Fierce tea - wrong pot (9)
I believe the answer is:
cafetiere
'pot' is the definition.
(I've seen this before)
'fierce tea wrong' is the wordplay.
'wrong' is an anagram indicator.
'fierce'+'tea'='fiercetea'
'fiercetea' is an anagram of 'CAFETIERE'.
(Other definitions for cafetiere that I've seen before include "Coffee pot" , "Drink supplier" , "Jug with filter used to make coffee" , "coffee-maker" .)
