Delicious beverage reportedly downed with pirate’s approval? (6)
I believe the answer is:
nectar
'delicious beverage' is the definition.
(drink of the gods in classical mythology)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for nectar that I've seen before include "Sweet fluid collected by bees" , "Divine beverage" , "Sweet, delicious, drink" , "very nice drink" , "Food of gods" .)
