But you do realize "5" isn't the same as 5 bottle/cans here in the States...........
Yes I do realize, here in Munich, if we are talking about "5" that is
5 liters, the alkohol contents about 6.5 to 9.0 vol percent, depending on brand. How strong is yours in the USofA?
If you are not used to drinking beer at the Oktoberfest, you will most probably have to be carried out after 3 liters.
So my advice: before coming over to Germany, do some training - and BTW you do not need a "Brown Bag" over here.
