I feel guilty saying this, but the Fermzilla was a bit of an impulse buy for me. Had decided to go with the Guten fermenter, but it was out of stock. Happened to be looking at this forum when news broke, I managed to get one first release. Am quite happy with it so far! (And before anyone spruiks the benefits of stainless over plastic, I'll add it probably won't preclude me from getting a stainless conical down the track.)
I'm six days into my first fermentation, yeast has begun to flocculate and my collection jar is pretty full. Will remove tonight, but am wary about re-attaching.
If I do reattach, I'll basically do using the same principles as a counter-pressure bottle filler. It'd involve:
- attaching a carb cap to the jar, attach jar to bottom of unit, purge with CO2, then under a small amt of pressure feeding the beer out through the floating dip tube into the jar via the carb cap
- gently loosen jar from the fermenter to allow CO2 to gradually escape out the lid
- when full, tighten the jar and open butterfly valve.
But I'm conscious that'll let in a small amt of O2.
Pretty sure the benefits of collecting additional trub won't be greater than the risks of additional O2, but interested in the views of others...
