Temper from woman with endless beer (6)
I believe the answer is:
anneal
'temper' is the definition.
('anneal' can be a synonym of 'temper')
'woman with endless beer' is the wordplay.
'woman' becomes 'anne' (I've seen this before**).
'with' is a charade indicator (letters next to each other).
'endless' means to remove the last letter.
'beer' becomes 'ale' (I've seen this before).
'ale' with its final letter taken off is 'al'.
'anne'+'al'='ANNEAL'
'from' is the link.
(Other definitions for anneal that I've seen before include "toughening process" , "Soften or toughen" , "Heat-treat (metal or glass)" , "Heat and cool slowly in order to toughen" , "Temper, harden" .)
