Fermentation Airlock, 3-Brew Airlock with 3-Brew Rubber Stopper with Hole for Brewing and Wine Fermentation

Easy to use: Simply install a perforated rubber stopper with a hole on the top of the fermentation vessel, insert the fermentation vessel into the rubber stopper, pour water into the bubbling fermentation device with the stopper, and cover to ferment the red wine.

One-way valve design: The bubble fermentation design with stoppers isolates air during the second fermentation process to prevent oxidation, so the entire fermentation process occurs automatically and the thermostatic chamber discharges without manual control.

High-quality materials: Our fermentation bubbler with a perforated rubber stopper is made of food-grade silica gel and high-quality plastic, safe and non-toxic, and is a good tool for food fermentation. 3-piece stirring valve
