Wide Mouth Gallon Jar Lid w/ Hole and Grommet

Our reusable lid for a wide-mouthed jar is perfect for any fermentations you have going at home, from kombucha to sauerkraut to kimchi. We drilled a hole in the lid and put in a rubber grommet, perfect for an airlock. 

Using an airlock allows any pressure developed during fermentation to escape without allowing bugs, air, or other things that can harm whatever you are fermenting in your 1 gallon wide-mouth jar.
