Plonk an iron drive with mid-air spin (3,9)
I believe the answer is:
vin ordinaire
'plonk' is the definition.
(I've seen this before)
'an iron drive with mid-air spin' is the wordplay.
'with' is a charade indicator (letters next to each other).
'mid' means to look at the middle letters.
'spin' is an anagram indicator.
The centre of 'air' is 'i'.
'an'+'iron'+'drive'+'i'='anirondrivei'
'anirondrivei' is an anagram of 'VIN ORDINAIRE'.
(Other definitions for vin ordinaire that I've seen before include "this isn't the best drink" , "Plonk" , "Cheap table wine" .)
