Indian tea is both a vast everyday drink and a collection of highly specific origins. The same national industry contains strong Assam and Dooars CTC made for milk tea, seasonal Darjeeling lots measured in only a few million kilograms, fragrant Nilgiri orthodox tea, Kangra green tea and a growing field of white, oolong and small-batch experimental teas. “Indian tea” is therefore a useful country name; region, process and season complete the flavour description.

India is the world’s second-largest tea producer and the largest producer and consumer of black tea. Most of what it makes is drunk within the country. That domestic scale matters: the history of Indian tea includes the plantation-and-export story as well as tea stalls, household kettles, railway platforms, offices and countless local ways of preparing chai.

This guide connects those everyday cups with the gardens, factories and regions behind them. For the wider geographic context, begin with our guides to tea-producing countries and tea-growing regions.

India in the world tea landscape

Tea Board of India’s final calendar-year figures put national production at 1,395.53 million kilograms in 2025. Assam supplied just over half and West Bengal another 30%. Tamil Nadu and Kerala formed the southern core, while smaller volumes came from Karnataka and a wide group of Himalayan, northeastern and eastern states.

The process split shows what those totals mean in the cup. In 2025 India made 1,227.66 million kilograms of CTC tea, 149.04 million kilograms of orthodox tea and 18.83 million kilograms of green tea. CTC therefore represented about 88% of production, orthodox tea about 11% and green tea a little over 1%. White and oolong teas form a small speciality field outside those three main statistical categories.

India’s principal producing areas in 2025
Area 2025 production What the figure contains
Assam 699.58 million kg Assam Valley and Cachar; predominantly CTC, with an important orthodox sector
West Bengal 421.63 million kg Dooars, Terai and Darjeeling; the first two account for almost all of the volume
Tamil Nadu 171.63 million kg Nilgiri and other southern districts, making both CTC and orthodox tea
Kerala 58.16 million kg Principally the Munnar and Idukki highlands, Wayanad and smaller districts
Other states 44.53 million kg Karnataka and smaller origins including Tripura, Himachal Pradesh, Sikkim and newer northeastern clusters

Large estates now share the supply chain with a vast small-grower sector. As of March 2025, the official register contained 1,567 estates and 249,318 small tea growers. Tea Board’s production table attributes 790.52 million kilograms—about 57% of the 2025 crop—to small growers. Many sell fresh leaf to bought-leaf factories rather than processing it on their own farm. An Indian tea may consequently be traceable to an estate, a small-grower group, a factory or a blend assembled from several sources.

The home market absorbs most of this tea. A Tea Board consumption study estimates that 83% of Indian production is consumed domestically. India still exported 262.98 million kilograms in the 2024–25 financial year. Domestic consumption remains the larger part of the country’s tea identity.

India’s major tea regions

Assam: lowland scale and distinctive orthodox tea

Assam’s tea country follows the humid Brahmaputra Valley across the north of the state and the lower Barak Valley around Cachar in the south. Warm temperatures, heavy seasonal rain and vigorous large-leaf tea material support rapid growth and high yields. The result is India’s largest producing state and one of the foundations of the global black-tea trade.

Assam makes both CTC and orthodox tea. CTC supplies brisk colour, body and extraction for milk tea, tea bags and blends such as English Breakfast. Orthodox Assam ranges from broken leaf to bud-rich whole-leaf lots. The spring first flush can be comparatively lively and aromatic; the summer second flush is especially valued for a deeper amber liquor and combinations of malt, honey, dried fruit and spice. Season, cultivar, garden and manufacture still matter more than one regional tasting note.

The geographical indication is specifically Assam Orthodox. It protects defined orthodox tea from the region; Assam CTC belongs to the regional industry but has a different legal scope. Our separate Assam tea guide explores its gardens, seasons and grades in more detail.

