Literally almost everyone on here makes/has made their own hooch of some sort. Homebrewing beer is pretty easy, but not super worth it from a price perspective, as even the cheapest brews are usually still about 50 cents a pour. However, upping that cost minimally, hell, even doubling it, will get you a fantastic beer for much less than you can buy in a store. Wine and mead are also popular, but I've no experience with them personally. Spirits require a still, and are thus complex, an possibly illegal.
