Thammenna

Thammenna is a tea estate located in the Southern Province of Sri Lanka, operating at an elevation of 129 metres above sea level. The estate produces black tea and is recorded as supplying Finlays, one of the world's largest tea and coffee businesses. The operator of the estate is not publicly documented in available trade records.

Terroir & Climate

At 129 metres above sea level, Thammenna occupies the low-grown category of Sri Lankan tea production, a designation that typically applies to estates below 600 metres. This elevation, combined with the Southern Province's proximity to the equator at latitude 6.27°N, tends to produce a warm, humid growing environment with less diurnal temperature variation than found in the island's high-grown districts. Low-grown estates in Sri Lanka generally experience faster shoot growth and can support year-round plucking, though the most active flush periods often align with the southwest and northeast monsoon patterns that shape the island's climate.

The Southern Province lies outside the traditional Dimbula, Nuwara Eliya, and Uva districts more commonly associated with Ceylon tea, but low-elevation production in this region typically benefits from consistent warmth and moisture. Estates at this altitude often yield leaf with a brisker, more robust character than the delicate, high-grown teas, though specific soil composition, cultivar selection, and processing methods will significantly influence the final cup.

Tea Produced

Thammenna produces black tea, the dominant category across Sri Lanka's low-grown estates. Teas from this elevation band in Sri Lanka typically yield a full-bodied, brisk cup with good colour and strength, characteristics that tend to suit blending applications and markets where robust flavour is valued. Low-grown Ceylon blacks generally offer less aromatic complexity than their high-grown counterparts but provide consistency, depth, and a malty or slightly earthy character that performs well in breakfast blends and chai formulations.

Supply Chain & Market Position

Thammenna is recorded as a supplier to Finlays, a vertically integrated agribusiness with extensive tea-trading, blending, and packing operations serving multinational brands and retail buyers. Finlays sources from estates across all major origins, and its presence in the supply chain typically indicates that Thammenna's production enters commercial blending streams destined for international markets. This relationship suggests the estate's output meets the quality and volume benchmarks required by large-scale buyers, though the specifics of contracted tonnage and exclusivity are not publicly disclosed.
