Doctor receiving reprimand, having a brandy (6)
I believe the answer is:
grappa
'brandy' is the definition.
(grappa is a kind of brandy)
'doctor receiving reprimand having a' is the wordplay.
'doctor' becomes 'gp' (general practitioner**).
'receiving' is an insertion indicator.
'reprimand' becomes 'rap' (rap is a kind of reprimand).
'having' says to put letters next to each other.
'gp' enclosing 'rap' is 'grapp'.
'grapp'+'a'='GRAPPA'
(Other definitions for grappa that I've seen before include "Italian firewater" , "Brandy made from wine press residue" , "Italian spirit made from grape residue after pressing" , "Brandy from fermented pressed grape residue" , "Form of brandy" .)
