Wine greeting worker in Channel Islands (7)
I believe the answer is:
chianti
'wine' is the definition.
(Chianti is an example)
'greeting worker in channel islands' is the wordplay.
'greeting' becomes 'hi' (hi is a kind of greeting).
'worker' becomes 'ant' (worker is a type of ant).
'in' indicates putting letters inside.
'channel islands' becomes 'ci'.
'hi'+'ant'='hiant'
'hiant' going into 'ci' is 'CHIANTI'.
(Other definitions for chianti that I've seen before include "Tuscan red wine" , "Popular dry red wine of Tuscany" , "Italian offering" , "Chain it to popular Italian wine" , "European wine" .)
