I believe the answer is:

green tea

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

'drink' is the definition.
(I've seen this before)

I don't understand how the remainder of the clue works.

(Other definitions for green tea that I've seen before include "Food at the golf club" , "Drink - generate (anag)" , "Brewed" , "Beverage" , "Hot drink - teenager (anag)" .)

I've seen this clue in The Guardian.
