Breathable Silicone Stopper

Fits 3,5,6 & 6.5 Gallon glass carboys and 500 ml flasks. 

DOES NOT FIT BETTER BOTTLES.  

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. Quickly became our stopper of choice for wine. Used by numerous commercial wineries. Also has great application for beer ferments: Will create a vacuum if fermenting wort cools (as opposed to pulling water in from your traditional airlock.) Air tight seal is great for extended fermented lager when CO2 production is still present but very slight.

Dont buy unless you just want a stopper to keep out dust
Just got these and I'm not sure at all how they would ever work as an airlock, or a stopper. The holes don't seal at all. There are small pieces from the mould that stick up and prevent the top part from creating a seal, thus you've got open holes. I wanted these to bulk age wine and mead but it looks like they will be for a primary ferment where I need a bug proof but open fermentation.
