Green House

Green House is a tea estate located in the Southern Province of Sri Lanka, operating at an altitude of just 8 metres above sea level. The estate produces black tea and is known to supply Finlays, a major participant in the global tea trade. The operator of the estate is not currently recorded in publicly available supply-chain data.

Terroir & Climate

At 8 metres altitude, Green House occupies one of the lowest elevations at which tea is commercially cultivated in Sri Lanka. Estates at such low elevations in the Southern Province typically experience warm, humid conditions year-round, with minimal temperature variation between day and night. This warmth generally accelerates the growing cycle, allowing for frequent plucking rounds and vigorous vegetative growth, though the leaf chemistry tends to differ from that of high-grown Ceylon teas.

Southern Province low-grown estates often contend with higher rainfall and humidity levels than their counterparts in the central highlands, conditions that can favour rapid flush production but also demand careful estate management. The near-sea-level elevation and proximity to the coast typically result in less pronounced dormancy periods, meaning that production can continue almost year-round, though seasonal monsoon patterns still influence the character and volume of the crop.

Tea Produced

Green House produces black tea, a style that is the mainstay of Sri Lanka's low-grown production. Teas from estates at this elevation in the Southern Province typically yield a cup that is full-bodied and robust, often with stronger, maltier notes than the bright, brisk high-grown Ceylon styles. The warm growing conditions tend to produce leaf that processes into bold, dark liquors with good strength, characteristics that make low-grown Ceylon blacks well-suited to blending and to markets where body and colour are prioritised over the more delicate aromatics of high-elevation leaf.

Supply Chain & Market Position

Green House is recorded as a supplier to Finlays, one of the world's largest tea and coffee companies with extensive blending, packing, and distribution operations across multiple continents. This connection positions Green House within a major international supply chain, indicating that its production is likely destined for blended retail products or foodservice channels rather than single-estate offerings. Finlays' broad buyer base suggests that tea from Green House may ultimately reach supermarkets, tea brands, and institutional customers in numerous markets, though the estate's output would typically be aggregated with other origins in finished blends.
