Alcoholic concoction makes you go mad (4)

Ross

I believe the answer is:

I believe this is a double definition.

'alcoholic concoction' is the first definition.
(type of alcoholic drink)

'go mad' is the second definition.
(to flip is to become very angry suddenly)

'makes you' is the link.

(Other definitions for flip that I've seen before include "demanding > alcoholic drink", "hit the roof", "B-side", "Turn over; over-smart", "Turn (over) - impudent".)
