Church worker perhaps taken on by team to provide wine (7)
I believe the answer is:
chianti
'wine' is the definition.
(Chianti is an example)
'church worker perhaps taken on by team' is the wordplay.
'church' becomes 'ch' (abbreviation on maps etc).
'worker perhaps' becomes 'ant' (worker is a type of ant).
'taken on by' means one lot of letters goes inside another (inserted letters get taken on or taken in).
'team' becomes 'ii'.
'ant' put within 'ii' is 'ianti'.
'ch'+'ianti'='CHIANTI'
'to provide' is the link.
(Other definitions for chianti that I've seen before include "European wine" , "Wine produced in Tuscany" , "I can hit for popular Italian wine" , "Italian offering" , "Tuscan red wine" .)
