Pungency of beer associated with head? (10)
I believe the answer is:
bitterness
'pungency' is the definition.
(thesaurus)
'beer associated with head?' is the wordplay.
'beer' becomes 'bitter' (I've seen this before).
'associated with' is a charade indicator (letters next to each other).
'head?' becomes 'ness' (ness is a headland**).
'bitter'+'ness'='BITTERNESS'
'of' is the link.
(Other definitions for bitterness that I've seen before include "Acrimony" , "Unrelenting resentment" , "Sharp taste" , "Acerbity" , "sharp pungent quality" .)
