Black tea is a type of tea made from the leaves of Camellia sinensis, the same plant that makes green tea and oolong tea. The main difference between these teas is the processing. Black tea is typically made by fully oxidizing the leaves, which gives it its characteristic pale black color and rich flavor.
1. Black Tea Processing
The process of making black tea involves the following main steps:
– Harvesting: Camellia sinensis leaves are harvested by hand or by machine in tea farms.
– Softening: The tea leaves are placed over fire to remove moisture and soften them.
– Rolling: The tea leaves are rolled to break down the cells and stimulate oxidation.
– Oxidation: The tea leaves are then completely oxidized by exposing them to air. This process produces a pale black color and creates flavor compounds.
– Drying: Finally, the tea leaves are dried to prevent oxidation and ensure the quality of the final product.

Therefore, you should inform your doctor if you are drinking a lot of black tea or taking any supplements.
