This is the same amount of racist as depicting a German wearing lederhosen and holding a mug of beer.

Which is to say, not very much. Harmless and inoffensive stereotypes.

In fact, Germans probably drink beer less often than Chinese eat with chopsticks, because they literally use them for every meal, even breakfast. However, they wear those silly hats and clothes about as much as Germans wear lederhosen, which is like once a year, for Oktoberfest.
