Admire a complex wine (7)
I believe the answer is:
madeira
'wine' is the definition.
(I know that Madeira is a type of fortified wine)
'admire a complex' is the wordplay.
'complex' indicates an anagram.
'admire'+'a'='admirea'
'admirea' anagrammed gives 'MADEIRA'.
(Other definitions for madeira that I've seen before include "Sponge-cake" , "Dessert wine from a Portuguese Atlantic island" , "Portuguese North Atlantic island" , "Atlantic territory" , "Portuguese island, capital Funchal" .)
