I can at least make a small contribution to the caffeine content. This is actually due to the German limit values. If you buy the RB in Austria, it has considerably more caffeine.
@Multibagger I thought so. Personally, the "small portion" in German drinks is enough for me, but I'm still annoyed by this culture of regulations and paternalism that, for example, films or video games are cut especially for the German market.
