I’ll post a recommendation on a beer, but make it a very specific one, in the category of Hefeweizen or Weissbier.
I strongly recommend the Franziskaner Hefe-Weissbier.
My wife and I have done our share of hut-to-hut moutain hiking in Germany, Austria, Switzerland. The best part is those huts usually have good cold Weissbier. So I’ve had my share of good European Weissbier!
I found this is one of the best tasting Weissbiers conveniently available in certain CA markets (Try Whole Foods)
Of course, Weissbier is best served cold on a hot summer day. Some like it with the lemon wedge; others do NOT. Whatever the case, Weissbier is NOT a beer for a cold day.
Also, if you like your Weissbier w/a lemon, be sure to add the lemon AFTER you poor; otherwise, the acidity of the lemon will prevent a good head from forming on your Weissbier .
There are those who claim that Paulaner is better, but I do not agree. It is good, but not as good as Franziskaner.
