Make the young drink (6)
I believe the answer is:
brandy
'drink' is the definition.
(brandy is a kind of drink)
'make the young' is the wordplay.
'make' becomes 'brand' ('brand' can be a synonym of 'make').
'the young' becomes 'y'.
'brand'+'y'='BRANDY'
(Other definitions for brandy that I've seen before include "- - -snap" , "Eau de vie" , "Reviving alcoholic spirit" , "Strong liquor" , "Utensil or shop" .)
