I didn't do it at home but many years ago there was a business in Milton called Hogs Head Brewery where you could make your own beer. A couple of friends and I started playing around and developed our own recipe. It worked out so well they actually added our recipe (called Bignell's pilsner) to their book of standards and took out a full page add in the local paper with my picture 😊.
If there is a similar place close to you I think I would try doing it using their equipment rather than buying and maintaining all your own, that will give you a lot more options than trying to do it at home. Anyway, good luck and have fun with it, nothing more rewarding than DIY 😊
