Years ago going through university, a bunch of us started to make our own beer. It actually worked out quite well and it got so big, competitions were held.... beer is very easy to make and I kept a log book so that I could see how one recipe compared to another. I ended up making so much that we’d have parties and all the beer drank was from batches that I had made. One big advantage for a university student, it was real cheap. I remember joking with the other guys that the cap represented about 25% of the cost.
Or you can go to a brew your own place commercial place... there are lots of advantages to doing it there and I’ve now done it several times with an outlet in my town. They at least are nicely set up for the bottle washing and the wort can brew away in a controlled environment where the smell (which isn’t all that objectionable) can be exhausted away.
My grandfather made his own beer during prohibition.
