I was about to start a post about something similar, saw this so thought I'd jump right in, unfortunately not with advice but more questions.
So... I've been sat on a stout for a few weeks now, fermenting away nicely, probably didn't have enough yeast, shoulda made a starter, anyway.... it's a mocca stout, has some 85% fancy chocolate in and a nice jug of freshly ground espresso added too, grain used included some chocolate, roasted barley and a cafe grain, this has created a nice tasting brew, planning to add some vanilla at the end.
My plan all along was to keg this batch using beer gas, 70% nitro, 30% Co2. I've been spending quite a bit whilst locked down and bored browsing beer sites on equipment, this includes a 19ltr corny keg, Co2 and nitro regulators, small 5ltr growler setup, even bought a new fridge to play with lager fermenting and keg storage, picked up 2 x 10ltr gas bottles yesterday so I can do nitro and force carb IPA's with C02... if my wife finds out how much I'm spending I'm in trouble.
The thing is, after buying all this stuff, I have to admit not really knowing what I should be doing. I've got force carbing IPA's in my head okay, but I have to admit to not being too sure what I do with the Stout. I'm thinking just keg it, chill, pressurise with nitro beer gas and pour, but something is telling me I don't have it quite right, not sure what it is, just a niggle, maybe I've read too much or watched too many you tube videos, I might be over thinking things, so any comments would be appreciated.
If there is anybody there who does this a lot, please give me a steer.
Cheers.
