Booze manufactured by old revolutionaries (7)
I believe the answer is:
madeira
'booze' is the definition.
(I know that Madeira is a type of fortified wine)
'manufactured by old revolutionaries' is the wordplay.
'manufactured' becomes 'made' (I've seen this before).
'by old revolutionaries' becomes 'ira' (I can't justify this - if you can you should give a lot more credence to this answer).
'made'+'ira'='MADEIRA'
Can you help me to learn more?
(Other definitions for madeira that I've seen before include "Fortified Portuguese wine" , "Atlantic island, famed for its sweet wine" , "Islands in the Stream?" , "Rich, fortified white wine" , "Island in the Atlantic Ocean" .)
