Sewpur

Sewpur is a tea estate located in Assam, India, at an elevation of approximately 125 metres above sea level. The estate is operated by Chamong Tee Exports Pvt. Ltd., a company with extensive tea holdings across India's growing regions. Sewpur is known to supply Morrisons, the British supermarket chain, and holds certification from the Ethical Tea Partnership.

Terroir & Climate

At 125 metres elevation in the Brahmaputra valley plains, Sewpur occupies terrain typical of lowland Assam estates. This altitude range generally experiences high temperatures and significant humidity throughout the growing season, conditions that tend to promote vigorous vegetative growth. Estates at this elevation in Assam typically benefit from deep alluvial soils deposited by the river system, which often support robust tea bushes capable of sustained cropping.

The latitude of approximately 27.5°N places Sewpur firmly within the monsoon belt, where estates typically experience a pronounced wet season from May through September. This climatic pattern tends to drive a flush cycle in which the heaviest leaf production coincides with peak rainfall and warmth. Lower-elevation Assam gardens generally see less diurnal temperature variation than their counterparts in the hills, a factor that often contributes to the full-bodied, malty character for which the region is known.

Tea Produced

Sewpur produces black tea, the dominant category across Assam's lowland estates. Teas from gardens at this elevation in the Brahmaputra valley typically yield a robust, full-bodied cup with the malty sweetness and brisk astringency that define orthodox Assam character. The region's climatic conditions tend to favour teas well suited to breakfast blends and products where strength and colour are valued, though specific cup profiles will vary by season, manufacturing method, and leaf grade.

Supply Chain & Market Position

Sewpur is recorded as a supplier to Morrisons, one of the United Kingdom's leading supermarket chains. This relationship places the estate within the supply chain for consumer-facing own-label tea products, a segment that demands consistent quality, traceability, and adherence to ethical sourcing standards. Supplying a major British retailer indicates that Sewpur's output meets the volume, quality benchmarks, and certification requirements typical of that market, and suggests integration into established export channels linking Assam producers with European buyers.

This multi-estate structure typically allows for blending flexibility, economies of scale in processing and marketing, and a presence across different quality segments and geographic denominations within the Indian tea sector.

Certifications & Ethics

Sewpur holds certification from the Ethical Tea Partnership, a multi-stakeholder initiative that works to improve social, environmental, and economic conditions on tea estates. ETP certification indicates that the estate has undergone monitoring against the partnership's standards, which address labour rights, health and safety, and environmental stewardship. For buyers—particularly those serving European and North American markets—this certification provides a degree of assurance regarding supply-chain due diligence and the working conditions of the estate's workforce.
