If you crack open a beer this Fourth of July, history might not be the first thing on your mind. But for Theresa McCulla, the first brewing historian at the Smithsonian's National Museum of American History, the story of beer is the story of America.
"If you want to talk about the history of immigration in America, or urbanization or the expansion of transportation networks, really any subject that you want to explore, you can talk about it through beer," McCulla says.
