Second brew — fine coffee (5)
I believe the answer is:
mocha
'fine coffee' is the definition.
(I've seen this before)
'second brew' is the wordplay.
'second' becomes 'mo' (both are short periods of time).
'brew' becomes 'cha' (I've seen this in other clues).
'mo'+'cha'='MOCHA'
(Other definitions for mocha that I've seen before include "Coffee drink" , "Dark brown" , "Kind of coffee" , "Fine-quality coffee" , "Yemeni port; type of coffee bean" .)
