Wine in port I spoiled, certainly not bottled (5,4)
I believe the answer is:
pinot noir
'wine' is the definition.
(Pinot noir is an example)
'in port i spoiled certainly not bottled' is the wordplay.
'spoiled' is an anagram indicator.
'certainly not' becomes 'no'.
'bottled' means one lot of letters goes inside another (to bottle can mean contain).
'in'+'port'+'i'='inporti'
'inporti' anagrammed gives 'pitnoir'.
'pitnoir' placed around 'no' is 'PINOT NOIR'.
(Other definitions for pinot noir that I've seen before include "no white wine" , "Type of red" , "18 [WINE]" , "Fruit" , "Drink" .)
