Black tea is fully fermented tea leaves. During the fermentation process, the tea tannins oxidize to form tannin red, which not only darkens the tea leaves and gives the infusion a bright red hue but also alters the tea's aroma and flavor, resulting in a fruity fragrance and mellow taste, distinctly different from green tea.
