Nurses’ tea enlivened by a bottle of this? (9)
I believe the answer is:
sauternes
'a bottle of this?' is the definition.
(wine from the Sauternais region in France)
'nurses' tea enlivened' is the wordplay.
'enlivened' indicates anagramming the letters (letters energised or enlivened into movement).
'nurses'+'tea'='nursestea'
'nursestea' anagrammed gives 'SAUTERNES'.
'by' is the link.
(Other definitions for sauternes that I've seen before include "Sweet white wine" , "A sweet Bordeaux" , "Sweet French wine" .)
