#79 | Genetic Improvements of Cup Quality: Latest Developments | Hanna Neuschwander, Expo Lectures 2019

World Coffee Research is working to improve the genetic potential of coffee cup quality. To start this task, you first need to define the meaning of “quality.” WCR believes it is a market-driven definition and organized new protocols to assess quality from the perspective of the coffee industry. With experts and partners, WCR produced the coffee lexicon that allows an objective analytic description of coffee quality attributes. In their presentation, Hanna Neuschwander discussed these innovations and shared some lessons learned, including the latest results deriving from these methods and advances on the molecular basis of cup quality. In particular, Hanna highlights the burgeoning importance of some specific volatile compounds like Limonene. These results are not an end but a beginning; an opportunity for further studies to find out the molecular markers or genes related to cup quality in general.

Hanna Neuschwander is the communications director for World Coffee Research, a research nonprofit that works to secure the future of coffee. She writes and speaks globally about coffee science and agriculture. Her writing and commentary has appeared in the Art of Eating, Time Magazine, CNN, BCC, Portland Monthly, and many others. She is the author of Left Coast Roast, a guidebook to coffee roasters on the west coast.
