Sicilian dessert wine (7)
I believe the answer is:
marsala
'sicilian dessert wine' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for marsala that I've seen before include "Alcoholic drink" , "Fortified Sicilian wine" , "Sicilian dessert wine" , "Wine - as alarm (anag)" , "Dessert wine from Sicily" .)
