Fermentation Vs. Oxidation This term explains the most common form of preparation for tea leaves, and is correct in most cases. Once a tea leaf has been plucked, it begins to wither and become oxidized. Certain enzymes in the cells of the leaves react to the oxygen in the air. This breaks down chlorophyll in the leaves, causing them to darken and changing their shape and flavor. Heating the leaves can interrupt the process, allowing tea growers to control how much oxidation the leaves experience. The amount of oxidation is one of the primary factors that determines what type of tea is made with the leaves.

Which Decaffeinated Tea Type Contains the Least Amount of Caffeine? In the fifth cup add the same amount of Gunpowder tea pellets. This tea is the control. Bring distilled water placed in a teapot to a rolling boil and pour it over the teas. Allow the teas to steep for 30 seconds to one minute. This will remove most of any caffeine if any is present. The longer the tea is brewed, the more caffeine will be removed but so will other compounds in the tea leaves.

Oolong Tea Oolong tea is made from leaves of the same plant that green and black teas come from. The difference lies in how long the leaves ferment. Green tea leaves are unfermented, while leaves for black tea are fully fermented. Oolong comes from leaves that are partially fermented. Fermentation, or its lack, gives teas their color and aroma. It also alters tea's chemical makeup. The most notable changes happen in a group of chemicals called catechins.

Types of Tea What makes each tea different is the way it has been processed. Tea can be placed into 6 groups based on the amount of processing that goes into the final product. Black Tea This tea goes through the most processing. Once the leaves are picked they are left out in the sun to become slightly wilted. The leaves are then rolled to break open their tissue. The inner chemicals react with the air and begin to ferment. During the fermentation, the leaves darken and change from green to red and finally to black.
