Left some wine (4)
I believe the answer is:
I believe this clue is a double definition.
'left' is the first definition.
(left side of a ship - opposite of starboard)
'some wine' is the second definition.
(port wine is a kind of wine)
(Other definitions for port that I've seen before include "Isle in Dorset" , "Harbour; drink; opening" , "where one would expect water" , "Sweet dark red fortified wine taken after meal" , "Rio, perhaps" .)
