I've been home brewing simply for years . By that I mean traditional from grain, fermentation buckets and bottling after priming. Recently, I have taken the plunge on a Fermzilla with pressure kit. I'm looking to ferment and serve, so using the kit as an all-in-one. I've a couple of scatter gun questions about this kit I'm hoping you can help with. 1) At what point do I take change the collection chamber to remove the trub/yeast? How do you tell? Is it 1 day - or many days? 2) What PSI should I set the spindling valve to pressure ? My cellar keeps a nice 65F to 68F temperature and I like a stout. 3) Can I expect to pour straight from the vessel? Does the PSI need to be increased as the liquid drops? 4) I have a soda stream style CO2 bottle. Will this suffice? Do I need a full CO2 tank? 5) Will I need a full CO2 tank to bottle using a beer gun? Sorry for so many questions, but hopefully I can piece together the parts and gain a better understanding of the direction I'm taking. Many thanks in advance.
