King's taps possibly producing a cold beverage and two vitamins (8)
I believe the answer is:
accolade
'king's taps possibly' is the definition.
I can't tell whether this defines the answer.
'a cold beverage and two vitamins' is the wordplay.
'two vitamins' can mean two substitutions for 'vitamin'.
'cold' becomes 'C' (eg on taps).
'beverage' becomes 'cola' (cola is a kind of beverage).
'and' is a charade indicator (letters next to each other).
'vitamin' becomes 'D' (D is an example).
'vitamin' becomes 'E' (E is an example).
'a'+'c'+'cola'+'d'+'e'='ACCOLADE'
'producing' is the link.
Can you help me to learn more?
(Other definitions for accolade that I've seen before include "Praise, or touch on shoulder to confer knighthood" , "Praise or approval - or elevation to knighthood" , "Public praise or award" , "Tribute expressing great approval" , "Special honour as an acknowledgment of merit" .)
