Preprandial tipple (8)
I believe the answer is:
aperitif
'preprandial tipple' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for aperitif that I've seen before include "An alcoholic drink before dinner, an appetiser" , "If pirate may have a drink before dinner?" , "Preprandial drink" , "wine, possibly, before meal" , "Preliminary drink" .)
