So, let’s dive in and explore the many benefits of green tea!
What is Green Tea?
Green tea is a type of tea made from the leaves of the Camellia sinensis plant.
The tea leaves are processed in a special way, which prevents them from oxidizing, allowing them to retain their unique flavor and beneficial compounds.
The first step is withering, which involves laying the freshly picked tea leaves out to dry in the sun or in a warm, well-ventilated room. This allows some of the moisture to evaporate and softens the leaves, making them more pliable for the next step.
The second step is fixation, which involves heating the tea leaves to stop the oxidation process. This is typically done by pan-firing the leaves in a large wok or steaming them. Fixation helps preserve the natural green color of the leaves and prevents them from turning brown or black.
The third step is rolling, which involves shaping the tea leaves into thin, twisted strips. This is typically done by hand or with a machine that gently rolls and twists the leaves.
The final step is drying, which involves removing any remaining moisture from the tea leaves. This is typically done by firing them in an oven or a large basket over a charcoal fire. The dried leaves are then sorted and packaged for distribution.
The exact processing methods can vary depending on the type of green tea being produced and the region where it is grown.
