Beer bottle emptied -- stocks ran low, sadly (5,3)
I believe the answer is:
brown ale
'beer' is the definition.
(I've seen this before)
'bottle emptied stocks ran low sadly' is the wordplay.
'emptied' means to remove the middle letters.
'stocks' is an insertion indicator (stocks can mean carries or contains).
'sadly' is an anagram indicator.
'bottle' with its centre removed is 'be'.
'ran'+'low'='ranlow'
'ranlow' anagrammed gives 'rownal'.
'be' placed around 'rownal' is 'BROWN ALE'.
(Other definitions for brown ale that I've seen before include "bottled beer" , "Dark, mild beer" , "Noble war (anag) - drink" , "Dark, malty beer" , "Type of beer" .)
