As a beer reviewer who always drinks from a glass, I was skeptical that cans of different shapes would have a noticeable effect on flavor. Pouring beer into an open vessel allows a drinker to parse the flavors of hops, barley, and yeast. I wasn’t concerned about any tinny flavors from the cans, that problem having long been solved, but drinking out of a can struck me as more about convenience than taste.
