The Invisible Off-Flavours Ruining Your Beer: Sub-Recognition Thresholds

Have you ever had a beer that was technically clean, but just felt... "wrong"? You couldn't taste cooked corn, diacetyl, or rotten eggs, but something in your brain told you not to order another pint. In this video, we dive into the hidden world of Sub-Recognition Off-Flavours—the sensory danger zone where a flavour compound is strong enough for your brain to detect, but too weak to identify. We explore the fascinating psychology and evolutionary biology behind why our brains treat unidentifiable tastes as literal threats, and how this "cognitive noise" silently ruins brand trust.
