I’ve been making alcoholic beverages at home since I have been of legal age to consume them. I started out making mead, then switched to beer when I moved to a house across the street from a beer-brewing friend.
I won’t go into much detail about brewing, but I should mention that temperature control is pretty important. I was taking a couple of classes with a friend, and we needed to come up with class projects. We decided to combine the projects and build a temperature controller for homebrewing.
