FERM-RITE BUNGS ARE MADE FROM 100% FOOD GRADE SILICONE

Our Regular Silicone bung fits 59.9  gallon French/American oak barrels.

Carboy silicone bungs are the original breathing silicone stopper that acts as both a stopper and an airlock. Ferm-Rite design allows CO2 pressure to escape and keeps Oxygen and airborne contamination out.  

Our bung stays in the barrel only releasing pressure when its time, after pressure is released they continue to stay snug in the barrel keeping your wine SAFE from oxidation and other contaminants!

When your barrels begin to saturate the liquid level inside the barrel drops causing a suction to occur inside the barrel which makes our bung work just like a SOLID

Our bung keeps your wine safe from fruit flies and other foreign objects increasing the life of costly filters! 

Ferm-Rite is UNDER NEW OWNERSHIP and is  a family owned and operated company located in Lodi Ca., which is considered the Zinfandel capitol of the world.
