Dram in glass (7)
I believe the answer is:
snifter
I believe this is a double definition.
'dram' is the first definition.
(I've seen this before)
'glass' is the second definition.
(snifter is a kind of glass)
'in' is the link.
(Other definitions for snifter that I've seen before include "A wee dram" , "Catcall" , "brandy glass" , "Small alcoholic drink (colloq.)" , "14 [NIP]" .)
