About the product:

Handmade glass fermentation weights made in the USA! We created these weights to prevent mold in small batch lacto fermentation and pickling. These weights will let you put your fermentation on auto-pilot! No need to check your ferments daily or constantly push them down underneath your brine or liquid. Place one of our weights on top of your ferment and let it hold your produce underneath your brine. These weights will ensure your ferments remain mold free in an anaerobic environment!

The size of each weight will allow you to place these in and out of your jar with ease. They also allow carbon dioxide bubbles to escape on the side. Our weights are the heaviest available allowing you to only need 1 weight per jar!
