Outline
To construct a flavor wheel and systematically characterize the sensory characteristics of Yunnan large-leaf white tea.
Following established international methodologies for flavor wheel development and the national standard GB/T 16861—1997 Sensory analysis-Identification and selection of descriptors for establishing a sensory profile by a multidimensional approach, 22 representative tea samples varying in vintage,origin and cultivar were selected for sensory evaluation. Core sensory descriptors were extracted, screened and refined to develop the Yunnan large-leaf white tea flavor wheel. Furthermore, M and multivariate statistical analysis was employed to identify key differential descriptors.
Finally, a total of 38 descriptive words that represent distinct flavor profiles were determined, comprising 16 aroma terms (e.g., orchid, osmanthus), 7 infusion color terms (e.g., yellowish green, light yellow, deep yellow) and 15 taste/mouthfeel terms (e.g., sweet aftertaste, mellow sweetness, fresh briskness).These descriptors were successfully applied in flavor profiling.
The proposed descriptive system effectively characterizes the flavor profile of Yunnan large-leaf white tea and successfully differentiates samples across categories, validating the scientific robustness of the constructed flavor wheel. This study provides a standardized framework for quality assessment and facilitates communication among producers, consumers and connoisseurs by establishing a shared sensory vocabulary, thereby enhancing the overall appreciation of this tea.
