Not prepared to hear about cold drink (5)

Ross

I believe the answer is:

decaf

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

'drink' is the definition.
(decaffeinated coffee)

'not prepared to hear about cold' is the wordplay.
I cannot really see how this works, but
'about' could be 'ca' (circa) and 'ca' is found within the answer.
The remaining letters 'def' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...

Can you help me to learn more?

(Other definitions for decaf that I've seen before include "Type of coffee" , "Less stimulating coffee?" , "Style of coffee" , "Coffee without the kick?" , "Cup substitute missing kick" .)
