Terroir & Climate
At 52 metres above sea level, Kokrajhar occupies low-lying terrain typical of Assam's river plains. Estates at this elevation in the region generally experience the warm, humid conditions and heavy monsoon rainfall that characterise the Brahmaputra valley, conditions that tend to support vigorous vegetative growth and year-round plucking cycles with a pronounced flush structure.
The low altitude and subtropical latitude typically mean that tea plants face little thermal stress, and the growing season extends across most of the calendar year. Estates in this zone often see their most concentrated cropping during the pre-monsoon first flush and the post-monsoon autumn period, when flavour compounds tend to be more concentrated than during the peak rains.
Tea Produced
Kokrajhar produces black tea. Assam leaf grown at this elevation typically yields a malty, full-bodied cup with the robust, brisk character for which the region is known. Teas from low-altitude Assam estates are often used in breakfast blends and builder's tea for their strength, colour, and tolerance of hard water, though cup profile varies with plucking standard, processing, and seasonal flush.
Supply Chain & Market Position
Kokrajhar is recorded as supplying Morrisons, one of the United Kingdom's largest supermarket groups. This relationship places the estate within a retail supply chain serving the mass market, where Assam black tea is a staple ingredient in own-label blends and everyday tea bags. Supplying a major British retailer suggests the estate meets the volume, consistency, and traceability standards expected by large-scale buyers in a competitive and price-sensitive category.
