Distinguishing between Weissbiers

I noticed that I am having a little trouble distinguishing between Weissbiers here in Munich. I can definitely say that I do not enjoy Erdinger Weissbier. Otherwise, the rest taste super similar... except for some differences in aroma, and whether they have gone bad or not, it is hard to distinguish between them.

Now, I can of course distinctly taste the difference between styles of Weissbier (i.e Dunkel, Weizenbock, Regular). My favorite being the Dunkles Weissbier. I guess as time goes on, my palette will advance a bit. For now, I can enjoy the majority of them without thinking about it too much.

To be honest, after 5-10 sips, who is analyzing any beer anymore?
