Bounder spilling first drink (4)

I believe the answer is:

wine

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

'drink' is the definition.
(wine is an alcoholic drink)

I cannot understand how the rest of the clue works.

(Other definitions for wine that I've seen before include "Red, white or rose?" , "tipple" , "Eg, Sauternes" , "eg Claret" , "Colour" .)

I've seen this clue in The Guardian.
