Drink dispenser brewing ice tea, mostly free (9)

I believe the answer is:

cafetiere

I'm a little stuck... Click here to teach me more about this clue!

'drink dispenser' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.

'brewing ice tea mostly free' is the wordplay.
'brewing' is an anagram indicator.
'mostly' means to remove the last letter.
'free' with its last letter removed is 'fre'.
'ice'+'tea'+'fre'='iceteafre'
'iceteafre' anagrammed gives 'CAFETIERE'.

Can you help me to learn more?

(Other definitions for cafetiere that I've seen before include "Coffee pot" , "Drink supplier" , "Jug with filter used to make coffee" , "coffee-maker" .)

I've seen this clue in The Telegraph.
