- Introduction to Orthodox and CTC Black Tea
In the black tea industry, the two most common processing methods are Orthodox and CTC (Crush, Tear, Curl). Both methods produce black tea, but differences in production processes result in distinct flavor profiles and applications. Understanding these differences helps tea businesses choose the right product for their target market.
- Processing Methods
Orthodox Black Tea
The Orthodox method uses traditional techniques, focusing on preserving the natural shape of the tea leaves. The main steps include:
- Withering: Fresh tea leaves are withered to reduce moisture content.
- Rolling: The withered leaves are gently rolled to break the cell structure, releasing enzymes and initiating oxidation.
- Oxidation: The rolled leaves undergo full oxidation, turning dark and developing the classic black tea color.
- Drying: The oxidized leaves are dried to stop oxidation and lock in the flavor.
CTC Black Tea
The CTC method uses modern machinery to produce tea more quickly, creating small, uniform granules. The main steps include:
- Withering: Tea leaves are rapidly withered.
- Crush, Tear, Curl: The leaves pass through CTC machines, where they are crushed, torn, and curled, accelerating oxidation.
- Oxidation: The small leaf particles quickly turn dark brown or black.
- Drying: The oxidized particles are dried to halt oxidation and finalize the product.
- Flavor Comparison
- Orthodox Black Tea: Offers a delicate, complex flavor with multiple layers, ranging from sweet and slightly astringent to a lingering aftertaste. Suitable for tea connoisseurs who enjoy natural flavors.
- CTC Black Tea: Delivers a bold, strong taste with a quick release of astringency. Ideal for tea bags, milk tea, and beverages that require a robust flavor.
- Practical Applications
- Orthodox Black Tea: Best suited for premium tea lines, whole-leaf brews, and consumers who prefer a refined tea experience.
- CTC Black Tea: Commonly used in tea bags, milk teas, and drinks requiring a fast, strong brew.
- Conclusion
Both Orthodox and CTC methods have their own strengths, serving different market segments. Orthodox tea provides elegance and a slow, enjoyable tea-drinking experience, while CTC tea offers convenience and intense flavor. Businesses should clearly identify their market needs to select the most suitable type of black tea.
