Mythological Greek god of wine and fertility (8)
I believe the answer is:
dionysus
(Other definitions for dionysus that I've seen before include "Greek god of wine and creativity" , "Greek god of wine and good times" , "Greek god (Bacchus is his Roman equivalent)" , "Greek god of wine and fertility, also known as Bacchus" , "Sins you'd associate with Greek god of wine and fertility" .)
