I believe the answer is:

nectar

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

'sweet drink' is the definition.
(I've seen this in another clue)

'bureaucrat censures members knocking back' is the wordplay.
'NECTAR' is hidden back-to-front within the letters.
However, I'm uncertain how the hidden word is indicated.

Can you help me to learn more?

(Other definitions for nectar that I've seen before include "Sweet liquid secretion to attract pollinators" , "Sweet floral secretion" , "Trance (anag)" , "Secretion collected by bees" , "Recant (anag.)" .)

I've seen this clue in The Irish Times.
