Description

A breathable Silicone stopper that acts as both a stopper and an airlock. Unique design allows CO2 pressure to escape but keeps Oxygen and airborne contamination out. This quickly became our stopper of choice for wine, and is a popular style used by numerous commercial wineries.

  • Fits 3, 5, 6 & 6.5 gallon glass carboys, 1 gallon bottles, growlers, and 500 mL flasks.
  • Replaces Stopper Sizes #6, #6.5, #7, #8
  • Stopper Measurements: 0.94" x 1.48" (24 mm x 37.5 mm)
  • The flapper stopper protrudes roughly 2.5" from the stopper to allow for easy assembly

Other available sizes include the Universal Breathable Bung and the Breathable Barrel Bung. All three size options can be purchased in one complete bundle with the Breather Bung Pack.

Easy assembly, Hope this flapper works
A dab of cooking oil on the red shaft and the parts easily join. flapper seals the vent holes, I'm just hoping they bleed before the CO2 pops the stopper out. trusting my first one.. We'll see

Disappointing
I used these bungs on a glass carboy and a PET carboy of syrah undergoing malolactic fermentation. I had another 2 carboys with regular airlock stoppers. I was away for 2 months. When I returned both carboys with this bung had a white film (mycoderma) on top. Any explanation? The buns were properly assembled and seated and the carboys were topped up. I did notice the tip of the bung insert was in contact with the wine. Could this cause the problem?

Life gets busy and airlocks get dry. This definitely helps with longer aging.

Carboy Breathable Bung
This item comes in two separate parts - the bung and the red flapper. I was only able to get the flapper pushed half way into the bung. After contacting MoreWine representatives a couple of times it was discovered that the trick was after pushing the flapper in as far as possible, to get it fully in one must moisten it with water and then pull it from the bottom twisting with a lot of force to get it assembled correctly. The item seems to be of excellent quality and the MoreWine associates I dealt with were helpful and excellent. Assembly instructions should be included.
