Study Links White Tea Taste Differences to Amino Acids
A study of three white teas found tea from one wild type more bitter, tea from another sweeter, and Fuding Da Bai richer in umami, and linked the differences to metabolite composition, especially amino acid metabolism.
A study of three white teas finds that teas from two wild tea types differ in taste from Fuding Da Bai, and ties the differences to amino acids.
Xingyun Zhao and ten co-authors in China and Thailand published the work online on 23 September 2026 in the Journal of the Science of Food and Agriculture, ahead of print.
One tea came from a wild "super-large-leaf" type, one from a wild small-leaf type, and one from the cultivated cultivar Fuding Da Bai.
A sensory assessment found significant differences among the teas (P < 0.05). The large-leaf wild tea was more bitter and more astringent, the small-leaf wild tea was sweeter, and Fuding Da Bai showed more umami and mellowness.
Fuding Da Bai held more umami-related amino acids, the large-leaf wild tea more bitter amino acids, and the small-leaf wild tea more sweet-tasting amino acids.
The authors conclude that the taste differences between wild and cultivated white teas are closely linked to metabolite composition, especially amino acid metabolism.
