As a Chemist turned Wine Enthusiast, I compleltely appreciates this Podcast, especially the last few minutes when Dr Waterhouse discusses the wine world’s use of chemistry language! Sommeliers and folks in the wine biz use chemistry terms in ways that drive me a little insane. Take the word, aromatic. To a chemist, the word has a completely different meaning than in the wine world. During my first official wine course, I couldn’t fathom what my instructor meant by certain grapes are more aromatic than others... I kept thinking Riesling and Torrontes had more ring-type structures such as benzene. After awhile I’ve grown to accept the wine world’s alternate use of “our” chemistry vernacular.
