Very excited about whiskey (3)
I believe the answer is:
rye
'whiskey' is the definition.
(rye whiskey is a type of whiskey)
'very excited about' is the wordplay.
'about' indicates the answer is hidden within the clue (the clue goes around or about the answer).
'RYE' is hidden in the letters of 'very excited'.
(Other definitions for rye that I've seen before include "Whisky; Sussex town" , "A Cinque Port; a grain" , "Cereal grass - Sussex Cinque Port" , "Grass - whiskey" , "Type of whisky" .)
