Coffee purist footing delicate brews (4,5)
I believe the answer is:
'footing delicate brews' is the definition.
I know nothing about this answer so I cannot judge whether this works.
'coffee purist' is the wordplay.
'coffee' becomes 'iced coffee' (iced coffee is a kind of coffee).
'purist' becomes 'latte' (I can't explain this - if you can you should give a lot more credence to this answer).
Can you help me to learn more?
