Obtain and taste bitter (6)
I believe the answer is:
wintry
'bitter' is the definition.
(thesaurus)
'obtain and taste' is the wordplay.
'obtain' becomes 'win' (win can mean to obtain or secure).
'and' is a charade indicator (letters next to each other).
'taste' becomes 'try' (try can mean to taste some food).
'win'+'try'='WINTRY'
(Other definitions for wintry that I've seen before include "Glacial" , "Seasonally cold" , "possibly cold and hostile" , "producing no cheer" , "Cold, bleak" .)
