Produce beer, perhaps, for the trading centre (5)
I believe the answer is:
breed
'produce' is the definition.
(breeding is a kind of producing)
'beer perhaps for the trading centre' is the wordplay.
'perhaps' indicates an anagram.
'for' means one lot of letters go next to another.
'centre' says to take the centre.
The middle of 'trading' is 'd'.
'beer' is an anagram of 'bree'.
'bree'+'d'='BREED'
(Other definitions for breed that I've seen before include "Livestock classification" , "Rear; variety" , "Generate" , "Mate and have offspring" , "Produce children" .)
