Wrong option for a drink (6)

I believe the answer is:

potion

'for a drink' is the definition.
(potion is a kind of drink)

'wrong option' is the wordplay.
'wrong' indicates an anagram.
'option' with letters rearranged gives 'POTION'.

(Other definitions for potion that I've seen before include "Medicinal or magical beverage" , "Witches' brew" , "Magical liquid" , "Option of a liquid medicine" , "curative drink" .)

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