Terroir & Climate
At 107 metres elevation in the Brahmaputra valley, Dirai occupies lowland terrain characteristic of Assam's principal tea-growing belt. Estates at this latitude and altitude typically experience a warm, humid subtropical climate with abundant monsoon rainfall, conditions that generally promote vigorous vegetative growth and a long cropping season. The plains of Dibrugarh tend to see little diurnal temperature variation, which often results in steady, rapid flush cycles during the growing months.
Tea grown at this elevation in Assam is typically harvested from spring through late autumn, with peak production usually coinciding with the second flush period in early summer. The combination of alluvial soils, warmth, and moisture in this region generally favours high yields and the development of strongly flavoured leaf, though specific soil composition and microclimate can vary considerably even within a single district.
Tea Produced
Dirai produces black tea, the dominant style in Assam. Teas from lowland estates in Dibrugarh district typically yield a robust, full-bodied cup with malty and brisk characteristics, often showing the bold, astringent profile for which Assam is known in the blending and commodity markets. The warm growing conditions at this elevation tend to favour teas with strong colour and body, though cup character can vary significantly depending on plucking standards, season, and processing.
