I'd skip the Heineken and Beck's; they don't seem to survive the trip overseas. In fact, Heineken can only be drunk in the Netherlands. As soon as you cross the border, the quality drop is extraordinary. Of course, when in Holland you're guaranteed more interesting things to drink; so perhaps my assertion should be that you shouldn't bother with Heineken ever. When I'm after a clean German lager, I usually have good luck with Warsteiner.
