Our fermenter requires a lid gasket and rubber stopper with this product.
A double bubbler offers advantages that other airlocks simply can’t. It will show the difference between the inside air pressure and the outside air pressure (a great way to gauge fermenting activity), and it can also prevent “suck back” (a term used for when liquid in the airlock is sucked into the fermenter due to temperature changes). Not to mention watching the bubbles is a great way to pass the time while you’re waiting for your beer to complete fermentation.
To create an airtight seal with our fermenter, you must use a lid gasket and #2 or #3 rubber stopper along with this product. Always sanitize (inside and out) before using.
2. Adding The Airlock
After you have made your beer and added the yeast. Tightened down the lid, then add the airlock.
3. Filling The Airlock
After the airlock is firmly in place, add water to the fill line(s). Sanitized water or alcohol (like vodka) is preferred. (fyi. if need be, refilling it with regular tap water should be fine).
4. Removing The Airlock
Remove the airlock (and/or loosen your lid) BEFORE opening your tap for any reason. Completely remove the airlock before bottling your beer.
WARNING: ALWAYS REMOVE THE AIRLOCK WHEN OPENING TAP, OTHERWISE LIQUID FROM THE AIRLOCK WILL WIND-UP IN YOUR BEER.
