Fenghuang Dancong tea (FHDC) is a renowned oolong tea in China due to its complex aroma characteristics. However, the aroma differences between FHDC teas with typical aroma profiles are still unknown. This study employed the sensomics approach to characterize the key odorants in three distinct FHDC samples with aroma types of Yashi, Huangzhi, and Milan, respectively.
