Coombergram

Coombergram is a tea estate located in the Jorhat district of Assam, India, at an elevation of approximately 155 metres. The estate is operated by Goodricke Group and is known to supply Morrisons, the British supermarket chain. It produces black tea.

Terroir & Climate

At 155 metres above sea level, Coombergram occupies a low-elevation position typical of the upper Assam plains near Jorhat. Estates at this altitude generally experience the region's monsoon-driven climate, with high rainfall and warm, humid conditions that tend to support vigorous vegetative growth throughout much of the year. The latitude of approximately 24.9°N places the estate well within the tropical to subtropical belt, where temperatures remain relatively consistent and frost is rare.

These conditions typically favour rapid leaf development and high yields. The combination of warmth, moisture, and alluvial soils common to the Brahmaputra valley often results in teas with pronounced body and malt character, though specific outcomes naturally depend on processing and seasonal variation. Estates in this part of Assam generally produce the bulk of their crop during the main monsoon flush, with a smaller but often prized second flush earlier in the season.

Tea Produced

Coombergram produces black tea. Assam estates at this elevation typically yield teas known for their full body, malty sweetness, and brisk astringency—a profile well suited to breakfast blends and strong, milk-friendly infusions. Jorhat-district teas often exhibit a robust, straightforward character with notes that can range from malt and toast to darker, more earthy tones depending on the flush and processing. While individual garden character varies, low-altitude Assam black teas of this type are generally valued for strength and consistency rather than delicate complexity.

Supply Chain & Market Position

Coombergram is recorded as a supplier to Morrisons, one of the United Kingdom's major supermarket chains. This relationship places the estate within the supply chain for mainstream British retail tea, a sector that prioritises volume, consistency, and value. Supplying a large grocer typically indicates that the estate's output meets the specifications required for blended products sold under own-label or branded lines in the mass market. While a single known buyer does not capture the entirety of an estate's commercial relationships, the Morrisons link suggests that Coombergram's production is integrated into large-scale, quality-controlled supply programmes characteristic of modern supermarket tea sourcing.
