Along with Sunday liquor sales, the happy news to come from a comprehensive rewrite of the city’s liquor laws is that now brew pubs, liquors stores and full-service grocery stores will be able to sell growlers, the reusable 64-ounce containers that are all the rage among beer aficionados. (Up until now, only the city’s three breweries could sell them.)

Great, right? Sure, but there’s a catch. The sale of single beers is banned in Mt. Pleasant and wards 2, 4, 6, 7 and 8—and that ban covers growlers. According to Bill Hager, a spokesman for the Alcoholic Beverage Regulation Administration, while brew pubs and liquor stores across the city will be able to sell growlers, full-service grocery store will have to abide by any single-sales ban that applies to them.

Of course, the city’s patchwork of laws regarding single beers is a little more complicated than just that. Retailers in Ward 2 and 6 can apply for exemptions to the ban; the Whole Foods on P Street, for example, is allowed to sell single beers. (If you’ve noticed, it sells fancy single beers.) So while those will be able to offer growlers, full-service grocery stores in Mt. Pleasant and wards 4, 7 and 8 won’t.

Who thought getting a beer would be so damn complicated?
