Used for berliner weissebier, the bowl is a low-slung, wide glass. This glass is all style, but works well with the berliner weisse when that style is adulterated by the woodruff or raspberry syrup. Then it is practically an alcopop
, and such an absurb drinking vessel makes sense.
Jacksons Ultimate Beer book shows the berliner weissebiers in a stemmed version of the bowl (almost a bolleke, which is really a cross between a bowl and a Trappist glass), and the additional elegance of the stem seems to fit well a berliner weisse taken neat.
