If wine leaves a bitter, cotton-like coating on the tongue, neither the sense of taste nor the sense of smell is responsible. The traditional oak barrel character, also called barrique character, is perceived via the trigeminal nerve, which is responsible for, among other things, pain and temperature perception. This is reported in the journal "Chemical Senses" by a research team headed by Prof Dr Dr Dr Hanns Hatt from the Faculty of Biology and Biotechnology at the Ruhr-Universität.
