Kölsch. Surely the must elegant of beers. The most refined. Hence the fancy stemware. Apparently an ale but taste a lot like lager. Kind of lagery on the nose with a bit of sulphur and yeast. Pale as you like, with all the dryness and some of the fruitiness of white wine.
There is a certain aura around it; stories about Irish craft breweries falling foul of geographical protection law, begging to get permission to brew seasonal kölsch in Dublin. The tiny glasses it is served in in Cologne, carried around in purpose made trugs by slightly strange waiters who take their responsibility very seriously indeed all add to the intrigue.
