Red wines turn scarlet (7)

I believe the answer is:

clarets

'red wines' is the definition.
(claret is a kind of red wine)

'turn scarlet' is the wordplay.
'turn' indicates an anagram.
'scarlet' with letters rearranged gives 'CLARETS'.

(Another definition for clarets that I've seen is " Wines that are dark red".)

I've seen this clue in The Globe and Mail.
