Coffee or tea option (5)
I believe the answer is:
decaf
This clue is a double definition.
'coffee' is the first definition.
(type of coffee)
'tea option' is the second definition.
(I've seen this in another clue)
(Other definitions for decaf that I've seen before include "Cup substitute missing kick" , "Non-alcoholic drink" , "Type of coffee" , "Style of coffee" , "Less stimulating coffee?" .)
