Chaay in India

The tea plant, known as चाय Chaay (Hindi), தேய் Tey (Tamil), Teyaku (Telugu), ತೇ Tea (Kannada), Tey (Malayalam), चहा Chahaa (Marathi), is the source of Assam and Darjeeling tea, among India's best-known agricultural exports. Camellia sinensis is grown across Tamil Nadu, West Bengal, Assam, Uttarakhand, Kerala, Himachal Pradesh, mostly on hill slopes with reliable rainfall.

Uses

Young leaves and leaf buds are plucked and processed (withered, rolled, oxidised and dried) into the black, green or oolong tea drunk daily across the country; different oxidation levels give the different tea types from the same leaf.

How to Identify Chaay

An evergreen shrub, kept low and bushy by regular plucking on estates but capable of growing into a small tree if left unpruned. Leaves are glossy, dark green, finely toothed and leathery. Flowers are white with a prominent cluster of yellow stamens, fragrant, appearing singly or in small groups.

Frequently Asked Questions

What is Tea plant called in different Indian languages?
चाय Chaay (Hindi); தேய் Tey (Tamil); Teyaku (Telugu); ತೇ Tea (Kannada); Tey (Malayalam); चहा Chahaa (Marathi); চা Cha (Bengali).
Do green tea and black tea come from the same plant?
Yes — both (and oolong) come from Camellia sinensis; the difference is how much the picked leaf is oxidised before drying, not a different plant.
Why is Darjeeling tea considered special?
Its distinct flavour comes from the specific high-altitude growing conditions and cultivar selections used there, similar to how terroir shapes wine.
