Looks interesting, I don’t have that but recently bought the Spike Flex + fermenter that will ferment under pressure (I think 15 psi ). Cost me about 400 bucks. I was interested more for brewing IPA and NEIPA to do closed transfers under pressure to keep the O2 out. I have been reading up a bit on fermenting under pressure but haven’t really seen anything that compels me to do it. With the Spike my plan would be to let it ferment as usual until maybe the last few days (or after adding hops to the fermentation) then close off the blow off port and let it build up a little pressure at the end.
It would be nice to have a 10 gal fermenter ..... seems I always see 7 gal or 14 gal out there in stainless. I would not look forward to lifting that beast into my chest freezer (temperature chamber) when its full though.
