Author of The Forgotten Sense, a fascinating book about smell, Jonas Olofsson is an olfactory scientist and a professor of psychology at the University of Stockholm. Our in-depth chat covered everything from retronasal olfaction to amoebas, scent marketing to human pheromones, anosmia to sour herring. Listening to Professor Olofsson will change the way you think about the most primal but least understood of our five senses. To read more about Jonas have a look at the Unversity of Stockholm's website. Don’t forget, Cork Talk is now available on Spotify as well as Apple Podcasts, where you can listen to this week’s episode, plus my back catalogue of interviews with some of the world’s most extraordinary wine figures.
