Very edgy about whiskey (3)
I believe the answer is:
rye
'whiskey' is the definition.
(rye whiskey is a type of whiskey)
'very edgy about' is the wordplay.
'about' says the answer is hidden in the clue (the clue goes around or about the answer).
'RYE' is hidden within 'very edgy'.
(Other definitions for rye that I've seen before include "Whiskey ingredient" , "Cereal used for making whiskey" , "Hard liquor" , "Grain crop" , "Cereal grass - Sussex Cinque Port" .)
