Black and green tea come from the same plant but differ in processing methods post-harvest.
Black tea and green tea both come from the same plant species, Camellia sinensis. The main difference between the two lies in the processing methods they undergo after harvesting. Green tea leaves are not oxidized, as they are either steamed or pan-fried, whereas black tea leaves undergo extensive oxidation (also known as fermentation), which gives black tea its characteristic flavor and color.
