Oktoberfest order (4)
I believe the answer is:
bier
'oktoberfest order' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for bier that I've seen before include "Litter" , "German ale" , "Frame for carrying the dead" , "One supports stiff" , "stiff drink in Munich festival" .)
