Ordered as whisky may be (4)
I believe the answer is:
neat
This clue is a double definition.
'ordered' is the first definition.
(I've seen this in another clue)
'as whisky may be' is the second definition.
(I've seen this before)
(Other definitions for neat that I've seen before include "efficient" , "Excellent American" , "without ice?" , "without water being added" , "Tidy, well-organised" .)
