Must be that Cologne (Koln) - Dusseldorf rivalry. When I was in Dusseldorf, I asked the server for a Kolsch. He laughed and thought I was joking. Apparently it's tantamount to looking for a Mets cap in Yankee stadium.

and others take delight in the hurling and the bowling
but I take delight in the juice of the barley
and courting pretty fair maids in the morning bright and early
