is it the shape? the large mouth that allows you to see and smell the beer? the rounded smooth bubble on the glass that is a joy to pick up?
the size? 4 ounces more than your average american pint, means less trips to the bar. and, well, just more beer. who doesn't like that?
is it the tradition? any pub in the British isles will be pulling your pint into an imperial glass. it's transportive. and we think nothing looks as handsome, as a dark stout, with the creamy bishops collar, poured properly into the right glass. its a taste of home.
