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.

Pleased with Viscodisc's

Being new to fermenting and not sure how long I would stay at it, I first started with whatever I could fine in my kitchen to use as weights. Now I have been at it for several months and I am hooked on fermenting I decided to try different products to see if they made fermenting easier. Viscodisc's did just that. They are inexpensive, easy to use, keep my vegetables under the brine leaving space for the ferment to expand. Fermenting is easier with Viscodisc's.

They do the trick!

I was a little skeptical about these inserts but they work just as I'd hoped for keeping vegetables below the brine!

The viscidisc canning buddy mason jar inserts work wonderfully - when I first say them I was not sure about them but they are amazing for keeping the vegetables submerged in the bring
