In Germany it's definately beer. I even daresay that we consume more beer than you guys in Belgium, Mrious (I'm not sure if that's something to be proud of, though...).
We have over 5000 beer brands, over 1,200 breweries, and consume an average of 130 litres each year (110 million hectolitres in total) and lots of websites dedicated to beer (otherwise I couldn't have told those numbers).
Personally, I prefer cocktails, though.
