Wine produced by Irish militants (7)
I believe the answer is:
madeira
'wine' is the definition.
(Madeira is an example)
'produced by irish militants' is the wordplay.
'produced' becomes 'made' ('make' can be a synonym of 'produce').
'by irish militants' becomes 'ira' (I can't justify this - if you can you should believe this answer much more).
'made'+'ira'='MADEIRA'
Can you help me to learn more?
(Other definitions for madeira that I've seen before include "Fortified white wine from island off NW Africa" , "Cake - wine" , "Islands in the Stream?" , "Portuguese North Atlantic island" , "A fortified wine, a rich sponge" .)
