I'm currently brewing one gallon batches. I really want to delve a bit deeper into homebrewing and I'm finding that one gallon is kinda difficult logistically. I currently don't take hydrometer readings primarily because hydrometer readings take a fair amount of product per reading. The more I'm reading this forum though, the more I realize not taking OG/FG readings is a bad idea. I'm in an apartment so I don't have the space for a 5 gallon brew system and honestly I don't drink that much beer (yet). I realize I'm probably going to move to a 5 gallon system at some point when I do have the space and when I get better at brewing and I am confident enough to share with others but for now I think I still need to work in smaller batches. So I've been thinking of getting either a three gallon carboy or 4 one gallon carboys though I'm not sure which one is a better idea. The three gallon offers an advantage of effectively more bang for my buck timewise and hydrometer readings taking less of a dent out of my total beer. The 4 one gallon allows me to go wild with SMaSH beers or just more variety in general (which is important to me because I rarely drink the same beer twice in a row) but I'm in a similar situation as I'm in now with hydrometer readings taking a lot of beer. I'm kind of torn between the two ideas.. What do you all think?
