Not every beer drinker is a frat boy at heart, but that doesn’t mean an aesthete of the brew can’t get primal now and then. Alan Eames, author of Secret Life of Beer: Legends, Lore & Little-Known Facts, has traveled around the world exploring the origins of the suds, from Egypt to Brazil to Peru, earning himself the nickname “the Indiana Jones of beer.” At the newly renovated U.S. Botanic Garden Conservatory this evening, Eames will present “Of Women, Bears, and Beers,” a lecture that purports to examine the relationship between “grain, women, and the human experience.” (But it kinda sounds like a drum-banging, less crass version of The Man Show. With bears.) Following the lecture is a beer tasting and some time allotted for a tour of the conservatory. Take in the flora with your beer goggles on at 7 p.m. at the U.S. Botanic Garden Conservatory, 100 Maryland Ave. SW. $15. For reservations call (202) 226-4082. (Tricia Olszewski)
