It's genius for sporting events and picnics, where the can-as-a-cup convenience is prime, but not without a caveat. Home experiments with Sly Fox's crisp Helles, released for retail in 360 cans this week, revealed one complaint: the opening creates absolutely no head unless you shake the can first. (Not recommended!) Better to just pour into an actual glass and let this fine lager bloom like the golden spring brew it is.
