Description
Fei Yan, Xiaohua Chen, Dong Qu, and a wider team wrote this research paper, published in 2024. It shows how to tell where a congou black tea from southern Shaanxi was grown, by combining human tasting with a chemical fingerprint of its aroma.
Teas from the region vary in quality with altitude and craft, and false origin labels cost honest producers money. The team measured sixty-one volatile compounds with a gas separation and ion mobility instrument. Tasters sorted the teas into three aroma families. Teas from mid-altitude areas smelled green and roasted, with six marker compounds. Teas from higher areas smelled of honey and caramel, carried by three other markers. Aroma type, chemistry, and origin lined up clearly. The authors offer the method as a tool against fraud in a prized tea region.
