The US-American chemist Professor Emeritus Ann C. Noble (*1935) studied food science at the University of Massachusetts in Amherst. In 1974, she became the first woman to work in the Department of Viticulture at the University of California in Davis and was assigned to the research project on sensory perception. After studying the technology and handling of wine tastings, she noticed that there is no generally valid and objective terminology regarding the description of wines(wine address) with regard to the different aromatic substances or odours in wine. From 1984 onwards she developed the so-called aroma wheel (aroma wheel, also called aroma circle). This wheel divides the various aromas into 12 main groups, each with several individual aromas. A separate aroma wheel was created for sparkling wine. Since her retirement, she has been a jury member at the San Francisco Chronicle Wine Competition since 2002.
