Zinfandel or merlot
I believe the answer is:
wine
'zinfandel or merlot' is the definition.
(I know that Zinfandel is a grape variety)
This is all the clue.
(Other definitions for wine that I've seen before include "Accompaniment for women and song?" , "Alcoholic grape juice" , "Plonk" , "Drink made from grapes" , "Chianti or Chardonnay?" .)
