Terroir & Climate

At 106 metres above sea level, Dirai sits in the low-lying plains characteristic of Assam's river valleys, where estates typically experience a humid, tropical climate with heavy monsoon rainfall and warm temperatures year-round. This combination of heat and moisture generally supports vigorous leaf growth and a long picking season, conditions that tend to favour the production of the robust, malty black teas for which Assam is known.

Estates at this elevation in the region often benefit from alluvial soils deposited by seasonal flooding, which can contribute to rich nutrient availability. The absence of significant altitude means that temperature variation between day and night is typically less pronounced than in high-grown regions, a factor that generally encourages rapid flush cycles and the bold, assertive character commonly associated with lowland Assam teas.

Tea Produced

Dirai produces black tea. Estates in Assam at similar elevations typically yield full-bodied liquors with malty, brisk profiles and a copper-to-reddish infusion. The warm, humid growing conditions common to the plains tend to produce leaf that brews strong and robust, often favoured for breakfast blends and CTC production, though orthodox manufacture can also yield teas with notable depth and astringency.

Luxmi Tea Co. Pvt. Ltd. operates Dirai alongside five other estates recorded in this directory, indicating a multi-property portfolio within the Indian tea sector.
