Still bitter maybe, writer, after months (7)
I believe the answer is:
alembic
'still' is the definition.
(I know that alembic is a type of still)
'bitter maybe writer after months' is the wordplay.
'bitter maybe' becomes 'ale' (type of beer or bitter. I am not sure about the 'maybe' bit.).
'writer' becomes 'bic' (Bic is a manufacturer of pens).
'after' says to put letters next to each other.
'months' becomes 'm'.
'bic' put after 'm' is 'mbic'.
'ale'+'mbic'='ALEMBIC'
Can you help me to learn more?
(Other definitions for alembic that I've seen before include "Old retort" , "Old distillation vessel" , "Still" .)
