So i have a small chest freezer sitting in my basement, been there since i bought two uprights. Anyways I want to make it into a keezer/fermentor. I have a couple questions I'd like to ask all of you. I'm only gonna make it a two draft system but i will put the 3 way gas distributor just in case I add a third keg (if i can fit it). I'm the only one in the house that drinks beer, but we travel extensively in the summer. So my plan is to make 5 gallon batches and bottle 2 gallons and keg the rest. Ive been debating whether or not i should just get 3 gallon ball lock kegs or 5 gallon. I lean towards 5 gallons because in the winter when we dont travel much i can just fill a growler and take it with me when we go visit friends etc. But if i only fill it with 3 gallons how will that effect carbonating the beer with the 2 gallon head space, also will this effect how fast i go through my C02? Next question im only doing 2 taps right now, will a 5lb bottle last a while or should i go with 10lb? I feel like im missing something else i wanted to ask. Anyways thanks for the input!
