I brew in 1 gallon batches too, I'm just starting a souring program now, will be hard to do but it can be done
How do you deal with the kettle? I use a cooking one (not designed for brewing I mean) that I bought only to brew beer but it doesn't have a tap or anything at the bottom, obviously, it's for cooking, but it would be really useful to have one to drain the wort and avoid part of the turb getting into the fermentor, I use a roughly 2.3 gallon kettle (9L) but are there any specialized kettles for brewing? Like with a tap at the bottom, a couple litres more would help me when making big beers too
