DIY Essentials: Making a Fermenting Jar

Andy Anderson !


As you probably know, eating fermented veggies can be very healthy for you.
I shopped about on Amazon, and found that you can spend 50 bucks or more on fermenting jars; which are basically modified canning jars. So, in the spirit of American ingenuity, we are going to make our own using a few parts from good ole’ Amazon.

And the price is only $9.79 per jar, and if you use my hack for the fermentation weights, that brings the price down to $4.79 per jar. And do not forget that you can use them over-and-over again

So, you ready… Let’s get into the kitchen. Or, in this case the workshop.

How to Make DIY Essentials: Making a Fermenting Jar


  2. 1, 2, 3
    A quart-sized mason jar with a sealing disk and screw-down ring.
    I picked some up at a thrift store for a buck each.
    FYI: Make sure that they are large mouth canning jars.
  3. 4.
    Grommets made from food-grade silicon. I found the perfect ones on Amazon for $7.99 for ten.
  4. 5.
    Plastic airlocks to vent the fermenting veggies. I played around with a few and found these to be the best., $8.99 for a set of six.
  5. 6.
    Fermentation weights to keep your veggies under the brine. After several misses I found these for $20.00 for 4. This is the most expensive part of the kit, but I will show you a hack if you do not want to purchase them.
    A drill with a 1/28-inch bit…
    Or, a friend who has a drill with a 1/2-inch bit…
    Or, a pistol that takes .22 bullets, so you can shoot a whole in the lid…
    Up to you.

    Drill a hole in the middle of the sealing disk.
    Extra Scooby points if you get the hole spot in the middle… Ops… my bad.
  8. Add the grommet to the newly-drilled hole.
  9. Stick one of the airlocks into the hole with the grommet.
  10. Place your veggies and brine into the jar, and then add the fermentation weight. If you do not wish to buy the glass fermentation weights, then crumble up a piece of wax, or parchment paper, and use it to push down the veggies into the brine. If you use the paper hack you will save 5 bucks per jar. I do; however, prefer the glass weights.
  11. Screw the top back on, and wait for the veggies to ferment…
  12. Chef’s Note: It goes without saying (but I am going to say it anyway) that you can use larger jars for your formatting. The size I am creating in the photographs is what I call my “test batch” jar. It is large enough to use when I am experimenting on new fermenting ideas, and if I like it, I will move to a larger jar. Just remember, the larger the jar, the longer it takes for the fermenting process to take.
  13. Keep the faith, and keep cooking.
