The parts to make your own fermenter, a lidded jar, airlock and airlock grommet and drill with bit

Fermenting has become more popular and less mysterious over the last decade. While many cultures eat fermented foods as a part of their diets, we Kiwis have been a bit slower to catch on (as long as you don’t count beer!). While living in Scotland we found an affordable little fermenter and dabbled with making sauerkraut a few times, but it wasn’t until we were back home we started making it regularly.

At that stage, we realised that the little fermenter we brought back with us wasn’t big enough for the regular use we were giving it and started looking for something bigger. Alas, the price was much bigger too, so we got creative and went hunting for a large lidded jar to make our own fermenter at home and for a fraction of the retail price.

How to make a Fermenter

What you’ll need:

  • a large glass jar with a plastic lid (try your local op shop!)
  • an airlock grommet
  • an airlock
  • a 15mm drill bit or drill bit the size of your airlock grommet
  • a drill.

Time needed: 5 minutes

Steps for making a fermenter

  1. Secure the lid and drill a hole using a 15mm drill bit or one the size of the grommet)

  2. Clear the plastic shavings from the hole.

  3. Insert the grommet in the hole in the lid
