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 ethanol alcohol.
Step 1: Gather the parts.
Parts that you will need:
-3 inches of 3/8 inch hose
-Hot glue or other sealant
-A water bottle
-Clear film canister (usually available at any place that develops photos, ask for one)
Tools that will come in handy:
-Drill with 3/8 inch and 1/2 inch drill bits
-Belt sander/metal file/sandpaper
