Hello friends, I'm a newbie brewer and I'm just gearing up to do 5 gallon batches. Looking ahead, I want to eventually dive into all-grain, but I am undecided about larger batch sizes. Please help me with these questions. 1. I just bought a Tall Boy 10 gallon. My stove top can boil 4 gallons in it, I'm in fact doing it now, lol. Does that mean that I can do 5 gallon Brewers Best kits indoors? I did also buy a Darkstar 2.0, so I'm still in business outside either way. 2. Should I drill holes in the Tall Boy at some point to add a thermometer and ball valve or should I shop for a new kettle down the road? How will this kettle fit into my evil plans as I go to all-grain and possibly go to bigger batch sizes? 3. Should I swap out the regulator in the Dark Star or will the 5 PSI regulator that came with it be sufficient for what I'm doing? Thanks...and CHEERS!
