Small Ceramic Fermentation Weight
Product Review (submitted on February 20, 2014):
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.
