In short: Langharjan Tea Estate is a black-tea garden in Naharkatia, Assam, India, operated by Jorehaut Group Ltd. and certified by the Ethical Tea Partnership.
Langharjan Tea Estate is a black-tea producer situated in the Naharkatia area of Assam, India, at an elevation of 122 metres above sea level. The estate is operated by Jorehaut Group Ltd., a company with holdings in the Assam tea sector. Langharjan holds certification from the Ethical Tea Partnership, though no buyers have been recorded in publicly available trade data.
Terroir & Climate
At 122 metres elevation in the Naharkatia tract of upper Assam, Langharjan lies within the low-altitude riverine belt that characterises much of the state's commercial tea country. Estates at this elevation in Assam typically experience warm, humid conditions year-round, with a pronounced monsoon season that sustains vigorous vegetative growth. The latitude of approximately 27°N places the garden in a subtropical zone where frost is absent and flush cycles can extend across much of the year.
Soils in the Naharkatia region are generally alluvial, derived from fluvial deposits, and tend to retain moisture well during the growing season. The combination of low elevation, ample rainfall, and consistent warmth usually favours high-yielding bushes that produce robust, malty leaf. Daytime temperatures during the main cropping months are typically high, which tends to accelerate biochemical processes in the leaf and contribute to the bold, brisk character for which low-altitude Assam teas are known.
Tea Produced
Langharjan produces black tea, the dominant manufactured type across Assam's low-elevation estates. Teas from gardens at this altitude in Naharkatia typically yield a full-bodied, malty cup with brisk astringency and a coppery infusion. The leaf grown at 122 metres tends to be broad and fleshy, well suited to orthodox or CTC processing, and generally delivers the robust, assertive profile that Assam is internationally recognised for, particularly in blends and breakfast-style infusions.

Certifications & Ethics
Langharjan holds certification from the Ethical Tea Partnership, a multi-stakeholder initiative that conducts independent monitoring of labour and environmental standards on member estates. ETP certification requires adherence to a code covering wages, working hours, health and safety, housing, and the prohibition of child and forced labour. For buyers, certification provides third-party assurance that baseline social and environmental criteria are subject to regular audit; for workers, it is intended to establish grievance mechanisms and promote continuous improvement in workplace conditions.
