Largest Tea Producing State in India: Assam Output

Assam is the largest tea producing state in India, contributing over 50% of the country's total annual tea production. Blessed with abundant monsoon rainfall, fertile acidic alluvial plains along the Brahmaputra and Barak river valleys, and a warm, humid tropical climate, Assam is world-renowned for its brisk, robust, and malty black teas.

Why Assam dominates Indian tea production

Assam's tea estates are concentrated in the Upper Assam districts of Dibrugarh, Tinsukia, Sibsagar, and Jorhat. The state features deep, fertile, loamy soils with optimal soil acidity (pH 4.5 to 5.5) and receives 1500 to 2500 mm of annual rainfall alongside hot, humid conditions that encourage rapid vegetative flushes of Camellia sinensis var. assamica.

  • Production volume: Produces over 50% of India's total annual tea harvest.
  • First and second flush: Premium second flush harvested in May-June delivers the celebrated rich malty flavor and bright amber liquor.
  • Small tea growers: Over 100,000 smallholder growers cultivating small tea plots contributing over half of the state's green leaf output.

Other major tea producing states in India

  • West Bengal: Second-largest producer, encompassing the world-famous muscatel Darjeeling hill teas and high-volume Dooars and Terai plains.
  • Tamil Nadu and Kerala: Major southern producers in the Nilgiri, Anamallai, and Munnar hill ranges, famous for aromatic, golden liquor teas harvested year-round.
  • Himachal Pradesh (Kangra) and Tripura: Cultivating specialty orthodox and green teas.

Regulatory oversight by the Tea Board of India

The Tea Board of India, functioning under the Ministry of Commerce and Industry, regulates tea registration, plantation replanting subsidies, research funding (such as TRA Tocklai), and export quality certifications.
