 If you want to talk about immigration, beer is there. If you want to consider changing gender roles and consumer tastes, you can consider it through the lens of beer. And so it's a very malleable and engaging and kind of applicable tool for me as a historian and also an arena where you can do serious and really interesting research. But why the history of beer in particular and not wine or spirits or drinks in general? There's something specific about beer, it sounds like.