Darjeeling: a small origin shaped by season

Darjeeling lies in the Himalayan hills of West Bengal, where registered gardens occupy steep slopes at roughly 600 to 2,000 metres. Tea Board’s certification system recognises tea grown and manufactured within 87 registered gardens in the defined area. Authentic Darjeeling is therefore a controlled origin with geographic and production requirements.

Harvest season is central to its identity. First-flush teas from the spring are often lightly made, with a bright, floral, citrus or green-fruit character. Second flush is fuller and may develop the ripe-fruit, spice and grape-like aroma described as muscatel. Monsoon tea tends to offer stronger colour and body, while autumnal tea can be rounder, warmer and less sharply floral. These are useful tendencies; every garden and year gives them a different expression.

Darjeeling’s international fame is out of proportion to its volume. It produced only 5.60 million kilograms in 2025—less than half of 1% of India’s total. A named garden, harvest year, flush and invoice or lot number are therefore meaningful buying details, especially when the tea is sold at a premium.

Dooars and Terai: the foothill engine of West Bengal

South and east of Darjeeling, the Terai plains and the Dooars belt stretch along the Himalayan foothills towards Assam. Their warm, wet growing conditions support large CTC crops with strong liquor, colour and practical value in blends. Together they produced 416.03 million kilograms in 2025—more than 74 times Darjeeling’s output.

Dooars and Terai tea is often encountered without the region named on a European packet. It may enter an Indian domestic blend, a breakfast blend or an export tea bag. Better traceability and more careful small-batch manufacture are also creating orthodox and speciality lots, but volume CTC remains the region’s economic centre.

Nilgiri and the southern highlands

The Nilgiri Hills rise where Tamil Nadu meets Kerala and Karnataka. Tea grows across a broad range of elevations, and the interaction of the southwest and northeast monsoons permits a long, often near year-round plucking season. Tamil Nadu makes large quantities of CTC as well as orthodox tea; the protected name is Nilgiri Orthodox.

Well-made Nilgiri orthodox tea can be bright and clean, with floral, citrus, wintergreen, spice or fresh-fruit notes depending on season and site. Some higher-elevation winter lots become markedly aromatic. Its clarity also makes Nilgiri useful for iced tea and scented tea, while stronger grades perform well with milk.

Kerala’s principal tea landscapes lie around Munnar and the wider Idukki highlands, with further production in Wayanad and smaller districts. Munnar is a separate highland origin from Nilgiri, with its own estates, factories and mix of CTC and orthodox styles. The Anamalai Hills of Tamil Nadu form another established southern district.

Kangra, Sikkim and smaller origins

Kangra tea grows in Himachal Pradesh between roughly 900 and 1,400 metres. Commercial planting began in the nineteenth century, and the protected geographical indication covers both black and green tea. Production is small; good labels name the garden, cooperative or maker and make the Himalayan origin precise.

Sikkim’s best-known garden is Temi, established in 1969 and now part of an organic tea sector. The state makes black, green, white and oolong teas on a modest scale. Tripura is principally a CTC origin with a smaller green-tea sector. Arunachal Pradesh, Meghalaya, Nagaland, Manipur, Mizoram, Uttarakhand and Bihar contain growing clusters of estates and smallholders, some focused on local CTC markets and others on traceable speciality lots. Each has its own plant material, climate, skills and market route.

What kinds of tea does India make?

Indian tea terms and what they tell you
Term What it describes Useful label details
CTC A rapid black-tea process that crushes, tears and curls the leaf into small granules Region or factory, grade, harvest period and whether it is a single origin or blend
Orthodox Black tea made through withering, rolling, oxidation and drying while retaining larger leaf structures Garden or maker, region, season, cultivar and leaf grade
First or second flush A seasonal harvest description, especially important in Darjeeling and Assam Year, garden, exact picking period and processing style
OP, BOP, FOP or FTGFOP Part of an orthodox leaf-size and appearance grading system Read the grade with origin and cup quality; the letters primarily describe the leaf sorting
Masala chai A prepared tea drink, usually combining tea with milk, sweetener and one or more spices Tea base, spices and whether flavours or extracts have been added

CTC and orthodox black tea

CTC means crush, tear, curl. After withering, machinery rapidly breaks the leaf and forms it into dense particles. Their high surface area produces colour, body and astringency quickly, which makes CTC well suited to boiling, milk, sugar and tea bags. Careful leaf selection, clean manufacture and good storage still separate lively CTC from coarse or stale tea.

