ALL-IN-ONE - Complete fermentation airlock system releases pressure without allowing oxygen or other contaminants into your ferment.

Not all mason jar fermentation kits are created equally! We have taken the time to custom design all of the Sauer System components to get the sizing and function just right for a durable, safe fermentation kit that is easy to assemble, clean and use over and over again. Each kit includes 4 complete airlock lids specifically designed for mason jar fermentation.
Includes 4 of each of the following: Tough Tops Durable Lid, Supreme Airlock, Silicone Grommet, Silicone Gasket, Silicone Stopper.

FITS ANY REGULAR/SMALL MOUTH JAR - Will work with Ball, Kerr, Bernardin. Any brand of "Regular Mouth" Mason jar in pint, quart, or half-gallon.

BPA-FREE, DISHWASHER-SAFE - All components are certified BPA-Free and custom made for a perfect fit.

TOUGH TOPS INCLUDED - The best-selling Masontops Tough Top is the lid of choice for this system. Built to last, unlike flimsy "plastic storage caps" that bend and crack.

TRUST THE TEAL - Unlike "homemade" kits, Fermentology products are all inspected and verified to be high quality, durable, and safe for you and your family.
