Marybong Tea Estate is a black-tea producer located in West Bengal, India, at an elevation of 2,016 metres. The estate is operated by Chamong Tee Exports Pvt. Ltd., a company that manages multiple tea properties in the region. Marybong is known to supply Sainsbury's, the major British supermarket chain, and holds certification from the Ethical Tea Partnership.
Terroir & Climate
At 2,016 metres, Marybong sits well within the high-elevation band that typically characterises the prime tea-growing zones of West Bengal's Darjeeling district. Estates at this altitude generally experience cooler temperatures, greater diurnal variation, and slower leaf maturation than their lower-elevation counterparts. These conditions tend to favour the development of aromatic complexity and a more structured astringency in the finished tea.
The latitude—just above 27°N—places Marybong in the sub-Himalayan belt, where monsoon systems and altitude interact to create a climate often marked by well-defined seasonal flushes. High-elevation estates in this region typically contend with mist, significant rainfall during the monsoon months, and cooler winters, all of which shape the annual growing cycle and tend to slow vegetative growth, concentrating flavour compounds in the leaf.
Tea Produced
Marybong produces black tea. Estates at similar elevations in West Bengal typically yield teas with bright, brisk liquor and a balance of muscatel sweetness and astringency, characteristics often associated with high-grown Darjeeling-style production. The slower maturation at altitude tends to support the development of aromatic esters and polyphenols, though the precise cup profile will vary by flush, manufacturing method, and the skill of the estate's tea makers.
Supply Chain & Market Position
Marybong's recorded supply relationship with Sainsbury's positions the estate within the mainstream British retail tea market. Sainsbury's sources Darjeeling and other Indian teas for both own-label lines and, occasionally, traceable single-estate offerings, suggesting that Marybong's production meets the volume, consistency, and audit standards required by a major supermarket chain. This relationship indicates a degree of commercial scale and a supply-chain infrastructure capable of meeting UK import and food-safety requirements.
