How green tea is processed

The processing of green tea is an important factor in determining the flavor and quality of the final product. Green tea is made from the leaves of the Camellia sinensis plant, and the processing method can vary depending on the specific type of tea and the region in which it is grown. Here is a general overview of the processing of green tea:

• Harvesting: Green tea is harvested throughout the year, and the leaves are typically picked by hand. The leaves are usually picked from the top of the plant, as they are the youngest and most tender.
• Withering: After harvesting, the leaves are allowed to wither, or dry out, for a period of time. This process reduces the moisture content of the leaves and makes them more pliable.
• Rolling: After withering, the leaves are rolled or shaped into their final form. This process helps to release the flavor and aroma of the leaves.
• Oxidation: Green tea is not allowed to oxidize, or turn brown, like black tea. To prevent oxidation, the leaves are heated or steamed after rolling. This process stops the enzymatic reactions that cause oxidation and preserves the green color of the leaves.
• Drying: After heating or steaming, the leaves are dried to remove any remaining moisture.
• Sorting: After drying, the leaves are sorted by size and quality.
• Packaging: The final step in the processing of green tea is packaging. Green tea is typically packaged in airtight containers to protect it from moisture and other contaminants.

How green tea is graded
