Terroir & Climate
At 15 metres elevation, Rehana Cha Karkhana sits in the lowland tea-growing zone of Sylhet, where estates typically experience warm, humid conditions year-round. This latitude and altitude combination generally supports a vigorous growing cycle, with minimal dormancy; estates at similar elevations in the region often harvest flush cycles throughout much of the year, particularly during the monsoon and post-monsoon months when rainfall and temperature peaks tend to drive rapid leaf expansion.
Lowland estates in Sylhet typically benefit from alluvial or valley soils, which can retain moisture well during the wet season. The lack of significant elevation means that diurnal temperature variation is modest, and the growing environment tends to favour volume and robustness over the more delicate aromatic complexity sometimes associated with higher-altitude gardens. Drainage and soil management become particularly important in such low-lying settings, where waterlogging during monsoon periods can influence root health and leaf chemistry.
Tea Produced
Rehana Cha Karkhana produces black tea. Lowland estates in Sylhet generally yield teas with a full body, brisk character, and较强 malty or earthy notes. The warm, humid growing conditions typical of this elevation tend to produce leaf that, when fully oxidised, results in a robust, straightforward cup—often well-suited to blending or to markets that favour strength and colour over nuanced aroma. Estates at similar altitudes in the region are sometimes noted for teas with a darker liquor and a pronounced astringency, particularly from leaf harvested during the hotter months.
