1 Gallon Glass Fermenting Jar - Airlock Lid

The fermenter's upgrade: a 1-gallon wide-mouth glass mason jar with a one-piece airlock lid that lets CO2 escape while locking oxygen and contaminants out. No more burping jars or rigged-up balloon lids — sauerkraut, pickles, kimchi, hot sauce mash, and kombucha ferment cleanly with a fraction of the failure rate. Built-in airlock system — releases fermentation gases automatically while blocking oxygen, mold spores, and fruit flies Full 1-gallon capacity — big batches of kraut, pickles, or kimchi in one vessel Extra-wide mouth — pack vegetables tight, fit weights easily, and clean by hand without a fight Thick, clear glass — watch the bubbles work without opening the seal 1-pack or 2-pack — stagger two batches so something is always ready The set-and-forget way to ferment. Fill it, set the airlock, and let it work.
