Some people find beer interesting. The history (e.g., aided in survival of crew on early trans-Atlantic travel), the various methods. I get giddy when I hear the word "wort". Many people enjoy brewery tours, every one is a little different. I've been on brewery tours more times than I can remember (😁🏴☠️) and a brewery tour doesn't work well without a brewery. Oh and the yummy taste, especially those double and imperial IPAs and stouts!
