Key Facts
Overview
About Golden-Flower Dark Tea
Golden-flower dark tea is defined by fermentation with the fungus Eurotium cristatum, which forms the golden spots that give the tea its name. Fermentation produces theabrownin, a polymer that is the subject of active research in tea chemistry and metabolic science. Tianyi turns this tea into a standardized instant extract for beverage and wellness-tea products.
