This simple CO2 regulator is used to slowly release CO2 gases from the fermentation process of wine or beer using water and a few parts that can be found quite easily. It works by allowing CO2 to get out of the fermenter without permitting oxygen to enter. If oxygen was to get into the fermenter, it would stop the yeast from making that delicious ethanol alcohol.

SUCH a bad idea.
One piece molded airlocks that you can sanitize effectively cost exactly $1.10 online, and are just about infinitely reusable. You can often find them even cheaper than that. This thing with nasty glues, rough spots to harbor bacteria and mold, and a used cork, ain’t getting near any batch of beer I’m brewing.
Beer ingredients: $25-50
Brewing time: 5 hours of work, a week of fermenting
Having a batch of tasty beverage go bad due to DIYing a $1 part instead of buying it: stupid
I’m with cybertrash on this. While I’m all for making your own brew ware, this doesn’t really make sense to me.
The real thing is *so* cheap…
Also, oxygen getting into the fermenter doesn’t “stop fermentation”; there’s always oxygen inside a fermenter, especially at the beginning when the fermentation is at its most powerful! The idea of an airlock is to prevent the gases inside the fermenter from building up to the point that the container explodes, and secondarily to prevent funguses and bacteria from getting in.
This is a dumb idea created on the wrong principle.
I’ll have to give my “me too” on this one. Those things are ultra cheap to buy and I’d sooner buy one than waste a year’s harvest of grapes.
I too agree… if you really want a ‘diy’ solution, find a foodsave tube that fits perfectly the neck of your carboy, or grommet in your bucket, whatever. Heat the tube under running hot water and snug it in there, then submerge the other end in sanitized water.
