Admire a new dessert wine (7)
I believe the answer is:
madeira
'dessert wine' is the definition.
(I've seen this before)
'admire a new' is the wordplay.
'new' is an anagram indicator.
'admire'+'a'='admirea'
'admirea' is an anagram of 'MADEIRA'.
(Other definitions for madeira that I've seen before include "Sponge-cake" , "Atlantic territory" , "Fortified wine from Atlantic island" , "Islands in the Stream?" , "Island in the Atlantic Ocean" .)
