Radler (Helles beer mixed with carbonated lemon soda) and Russ'n (the same, but with Weißbier) are very common here, and really tasty after a long bike ride to the Biergarten (hence the name Radler).
The two balance each other out if you don't want something THAT light and fruity or THAT strong.
and man-mosas are pretty popular in these parts - PBR and OJ
of course those are at the low end - some of these sound intriguing.
Sold a million of both before my buddies then declared a 6 gimlet minimum and we all got crocked
