Terroir & Climate
At 16 metres above sea level, Sirajnagor Tea Estate occupies low-lying terrain typical of Bangladesh's lowland tea zones. Estates at this elevation generally experience warm, humid conditions year-round, with minimal diurnal temperature variation compared to hill-grown counterparts. The subtropical latitude of approximately 24.5°N tends to support vigorous vegetative growth, and the flat topography is often associated with deeper alluvial soils that retain moisture during the monsoon season.
The Moulvibazar region typically receives heavy rainfall during the south-west monsoon, which usually drives peak flush periods between May and September. Low-elevation gardens in this climatic zone often benefit from the combination of warmth, humidity, and ample water availability, conditions that generally favour rapid leaf development. However, the absence of altitude-related stress means that leaves may mature more quickly, a factor that can influence both yield and cup character.
Tea Produced
Sirajnagor Tea Estate produces black tea. Estates in Bangladesh's lowland zones, particularly those at elevations below 50 metres, typically yield teas with a robust, malty body and a straightforward, brisk cup profile. The warm growing conditions and rapid leaf maturation common at this altitude often result in liquors that are strong and full-bodied, well-suited to blending and to markets that favour bold, assertive character. The cup profile is generally less complex than that of high-grown teas, with emphasis on strength and colour rather than aromatic nuance.
