Just by shaking the bottle, some people make assumptions if the liquor in there is adulterated or not. I donât know the philosophy behind it, they say that more the bubble retention the better the liquor is supposed to be. Itâs convincing but not convincing enough! Anyway, after two pegs down itâs all fair and square. I donât advise carrying a gadget each time you walk into a pub, for that it will make you suspicious, but you do have a choice.
The Rotgutonix, though still a prototype, is a small handheld device that can detect adulterated alcohol. Presently compatible with only five brands (JB, Johnny Walker, DYC, Habana Club, Brugal and Pampero), it has a display that notifies the user if its 100% the brand or rotgut (adulterated).
