Beer making you resentful (6)
I believe the answer is:
bitter
I believe this is a double definition.
'beer' is the first definition.
(bitter is a type of beer)
'resentful' is the second definition.
(synonyms)
'making you' is the link.
(Other definitions for bitter that I've seen before include "Sour tasting, like English ale" , "Tart or resentful" , "Type of beer" , "Sarcastic (words); very cold" , "Act nervously" .)
