Coffee shows an appealing bitterness when properly roasted and prepared. But how do the compounds that make coffee taste bitter develop during roasting and how do you analyze and identify them? What lessons can be learned from academic research on coffee roasting to make coffee even more pleasantly bitter-tasting? And after a century of intensive research, why does research still not know exactly what makes coffee bitter at all?
Learn more as Dr. Sara Marquart, curator of the “Cosmos Coffee” exhibition at the Deutsches Museum, shares excerpts of her academic research into bitterness during her Ph.D. at TU Munich in Food Chemistry focused on the highly sophisticated elucidation of reaction pathways and kinetics leading to bitter tastants in roasted coffee.
Also, I will jump in occasionally to help you follow along.
