There are lots of cheap, weak, untampered glass fermentation weights on the market. They work, but I was sick of opening my ferments and finding them cracked in half. No one else makes tempered weights because it’s really expensive, but I wanted to make a product that lasts, for people who intend to use them for a lifetime. I made these for home fermenters who want the highest quality possible (And are willing to pay for it).

These heavy, tempered glass weights perfectly fit into a wide mouth Mason jar to hold your fermenting vegetables under the brine and press out any air pockets, leaving a tiny space around the edges to let out fermentation gasses.

Most competing discs are not tempered, which is much cheaper to produce but less safe. Air bubbles and other imperfections in lower quality glass cause them to crack during use. If you fill your jars up to the neck, one weight will perfectly cover your ferment. You can use more than one weight if the jar isn’t completely full of if you want to displace more brine to bring the level up to the neck of the jar. With more active ferments, you might not want to fill the jar into the neck to avoid overflowing brine.

Then you will probably want to use two weights.
