Reptile from north into Japanese wine (5)
I believe the answer is:
snake
'reptile' is the definition.
(I know that snake is a type of reptile)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for snake that I've seen before include "Limbless reptile" , "Slithering reptile" , "Entertainer with music and reptiles" , "Carnivorous reptile" , "Serpent" .)
