Major Tea Regions in India
India has 28 states, 16 of which are involved in tea cultivation. The country primarily produces Orthodox black tea and CTC (Crush, Tear, Curl) black tea, which together account for about 99% of total production. The remaining 1% consists mainly of green tea.
The main tea-growing regions include:
- Darjeeling
- Assam
- Nilgiri
- Kangra
- Munnar
- Dooars-Terai
Among these, Darjeeling, Assam, and Nilgiri are the most renowned, each with its own unique geographical identity and tea profile.
Tea Cultivation and Production in India
Tea production in India is organized around estates, which can be large plantations or smallholder farms. Large estates typically have their own processing facilities and manage everything from cultivation to manufacturing. Small-scale farmers usually sell their fresh leaves to larger estates, buying stations, or cooperatives for processing.
The core stages of black tea processing remain consistent across regions:
- Withering: Fresh tea leaves are spread out to reduce moisture content.
- Rolling/Cutting: Leaves are rolled (for Orthodox tea) or cut (for CTC tea).
- Fermentation: Exposure to air allows oxidation to develop flavor and color.
- Drying: Halts the oxidation process.
- Grading: Tea is sorted by leaf size and appearance.
- Packaging: Ready for market distribution.
