Yes, I know (now). But we don't have this measurement of a "standard drink" at all. An Australian ex-coworker had to explain the term, much to my confusion. By "the standard" I simply meant what you will get if you go to a restaurant (or pub or bar) and order "one beer".
Seems that most beers in Bavaria probably approximately equate to 2 standard drinks, meanwhile a small Pilsener commonly found in the North is about 1 standard drink.
