Description

We recently discovered this premium breathable silicone barrel bung and were immediately impressed with its robust design and features. To start with, the built in tabs really help make bung removal effortless. But where the bung really shines is in its two-piece design. When set to the open position, the bung acts as an airlock and allows the release of CO2 while maintaining a seal against oxygen coming in. This makes the bung ideal for alcoholic or malolactic fermentation in barrels or tanks. When fermentation is over and you no longer want the bung to "breathe" out, you just push the center cap into the bung to create a firm seal and the FE497 becomes a solid stopper!

Fits most 30 and 60 gallon barrels as well as the hole in the lid of most Variable Volume tanks!

tapers from 1 7/8" to 2 1/4" diameter

Good fit for Vadai 32 gal barrel
The Vadai barrels come with a wooden bung that does not seal. The silicon bung that "breaths" works very well.

Great accessory for barrel aged sours
We use the breathable bung for our barrel aged spontaneously fermented Belgian style sours, aka lambics. The bung is really well designed. It provides enough counter-pressure (even when in the open position) to not let any air in when the fermentation is inactive, like during colder periods. The fact that it is easy to clean is really good as a highly active fermentation will push the foam and yeast through the opening (see picture).
The bung does its work as the spontaneous fermentation kicks in for our Belgian style lambic.

These bungs work great and eliminate the need for bubblers on my still fermenting barrels.

Great for barrels
These are great for spirit/wine barrels 15G or larger. Easy to clean though they do get stained over time.

Can't live with out them, had other silicone bungs pop out during an unexpected secondary fermentation. well worth the price to prevent blown out end caps

Great Product
The Bungs fit great! It is always nice to know it will release any pressure if any fermentation takes place, no barrel explosion potential.

Wooden Cask, Averill House Vineyard
We gave these a shot on two cask, so easy to use. Not only do they fit great but interim tasting is easy with the center vent. Smacked it in with a mallet then popped the center piece in for a fabulous fit.
