Greek god of wine (7)
I believe the answer is:
bacchus
'greek god of wine' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for bacchus that I've seen before include "Roman god of wine and revelry" , "Divinity" , "Greek god of drink, also called Dionysus" , "Roman god of drink and revelry" , "Another name for Dionysus, Greek god of drink" .)
