Produce from central Umbria and Oviedo (4)
I believe the answer is:
'produce' is the definition.
'central umbria and oviedo' is the wordplay.
'central' says to take the centre.
'and' means one lot of letters go next to another.
'oviedo' becomes 'ie' (I am not sure about this - if you are sure you should believe this answer much more).
The middle letters of 'umbria' are 'br'.
'from' is the link.
(Other definitions for brie that I've seen before include "Round soft Fr. cheese" , "Bergamot-flavoured tea" , "French produce" , "Variety of cheese" , "Soft and creamy mild white cheese" .)
