Rahana tea Factory

Rahana Tea Factory is a black tea producer located in Moulvibazar, in the Sylhet Division of Bangladesh. The factory operates at an elevation of approximately 15 metres above sea level, making it one of the lowland tea production sites in a country whose tea industry is concentrated in the north-eastern districts. The operator is listed as Rahana Tea Factory itself, and no affiliated estates have been recorded.

Terroir & Climate

At 15 metres elevation, Rahana Tea Factory occupies lowland terrain characteristic of much of the Moulvibazar district, where the Surma Valley and surrounding plains support tea cultivation in conditions markedly different from the higher-altitude gardens found elsewhere in South Asia. Estates at this latitude—around 24.5°N—and elevation typically experience a warm, humid subtropical climate with pronounced monsoon rains from May through September. The low altitude generally results in higher ambient temperatures year-round, which tends to accelerate the growing cycle and can yield vigorous vegetative growth.

In such lowland settings, drainage and soil management are often critical; the flat or gently undulating topography means that water management during the monsoon season requires careful attention. The heat and moisture typical of this elevation band often favour robust leaf development, and the lack of the temperature extremes or diurnal swings found at higher elevations tends to produce a different flavour profile from hill-grown teas. Bangladesh's tea-growing regions generally benefit from alluvial or clay-loam soils, though specific soil composition varies by site.

Tea Produced

Rahana Tea Factory produces black tea, the dominant style in Bangladesh's export and domestic markets. Teas from lowland estates in Moulvibazar typically yield a full-bodied, malty cup with good colour and strength, characteristics that are often associated with the warm growing conditions and the cultivars traditionally planted in the region. The lack of high-altitude astringency generally results in a smooth, rounded liquor, though individual factory processing and leaf grade will of course shape the final character. Such teas are commonly employed in blends where body and consistency are valued.
