Good old man receiving censure for spirit, ... (6)
I believe the answer is:
Here is my best explanation:
'spirit' is the definition.
(I've seen this before)
'good old man receiving censure' is the subsidiary indication.
'good' becomes 'g' (abbreviation).
'old man' becomes 'pa' ('pa' can be a synonym of 'old man'**).
'receiving' is an insertion indicator.
'censure' becomes 'rap' (I've seen this before).
'gpa' enclosing 'rap' is 'grappa'.
'for' is the link.
(Other definitions for grappa that I've seen before include "hard stuff", "form", "Form of brandy", "Distilled spirit", "Italian liqueur made from residue of grapes after pressing", "Brandy made from wine press residue", "Type of brandy", "Italian drink", "Spirit distilled from grapes" and "Italian firewater".)
