There are three fermenters sitting next to my desk… An APA, Belgian IPA on day two…chacka ckacka pop chacka pop, and a Kölsch on day 5, a bit more laid back… blup. Between the three of them its a drum solo… Being a very part time musician I’m trying to discern patterns, you know new beats… the rhythm of the beer…(sorry Paul)… ;D
I use glass blow-off tubes in beakers for my “airlocks”. I used to keep my fermenters in the little room underneath the stairs (what we call Harry Potter’s bedroom). The constant bloook, bloook, bloook, in the quiet of the night irritated my wife. With multiple fermenters, the out-of-time cacophony of bloooking drove her crazy (she is a pianist). We bought a window-shaker air conditioning unit, converted one of the bathrooms into the fermentorium and gave Harry his bedroom back.
I loved the blooking myself, but as the saying goes, “When Mama ain’t happy, ain’t nobody happy!”
That goes double for lack of sleep.
