Heads of vineyard outlets don't keep any spirit (5)
I believe the answer is:
vodka
'spirit' is the definition.
(I've seen this before)
'heads of vineyard outlets don't keep any' is the wordplay.
'heads of' indicates taking the first letters.
The first letters of 'vineyard outlets dont keep any' is 'VODKA'.
(Other definitions for vodka that I've seen before include "Distilled spirit" , "Russian alcoholic drink" , "Alcoholic spirit of Russian origin" , "Colourless alcoholic spirit associated with Russia" , "Russian liquor" .)