Orthodox is a broad manufacturing route, and the finished tea may contain whole leaf, broken leaf, fannings or dust after sorting. Those grades mainly describe size and appearance; freshness, origin, manufacture and the cup determine whether a traceable BOP outperforms an anonymous FTGFOP. Our black tea guide explains both processes and the grading letters.

Green, white and oolong tea

India’s smaller categories extend well beyond black tea. Kangra, Assam, Darjeeling, Sikkim, Nilgiri and newer northeastern makers produce green tea, sometimes from material originally selected for black-tea manufacture. Makers also use buds and young leaf for white tea and apply controlled bruising and oxidation to create oolong. These teas can be excellent, and a processing description gives the country of origin its practical meaning. Look for the same garden, harvest and cultivar information expected from a good orthodox black tea.

From indigenous tea knowledge to a national industry

Tea belongs to a wider native range extending from the eastern Himalaya through southern China and northern mainland Southeast Asia. In Upper Assam, Singpho communities and neighbouring peoples knew, tended and prepared local tea plants before a British commercial industry existed. Their knowledge drew colonial attention to the region’s tea forests in the 1820s and 1830s.

The East India Company’s Tea Committee was formed in 1834, and experimental gardens tested both local Assam material and plants brought from China. Assam tea reached London in the late 1830s; the Assam Company was incorporated in 1839. Commercial cultivation then expanded through Assam and into Darjeeling, the Terai, Dooars, Kangra and the southern hills. Each district developed differently according to plants, labour, transport, rainfall and the export market it served.

Plantation growth depended on a large migrant workforce. In Assam, colonial recruitment systems moved labourers from central and eastern India under restrictive contracts and harsh conditions. Darjeeling estates recruited extensively from Nepal and surrounding Himalayan communities. Workers and their descendants created the skilled agricultural and factory knowledge on which the industry still relies.

After independence, ownership, regulation and markets changed. The Tea Act of 1953 established the framework under which Tea Board of India began operating in 1954. CTC manufacture expanded, domestic consumption grew and Indian businesses became central to production and branding. More recently, hundreds of thousands of small growers have altered the supply chain by selling green leaf to factories or forming producer groups and small processing units.

Chai and tea in Indian daily life

In Hindi and several other Indian languages, chai simply means tea. A cup called chai may be plain black tea, tea with milk and sugar, or a spiced preparation. Masala chai specifies the spiced family, whose recipes vary across regions, vendors and homes. Ginger, cardamom, clove, cinnamon, pepper, fennel or other spices may appear alone or in combination; households and vendors also vary the balance of water, milk, tea and sweetness.

The scale of today’s tea habit developed largely during the twentieth century. The Indian Tea Market Expansion Board began a major promotion campaign in 1935, presenting tea through advertisements, demonstrations and mobile sellers. Indian drinkers made the beverage their own: strong black tea, milk, sugar, spices and repeated boiling produced a practical drink very different from the export industry’s prescribed cup.

Tea now moves through homes, offices, factories, roadside stalls and railway stations. A clay kulhad is characteristic in some northern settings, while glass tumblers, steel cups and ceramic cups are common elsewhere. Kashmir adds its own tea traditions, including pink, salty noon chai and aromatic kahwa. Himalayan communities have further preparations. Indian tea culture is a network of regional and social practices.

Tea Board’s recent household study estimated 2023 domestic consumption at 1,197 million kilograms, or about 840 grams per person. More than 80% of surveyed tea drinkers preferred milk and sugar, and more than 90% drank tea before or with breakfast. Those findings help explain why brisk CTC is economically central even when speciality export writing gives more space to orthodox leaf.

