Upset, a steward will admit discrimination (5)

I believe the answer is:

taste

'discrimination' is the definition.
(taste is a kind of discrimination)

'upset a steward will admit' is the wordplay.
'will admit' says the answer is hidden in the clue.
'TASTE' can be found hidden inside 'upset a steward'.

(Other definitions for taste that I've seen before include "Test for flavour" , "Show sense" , "A sense; briefly sample" , "Appreciation, discernment" , "Delicacy" .)

I've seen this clue in The Telegraph.
