Inferior hellholes serve bottles (6)
I believe the answer is:
lesser
'inferior' is the definition.
(I've seen this before)
'hellholes serve bottles' is the wordplay.
'bottles' says the answer is hidden in the clue (bottling is a kind of containing).
'LESSER' is hidden in the letters of 'hellholes serve'.
(Other definitions for lesser that I've seen before include "Not so important (one)" , "Not as great" , "Smaller; inferior" , "That which is smaller, as of two evils" , "Smaller, minor" .)
