In short: Surma Tea Estate is a black tea producer in Habiganj, Bangladesh, operating at just 9 metres above sea level in the northeastern tea-growing lowlands.
Surma Tea Estate is a black tea producer located in Habiganj, a district in northeastern Bangladesh known for its concentration of tea cultivation. The estate operates at an altitude of just 9 metres above sea level, placing it firmly within the low-lying plains that characterise much of Bangladesh's tea country. It is operated under the name Surma Tea Estate.
Terroir & Climate
At 9 metres elevation and positioned at approximately 24°N latitude, Surma occupies terrain typical of the Bangladesh lowlands, where high temperatures, heavy monsoon rains, and high humidity dominate the growing environment. Estates at this elevation in the region generally experience minimal diurnal temperature variation compared to highland tea zones, and the growing cycle tends to be vigorous and continuous during the wet season, with little dormancy imposed by cold.
The Habiganj area sits within the floodplain and wetland systems of northeastern Bangladesh, where drainage, water management, and soil composition—often alluvial in character—tend to exert a strong influence on cultivation practices. Such low-altitude estates typically contend with intense heat and moisture during the monsoon months, which can favour rapid leaf growth but also require careful agronomic management to maintain quality.
Tea Produced
Surma produces black tea. Estates in the Bangladesh lowlands, particularly those at single-digit elevations, typically yield teas with robust body, malty or earthy depth, and a brisk, assertive cup character. The warm, humid growing conditions generally favour vigorous leaf development, and the black teas produced in this region often display strength and colour well suited to blending or to markets that favour full-bodied infusions.
