Left some alcohol (4)
I believe the answer is:
port
I believe this is a double definition.
'left' is the first definition.
(left side of a ship - opposite of starboard)
'some alcohol' is the second definition.
(port is a type of wine)
(Other definitions for port that I've seen before include "Popular after dinner liqueur" , "Saint John, for one, > left" , "Left side of ship - red wine" , "Drink passed to the left" , "Anchorage" .)
