Brandy glass (7)
I believe the answer is:
snifter
'brandy glass' is the definition.
(I know that brandy glass can be written as snifter)
This is all the clue.
(Other definitions for snifter that I've seen before include "Small quantity of alcoholic drink" , "Catcall" , "A wee dram" , "Strong breeze - strong drink" , "14 [NIP]" .)
