How does the degree of tea oxidation shape flavor? An analysis of the processing differences between semi-fermented oolong and fully fermented black tea

Rolling and oxidation are the two key stages that determine the direction of a tea's flavor. Rolling shapes the leaf while also influencing the strength and speed of flavor release; oxidation—a process often mislabeled "fermentation"—is in reality merely a reaction between polyphenols and oxygen, yet it directly determines the vast differences in aroma, color, and mouthfeel among oolong, black tea, and even CTC tea. From the distinctive red edge on an oolong leaf, to the apricot-like richness of Chinese black tea, to the strong, lively character of traditional British tea and CTC tea, the degree, speed, and manner of oxidation are the core code that shapes the personality of every cup. This article takes you deeper into how rolling and oxidation affect tea flavor. [more…]

Which tea family does Pu-erh tea belong to? Is Pu-erh considered black tea or dark tea? With detailed brewing temperature and time

Which tea family does Pu'er actually belong to? Is it black tea or dark tea? This question often sparks curiosity among coffee lovers too.
