Beer. Preferably an imported German Weisse or Weizen (I'm not sure on the difference, both are wheat beers), the American micro-versions i've had come across to as being too watery in texture. More specifically, Neumarkter Lammsbrau Hefeweizen (Helles, not Dunkles or Doppelbocks, I'm not into dark beers). Unfortunately, I've not seen Lammsbrau ion the states, and contend with the Tucher brand (which I've consumed more of than any other brand) or whatever else I find stocked in the import section of my local liquor stores.
The best beer I've ever had was an unfiltered Lager, from the local brewery of a small town between Erlanger and Forchheim, and east of autobahn A73 (I no longer recall the name of the town or brewery).
I try to avoid most big brand name American and Imported beers, as most of them are (IMHO) little better than pisswater, and therefore a poor representation of the Pilsner which most are based on.
