In this lecture Jancis explains the importance of smell and how your olfactory bulb can tell you more about wine than any other part of your body. She discusses the importance of aroma and how to spot a corked or oxidised wine. She explains how wine tasters describe the smell of wine through similes comparing wine to fruit, vegetables, spices, minerals and other scents we experience in everyday life. She mentions how different wine tasters use their own vocabularies, and how newcomers can be as descriptive as more experienced wine tasters.
