You will need to start with a heavier ale to get the hang of things. An upscale beer store or deli should have all the equipment/ingredients you need, plus some literature . . . make sure you do your reading first.
As a person who cooks quite a bit, I understand that usually things turn out best if you make more - for instance, when I make lasagna, I never make fewer than three at a time.
But I was thinking about starting smaller than 5 gallons - 2.5 to 3 or so, just to get the hang of it. Is it safe to bottle the stuff when it’s still fermenting a bit?
There is a beer making supply place not super close, but I can get there.
