Type of white wine (8)
I believe the answer is:
riesling
'type of white wine' is the definition.
This is all the clue.
(Other definitions for riesling that I've seen before include "Aromatic white wine from the Rhine valley" , "Fragrant white wine from the Rhine valley or from California" , "Sir Ingle makes wine from this grape" , "Strange wine for Sir Ingle" , "Dry white wine (German)" .)
