Processing of Tea Leaves: Step-by-Step Guide
Tea is not just a beverage; rather, it is a journey that begins in lush green gardens and ends in your cup. What truly defines the taste, aroma, and colour of tea is the processing of tea leaves. From the moment farmers pluck fresh leaves to the time factories dry and pack them, every step plays a crucial role. By understanding this process, you can better appreciate why one tea tastes bold and brisk while another feels light and floral.
In this article, we will explore the steps of processing tea leaves, explain the process of making tea in a factory, and clearly break down how tea is made and processed in a simple and enjoyable way.
1. Plucking: The First and Most Crucial Step
The journey starts in the tea gardens. Skilled workers carefully pluck tender shoots, usually the top two leaves and a bud. This standard helps maintain consistent quality and flavour. Moreover, timing matters greatly. Farmers transport freshly plucked leaves to the factory as quickly as possible to prevent early oxidation.

2. Withering: Preparing the Leaves for Transformation
Once the leaves reach the factory, workers spread them on long troughs or racks for withering. During this stage, the leaves lose excess moisture and become soft and flexible. At the same time, natural chemical changes begin to shape aroma and strength.
Therefore, factories must control this step carefully. Over-withering dulls flavours, while under-withering makes rolling difficult. As a result, withering quietly sets the foundation for the final taste.
3. Rolling or CTC: Breaking the Leaf Cells
After withering, the leaves move to rolling or crushing. This step breaks the leaf cell walls and releases enzymes that react with oxygen.
Factories generally follow one of two methods in the processing of tea leaves:
- Orthodox method: Workers gently roll the leaves, preserving their shape and complexity. This method often produces premium loose-leaf teas.
- CTC (Crush, Tear, Curl) method: Machines crush the leaves into small granules, creating strong teas that brew quickly and suit teabags.
Because of this choice, the final tea can taste either delicate or bold.
4. Oxidation: Developing Colour and Flavour
Next comes oxidation, a natural enzymatic reaction. After rolling, factories spread the leaves in controlled conditions where oxygen interacts with the leaf compounds.
This stage determines the tea type:
- Minimal oxidation creates green or white tea
- Partial oxidation produces oolong tea
- Full oxidation results in black tea
Since oxidation time directly affects colour and aroma, skilled supervision becomes essential at this stage.
5. Fixation: Stopping Oxidation for Green Teas
When producing green tea, factories stop oxidation early. They apply heat through steaming or pan-frying, which deactivates the enzymes. Consequently, the leaves retain their green colour and fresh, grassy flavour.
Without fixation, green tea would continue oxidising and lose its signature character.
6. Drying: Locking in Quality
After oxidation or fixation, the leaves go through drying. Hot air dryers remove remaining moisture and halt all chemical activity. As a result, the tea becomes shelf-stable while preserving aroma and taste.
By the end of this step, the leaves turn crisp and ready for sorting.
7. Sorting, Grading, and Packing
Finally, workers sort and grade the dried leaves based on size and appearance. In many cases, factories blend teas to achieve a consistent flavour across batches. Then, they pack the finished tea for distribution.
This stage completes the process of making tea in a factory.

Why Processing Matters So Much
Interestingly, the same tea leaf can produce green, oolong, or black tea. The difference lies entirely in how producers handle the leaves after plucking. That is why learning how tea is made and processed adds depth to every cup you drink.

Final Thoughts
The processing of tea leaves combines science, tradition, and human skill. Each step—from plucking to drying—directly shapes the final cup. Therefore, the next time you sip tea, remember that behind its simplicity lies a carefully crafted process refined over generations.
Tea is not just made; it is thoughtfully crafted.
