Simplify the fermentation process with the ViscoDisc Canning Buddies inserts! This innovative solution replaces weights to keep your vegetables immersed in brine.

Preventing the ingredients from coming into contact with oxygen is essential in the vegetable fermentation process (sauerkraut, kimchi, pickles, etc.).

Highly convenient, these Mason jar canning inserts help limit the risk of mould developing by keeping the vegetables immersed and out of the reach of air.


  • Allows you to improve the shelf life of your fermented food. No oxidation, less waste, and no discoloured vegetables!
  • Offers the same benefits as weights, but for a more affordable price
  • Allows you to maintain a uniform filling level
  • Can be used to drain excess liquid without spoilage
