The methods and techniques involved in the production of tea from leaves of the Camellia sinensis plant.
Tea Processing
Tea processing is the method in which the leaves from the Camellia sinensis plant are transformed into the dried leaves for brewing tea. The categories of tea are distinguished by the processing they undergo. The most common types of tea are green tea, black tea, oolong tea, white tea, and pu-erh tea.
Stages of Tea Processing
The processing of tea involves several key stages, each contributing to the final flavor and characteristics of the tea.
Withering
Withering is the first step in tea processing. Freshly plucked tea leaves are spread out in thin layers to wither, which reduces their moisture content. This process makes the leaves pliable and prepares them for further processing. Withering can be done naturally by air or through controlled environments.
Rolling
After withering, the leaves are rolled to break their cell walls, which releases essential oils and initiates oxidation. Rolling can be done by hand or using machines. The rolling process also shapes the leaves into the desired form.
Oxidation
Oxidation is a crucial step that affects the flavor and color of the tea. During oxidation, the leaves are exposed to air, allowing enzymes to react with oxygen. This process is responsible for the dark color of black tea and the unique flavors of oolong tea. The level of oxidation is controlled to produce different types of tea.
Firing
Firing is the process of drying the leaves to stop oxidation and remove any remaining moisture. This step is essential to preserve the tea and prevent spoilage. Firing can be done using hot air, pan-firing, or baking.
Sorting and Grading
After firing, the tea leaves are sorted and graded based on size and quality. This step ensures uniformity in the final product and helps in marketing the tea.
Types of Tea
Green Tea
Green tea is minimally oxidized, retaining its green color and fresh flavor. The leaves are quickly steamed or pan-fired after withering to prevent oxidation.
Black Tea
Black tea is fully oxidized, resulting in a dark color and robust flavor. It undergoes a longer oxidation process compared to other teas.
Oolong Tea
Oolong tea is partially oxidized, falling between green and black tea in terms of flavor and color. The oxidation level can vary, producing a wide range of flavors.
White Tea
White tea is the least processed, made from young leaves and buds that are simply withered and dried. It has a delicate flavor and light color.
Pu-erh Tea
Pu-erh tea is a fermented tea, undergoing a unique aging process that develops its rich, earthy flavor. It can be aged for several years.
