The typical method for taking draft beer home from a bar, brewery or store is a reusable 64-ounce glass growler jug. But the growler has flaws, which has led Oskar Blues Brewery in Longmont, Colo., to develop the Crowler, a 32-ounce can into which keg beer is dispensed. The can is sealed, and you’re good to go. Why is the Crowler better than a growler? Ted Kenny, the owner of Top Hops Beer Shop on the Lower East Side, which recently installed a Crowler machine, said it’s lighter to carry, won’t break, can be taken on a boat, is impervious to air and light, and will keep the beer fresh far longer than the 24-hour limit you get with a jug. The cans can be used only once, but they are recyclable: Top Hops Beer Shop, 94 Orchard Street (Delancey Street), 212-254-4677, tophops.com.