People, climate and the value behind the leaf

Tea is one of India’s most labour-intensive rural industries. The organised sector employs about 1.156 million permanent and temporary workers; nearly 58% are women. Small growers, bought-leaf factories, transport, auctions, blending and retail support many more livelihoods. A photograph of plucking shows only one part of this system: pruning, field maintenance, weighing, factory work, tasting, sorting and logistics all shape the final tea.

Climate pressure is already practical rather than abstract. Erratic rain, floods, dry periods, higher temperatures and shifting pest pressure affect yields, plucking calendars and flavour. Ageing bushes, labour conditions, the price paid for green leaf and the cost of replanting also influence whether a garden or smallholder can invest for the long term. Useful sourcing questions therefore extend beyond a certification logo: who grew the leaf, who processed it, how precisely is the lot identified, and how does the seller support continuity at origin?

How to read an Indian tea label

A strong label separates place, process, season and grade. The following details are especially useful:

  • Region: Assam, Darjeeling, Dooars, Terai, Nilgiri, Munnar, Kangra or another precise origin tells you more than “India.”
  • Producer: Look for an estate, garden, cooperative, small-grower group, bought-leaf factory or named maker.
  • Process: CTC, orthodox black, green, white or oolong should be explicit.
  • Harvest: Year and season matter particularly for Darjeeling and fine orthodox Assam.
  • Grade: OP, BOP, FTGFOP, fannings and dust describe sorting; interpret them alongside origin and freshness.
  • Blend disclosure: A breakfast tea or masala-chai base may intentionally combine regions. A clear packet identifies it as a blend.

Four Indian tea names currently receive particular geographical-indication promotion from Tea Board: Darjeeling, Assam Orthodox, Nilgiri Orthodox and Kangra. Each has its own scope. Darjeeling certification covers tea grown and manufactured within its defined gardens; the Assam and Nilgiri names specify orthodox tea. A GI verifies defined origin and production requirements, while garden, season, storage and cup quality still distinguish individual lots.

How to brew Indian tea

Match the water and time to the finished style. The starting points below use 250 ml of water; adjust leaf and time to taste.

Starting points for brewing Indian loose-leaf tea
Style Leaf Water Time Adjustment
Assam or Dooars CTC 2–2.5 g 95–100 °C 2–3 minutes Shorten for a plain cup; add a little more leaf when brewing for milk
Assam orthodox 2.5–3 g 95 °C 3–4 minutes Second-flush and broken grades can take milk; delicate lots may be best plain
Darjeeling first flush 2.5–3 g 85–90 °C 2–3 minutes Use cooler water or less time if fresh green notes become sharp
Darjeeling second flush or autumnal 2.5–3 g 90–95 °C 3–4 minutes Try plain first; a fuller broken grade may suit a small amount of milk
Nilgiri or Kangra black tea 2.5–3 g 90–95 °C 3–4 minutes Cool and serve over ice only after brewing at full strength
Indian green tea 2.5–3 g 75–85 °C 1.5–2.5 minutes Follow the maker’s guidance when the leaf is especially fine or tightly shaped

For two small cups of masala chai, a practical starting point is 200 ml water, 100–150 ml milk, 5–7 g CTC tea, sugar to taste and a small amount of ginger, cardamom or another preferred spice. Simmer hard spices briefly in the water, add the tea for one to two minutes, then add milk and heat until the colour and strength suit you. Strain before serving. Treat the ratio as a framework and adjust it to your milk, spices and preferred strength.

For adaptable ratios, water advice and troubleshooting, see our beginner’s guide to loose-leaf tea.

India’s strength is its range

India’s tea identity comes from coexistence: enormous lowland CTC production and tiny seasonal Himalayan lots, estates and small growers, domestic chai and protected export origins. Assam, Darjeeling, Dooars, Nilgiri, Munnar and Kangra each become more useful when the label adds maker, process and harvest.
