Black tea and green tea are two types of infusions that are obtained from the same plant, Camellia sinensis. The difference between the two lies in the degree of oxidation that the leaves suffer during processing. Black tea is the most oxidized, giving it a darker color and more intense flavor. Green tea undergoes a heat treatment that prevents oxidation, preserving its green color and milder flavor.

Black tea and green tea have different uses and customs depending on the culture and region where they are consumed.
