CTC black tea, known for its brisk flavor and strong color, is a popular choice among tea lovers worldwide. As a CTC black tea supplier, I am excited to share with you the intricate process of how this remarkable tea is made.
1. Tea Plant Selection and Harvesting
The journey of CTC black tea begins with the careful selection of tea plants. The most common tea plant used for CTC black tea is Camellia sinensis. These plants are typically grown in regions with specific climatic conditions, such as Assam in India, Kenya, and Sri Lanka. The unique combination of soil, altitude, and climate in these areas imparts distinct flavors and characteristics to the tea.
Harvesting is a crucial step in the tea - making process. The tea leaves are usually hand - plucked or machine - harvested. Hand - plucking is a more labor - intensive method but allows for the selection of only the finest leaves. Typically, the top two leaves and a bud are harvested, as these parts of the plant contain the highest concentration of flavor compounds. Machine - harvesting, on the other hand, is more efficient for large - scale production. It can cover a large area in a short time, but it may also include some less - desirable leaves.
2. Withering
Once the tea leaves are harvested, they are spread out in a withering trough or a withering machine. The withering process is essential as it reduces the moisture content of the leaves from about 75 - 80% to around 60 - 65%. This makes the leaves more pliable and easier to process.
During withering, the leaves are exposed to air, and natural enzymes within the leaves start to break down some of the complex compounds. This initial enzymatic activity begins to develop the flavor and aroma of the tea. The withering process usually takes about 12 - 18 hours, depending on the environmental conditions such as temperature and humidity.
3. CTC Process
The "CTC" in CTC black tea stands for "Crush, Tear, Curl." This is the defining step that sets CTC black tea apart from other types of black tea. After withering, the leaves are fed into a CTC machine.
The CTC machine consists of a series of rotating rollers with sharp teeth. As the leaves pass through these rollers, they are crushed, torn, and curled into small, pellet - like particles. This process breaks down the cell walls of the leaves, releasing the tea's essential oils and flavor compounds more quickly. The CTC process results in a more consistent and uniform product, which is ideal for large - scale production and tea bag manufacturing.
4. Fermentation
Fermentation is a critical stage in the production of CTC black tea. After the CTC process, the crushed leaves are spread out on fermentation trays in a controlled environment. The temperature and humidity are carefully regulated to promote the growth of natural enzymes.
During fermentation, the tea leaves undergo a series of chemical reactions. The polyphenols in the leaves are oxidized, which gives the tea its characteristic black color and rich flavor. The fermentation process usually lasts for about 2 - 3 hours, and it is closely monitored to ensure the desired flavor profile is achieved. The aroma of the tea changes significantly during fermentation, developing a complex and robust scent.
5. Drying
Once fermentation is complete, the tea leaves are dried to halt the enzymatic activity and reduce the moisture content to around 3 - 4%. This helps to preserve the tea and prevent spoilage.
The drying process is typically carried out in a hot - air dryer. The tea leaves are passed through a series of chambers where hot air is blown over them. The temperature and airflow are carefully controlled to ensure that the tea is dried evenly. Drying not only stops the fermentation process but also enhances the flavor and aroma of the tea by concentrating the flavor compounds.
6. Sorting and Grading
After drying, the CTC black tea is sorted and graded based on the size and quality of the tea particles. Different grades of CTC black tea have different flavor profiles and uses.
Some of the common grades of CTC black tea include:
- Broken Orange Pekoe Black Tea BOP: This grade consists of medium - sized tea particles. It has a strong, brisk flavor and is often used in blends.
- Broken Pekoe First Grade Black Tea BP1: BP1 is a high - quality grade with larger tea particles. It has a more complex flavor and is suitable for both loose - leaf tea and tea bags.
- Broken Pekoe CTC Black Tea: This grade is known for its strong, full - bodied flavor. It is commonly used in the production of tea blends and instant tea.
7. Packaging
Once the tea is sorted and graded, it is ready for packaging. CTC black tea is typically packaged in tea bags, loose - leaf containers, or bulk bags. The packaging is designed to protect the tea from moisture, light, and air, which can degrade the quality of the tea over time.
For tea bags, the tea is carefully measured and sealed in individual bags. Loose - leaf tea is usually packed in airtight containers, such as tins or foil bags. Bulk tea is often packaged in large sacks or drums for commercial use.
