Church unit against wine (7)
I believe the answer is:
chianti
'wine' is the definition.
(Chianti is an example)
'church unit against' is the wordplay.
'church' becomes 'ch' (common abbreviation).
'unit' becomes 'i' ('I' can be a synonym of 'unit').
'against' becomes 'anti' (I've seen this before**).
'ch'+'i'+'anti'='CHIANTI'
(Other definitions for chianti that I've seen before include "Chain it to popular Italian wine" , "I can hit for popular Italian wine" , "Italian wine variety" , "Wine produced in Tuscany" , "Italian wine - mountain range" .)
