In short: Koomber is a black tea estate in the Kumbhir region of India, operated by Goodricke Group at an elevation of 132 metres.
Koomber is a tea estate in the Kumbhir region of India, situated at an elevation of 132 metres above sea level. The estate is operated by Goodricke Group, one of the country's established tea producers. Koomber produces black tea, characteristic of the lowland growing zones in this part of India's north-east.
Terroir & Climate
At 132 metres, Koomber sits within the lowland tea-growing belt of the Barak valley in southern Assam and adjacent areas. Estates at this elevation typically experience warm, humid conditions year-round, with a long growing season that can yield multiple flushes. The low altitude generally means less diurnal temperature variation than in hill gardens, and the warm plains climate tends to encourage vigorous vegetative growth.
The Kumbhir region's position near 25°N latitude and its proximity to the Barak river basin typically bring heavy monsoon rainfall and high ambient humidity. These conditions often favour rapid leaf development and the production of robust, full-bodied teas. Lowland estates in this zone generally flush earlier in the season than their high-elevation counterparts and maintain production well into the autumn months.
Tea Produced
Koomber produces black tea. Estates in the Kumbhir lowlands at this elevation typically yield teas with a full body and malty character, often showing the brisk, robust profile associated with warm-grown leaf. The cup character tends to be straightforward and strong, with good colour and a certain weight on the palate. Such teas are often well-suited to blending and to markets that favour a bold, assertive infusion.
