Rioters rioting about races for coffee (9)

I believe the answer is:

ristretto

'coffee' is the definition.

'rioters rioting about races' is the wordplay.
'rioting' indicates an anagram.
'about' is an insertion indicator.
'races' becomes 'tt' (Isle of Man Tourist Trophy races).
'rioters' with letters rearranged gives 'ristreo'.
'ristreo' placed around 'tt' is 'RISTRETTO'.

'for' is the link.

I've seen this clue in The Telegraph.
