The word is "head" in English
and it doesn't matter how much "head" you have, when it finally disappears it doesn't make any difference (maybe a fraction of a milliimetre) to the beer level because it is froth, mainly bubbles. So the idea that the difference in level is due to the head is ridiculous.
I have nothing againsy Germany or Germans, I drive a german car for gods sake, the best car I ever had was a BMW. Germany has a much better record than we do at international football - no problem. Just be objective please.
I'm even prepared to admit that German head is better than ours, specially when given by Angela Merkhal.
