Initially Evening Standard journalists love coffee (8)
I believe the answer is:
espresso
'coffee' is the definition.
(espresso is a kind of coffee)
'initially evening standard journalists love' is the wordplay.
'initially' indicates taking the first letters.
'journalists' becomes 'press' (the press can mean the newspaper industry).
'love' becomes 'o' (love means zero in tennis).
The first letters of 'evening standard' is 'es'.
'es'+'press'+'o'='ESPRESSO'
(Other definitions for espresso that I've seen before include "Coffee made by forcing steam through grounds" , "Kind of shot" , "Italian strong coffee traditionally in a little cup" , "Coffee made under steam pressure" , "Coffee-making machine" .)
