Nazis drinking house wines as affectation (9)

I believe the answer is:

showiness

'affectation' is the definition.
(thesaurus)

'nazis drinking house wines' is the wordplay.
'nazis' becomes 'SS' (the SS was a Nazi organisation).
'drinking' is an insertion indicator (inserted letters are consumed or drunk).
'house' becomes 'ho' (abbreviation for house).
'ho'+'wines'='howines'
'ss' enclosing 'howines' is 'SHOWINESS'.

'as' is the link.

I've seen this clue in The Independent.
