Magnus watches, frankly a little fascinated. This kind of thing has never really been on his radar or in his world before. His primary association of booze is that it's a crutch, and one that he has a lot of really complicated feelings about. Oh, he's had his experimentation with drunkenness -- who hasn't? -- but he was still alive at the time, and it's not like he and the other street kids were trying to make fancy little cocktails or anything. He's never really thought of it as a fun thing to explore flavors with, except for when Aegir was blabbering on ceaselessly about his mead microbrews, and that was just a quest hurdle to weather.
