Wide Mouth Mason Jar Lids with Airlocks – 4pc

  • Happy, Healthy Ferments- most vegetable or fruit fermentations are anaerobic and prefer to remain free from oxygen. As gases are produced in the ferment, they replace the air left in the headspace by pushing it out of the airlock, reducing the risk of mold and unwanted contaminants in your jars.
  • Fits all WIDE-MOUTH mason jars – from 1 pint to 1/2 gallon you can experiment with small-batch or larger batches for your favorite recipes.
  • Easy to use – Just fill the airlock to the waterline, place into the slot on the lid and screw the lid on tight.
  • Worry free fermenting – No more worrying about burping your ferments to let out excess gas, or fretting about mold contamination. Just set it and forget it!
  • Fun and healthy hobby –  Ferment your own kimchi, pickles, sauerkraut, hot sauce, garlic, and much more!
