight. Keeping vegetables weighted under the brine keeps the vegetables from drying out and can help prevent mold.

  • Approximately 3 in. (7.6 cm.) diameter
  • Fit most standard wide-mouth style canning jars (quart and half-gallon sizes)
  • Two interlocking pieces for easy placement
  • Food grade ceramic
  • Lead-free
  • Hand wash with vinegar or warm water (do not use soap)


Instructions for use:

Rinse well before using, with vinegar or warm water. Do not use soap. Fill the fermentation vessel with the prepared vegetables leaving appropriate headspace, place the ceramic weights on top of the vegetables to ensure the vegetables sit under the brine. Cover the vessel if desired. Allow the vegetables to ferment. Remove the ceramic weight prior to storing or consuming the vegetables.


Composition of the Clay:

  • Red Art, a base clay containing iron oxide, salt, and feldspars  
  • AP Fire Clay
  • Gold Art, a base clay
  • Om4 Ball Clay   
  • Feldspar
  • Grog 


Additional Manufacturing Information from the Craftsman: 

I use a tried and true clay recipe I can trace back 80 years through various craftspeople I have known over the years.  

The weights are not glazed but rather fired 2,350 degrees using an oxidation technique. This process vitrifies the body of the clay making the molecules so dense that water and other elements cannot penetrate the surface thus rendering the clay food safe.

    • Can I use this instead of the glass weights in the 1/2 and 1 gallon glass fermentation containers?
    • You may use this or the Large Ceramic Weight in the glass Fermented Vegetable Masters. The Large Weight may be a better fit for these larger jars, but these small weights will certainly work, maybe 2 sets in one jar, distributed over the surface, would be best.

Perfect size for wide mouth jars! Review by clmax
These small ceramic fermentation weights are perfect for standard wide mouth canning jars. I'm currently using them to make a small batch of sauerkraut and its doing a great job keeping the cabbage below the brine in the jar. I could see a great benefit if they were just a bit heavier to keep larger veggie ferments down easier but most of the time, these are great. (Posted on April 17, 2014)
Love these new ceramic weights Review by Janice
These fit perfectly in a half-gallon mason jar. For me they work even better than the glass weights as they stay where put without shifting around. (Posted on March 18, 2014)
Product is okay. Review by slt44
Seems to work fine on most veggie ferments. Other times the weights do not seem heavy enough to keep some veggies submerged. (Posted on March 16, 2014)
Small Ceramic Fermentation Weights Review by LC
I thought these might work based on the description but they are a little too small for half gallon wide mouth mason jars. Since they are zig zag in shape, you can fit them in the small mouthed jars. It did not cover the cabbage fully so I had to add my glass weights too.
I could fit three pieces in the half gallon jar. I will have to buy the large size to see how they will fit. (Posted on February 28, 2014)
teensy-weensy Review by Bekah
I ordered one of each size. I also expected them to be bigger, based on the product descriptions and the previous reviews, but they do seem quite a bit too small either for wide-mouthed jars (the smaller ones) or for crocks (the "larger" ones). The crock size in particular is ridiculously puny for the task. I will try them, but I don't think I will try them on their own because I don't want to risk their not working and ruining a whole batch or much of a batch.

Response from CFH- These weights were specifically designed to be used with the Fermented Vegetable Master. Please contact Customer Support with any problems you encounter. (Posted on February 26, 2014)
Smaller than I expected Review by Cathy
Based on the review I read, I expected these to be bigger. Having tried them, they seem too small for wide-mouthed jars (quart-size). I had cabbage that floated above them, escaping from the sides or the crack, so I still had a layer of cabbage at the top that might get moldy. I love the idea and will probably use them, but I rated the quality and value a little lower because they don't seem to be doing as good of a job as I had expected. (Posted on February 21, 2014)
Perfect for small batch fermentation Review by Richard
I like to ferment several small batches of krauts, so I can make them all different, instead of one large batch. These weights are perfect to use in a wide mouth mason jar. I'd definitely recommend them. Since they are in two pieces, they are easy to add and remove from the jars. (Posted on February 20, 2014)
