As some of you may know, I'm a bit of a Harry Potter fan. While I may not have cared for the final book (and I think part of that is because I'd been in the fandom as much as I was--I need to reread Deathly Hallows), I did love the community it inspired. Particularly fanfiction.
It is my hope to one day make it out to Universal Studios and visit their Wizarding World at some point. Until then, however, I have this lovely post from GeekMom talking about the intricacies of Butterbeer, Pumpkin Juice, and various potent potables available in Hogsmeade.
