Generate fantastic drink (5,3)

I believe the answer is:

green tea

'drink' is the definition.
(type of tea)

'generate fantastic' is the wordplay.
'fantastic' indicates anagramming the letters.
'generate' is an anagram of 'GREEN TEA'.

(Other definitions for green tea that I've seen before include "Infused drink" , "Colourful drink for teenager" , "brew-up?" , "'Asian herbal drink (5,3)'" , "Infusion" .)

I've seen this clue in The Sun.
