Karnafully Tea Estate

Karnafully Tea Estate is a black tea producer located in the Chattogram region of Bangladesh, operated by Karnafully Tea Estate. Situated at approximately 11 metres above sea level, the estate occupies low-lying terrain in the southern part of the country's tea-growing belt. No commercial buyers are currently recorded in public supply-chain data for this operation.

Terroir & Climate

At just 11 metres above sea level, Karnafully Tea Estate occupies one of the lowest elevations among Bangladesh's recorded tea gardens. Estates at this altitude in the Chattogram region typically experience a warm, humid tropical climate shaped by proximity to the Bay of Bengal, with the monsoon season bringing substantial rainfall and little thermal variation between day and night. Such low-lying terrain generally supports vigorous vegetative growth year-round, though the absence of elevation means fewer of the diurnal temperature swings that can concentrate certain secondary metabolites in the leaf.

The combination of high ambient temperatures and consistent moisture typical of this latitude and elevation tends to favour rapid flush cycles and high-yield plucking schedules. Estates in similar lowland environments often contend with the agronomic challenges of heavy rainfall and humidity, which can influence both cultivation practices and the post-harvest processing required to achieve stable fermentation and drying. The flatness of the landscape may also affect drainage and microclimate, factors that can shape the character of the made tea.

Tea Produced

Karnafully Tea Estate produces black tea. Estates at very low elevations in Bangladesh typically yield full-bodied, malty liquors with robust, straightforward character rather than the aromatic complexity associated with high-grown leaf. The warm growing conditions and rapid flush turnover common to lowland gardens in Chattogram tend to produce teas well suited to blending and to markets that favour strength and colour over nuance. Such teas often exhibit a brisk, assertive profile with moderate astringency, though cup character can vary with the season and the specific manufacturing protocols employed.
