My 6.5 Gallon Big Mouth Bubbler just arrived, and upon unboxing, I have found a piece that boggles me. I presume it is for the top.
The lid has a smaller hole for the bung and bubbler, and a very convenient screw-on cap for storage.
HOWEVER, there is another piece made of clear plastic that sort of looks like a jello shot cup. I see it has some threading, some “scuppers” along the rim, and a hole along the threading wall.
I have no idea what this is.
Is it some sort of new-fangled airlock? Am I supposed to trust my wort to this?
I have a bung and proper 3-piece airlock for it. I am confused as to what to do with this extra part.
I plan on brewing this weekend, so any quick response would be greatly appreciated.
