How it works:This shape is at once a feat of sensible design and lyrical artistry. Pouring a Belgian ale releases its gases, so it gives rise to a fluffy, marshmallow-esque head. Contrary to popular belief, beer foam is nothing to be disdained. Garrett Oliver, Brooklyn Brewery's brewmaster, explained that a head concentrates the aroma, but just as importantly it's part of the "mouth-feel" of beer. Swallowing a bit of foam with the fluid gives beer "a rounder character in mouth than it would have otherwise," he said. Of course, you don't want a whole mouthful of fizz, so the glass's tapered contour and tight collar serve as a built-in foam-blocking mechanism, forcing the head to sink back into the bulbous base while you tilt it for a sip. Tulips usually hold less than the standard pint, but bear in mind that many of the intended beers are powerful potions.
The verdict: At the Sunset Grill, when a Duvel was poured, the foam billowed up immediately, like Alka-Seltzer in action. The pale golden tint makes Duvel "deceptively" strong, but it's wise to remember that the name of the popular Belgian ale that translates as "devil."
The wide rim offers a huge whiff of vaguely fruity, somewhat zesty tones.
