Whiskey wanted back that is in inaccessible place (5)
I believe the answer is:
eyrie
'inaccessible place' is the definition.
(eyrie can mean a difficult to access place)
'whiskey wanted back that is' is the wordplay.
'whiskey' becomes 'rye whiskey' (rye whiskey is a type of whiskey).
'wanted back' says the letters should be written in reverse.
'that is' becomes 'ie' (short for Latin 'id est', 'that is').
'rye' backwards is 'eyr'.
'eyr'+'ie'='EYRIE'
'in' is the link.
(Other definitions for eyrie that I've seen before include "Large nest of a bird of prey" , "An eagle's nest (5)" , "elevated stronghold" , "highly placed house" , "nest site" .)
