You promise to bring your best dance moves. We promise to mix the best beer cocktails. It is D.C. Beer Week. It is time to celebrate, specifically the Adamstown, Pa.-based Stoudts Brewing Company and the Philadelphia-based Blue Coat Gin and Vieux Carre absinthe. Come one, come all: Wednesday (Aug. 20), starting at 5 p.m. Channel your inner Elton John. Think “Philadelphia Freedom,” that 1975 ode to Billie Jean King and her start-up tennis team. Bonus points to those who come in those John-inspired, killer sunglasses, long before he was Sir Elton John.
