Terroir & Climate
At 113 metres above sea level, Koilamari sits at a low elevation within the broader tea‑growing geography of north‑east India. Estates at this altitude typically experience warmer ambient temperatures and higher humidity than their high‑grown counterparts, conditions that generally favour vigorous vegetative growth and shorter intervals between plucking rounds. The latitude—just above 27°N—places the estate in a subtropical belt where the monsoon cycle tends to dominate the agronomic calendar, with a pronounced wet season that can influence both yield and leaf chemistry.
Low‑elevation gardens in this part of India often contend with greater pest and disease pressure owing to warmth and moisture, though these same conditions can support rapid canopy development. The rolling plains and river valleys characteristic of the region generally offer deep alluvial soils, which tend to produce generous flush volumes. However, the trade‑off is that teas from such elevations are often less complex in aroma and structure than those grown in the cooler, slower‑maturing environments found at higher altitude.
Tea Produced
Koilamari produces black tea. Estates at comparable elevation in north‑east India typically yield full‑bodied, malty liquors with robust colour and a straightforward flavour profile. Low‑grown teas from this latitude tend to brew strong and brisk, characteristics valued in blends and in markets where strength and colour are prioritised over aromatic complexity. The cup is generally less nuanced than that of high‑elevation Darjeeling or Nilgiri teas, though it offers consistency and weight that suit both domestic consumption and export commodity channels.

Certifications & Ethics
Koilamari holds certification from the Ethical Tea Partnership, a multi‑stakeholder initiative that monitors labour standards, environmental practices, and community welfare across member estates. ETP certification signals to buyers that the estate has committed to independent audit against the partnership's code, covering issues such as working hours, health and safety, wages, and the prohibition of child and forced labour. For procurement teams, the certification offers a degree of due‑diligence assurance, particularly where direct site visits are infrequent.
