Glass Weight

$3.15 $

Use the glass weight in Airlock Fermenters to submerge your ferments under brine. Ideal for sauerkraut and kimchi and vegetables that bob above the surface such as pearl onions, hot pepper rounds, cauliflower or broccoli florets, and cranberries. Not needed for asparagus, cucumbers, or other vegetables that can be packed snugly and held below the brine. Not needed for fermented drinks, batters, or grains.

Ferments made in 2 L, 3 L, and 5 L jars may need more than one glass weight.
