Co, Op Win

Co, Op Win is a tea estate located in the Southern Province of Sri Lanka, situated at an elevation of approximately 46 metres above sea level. The estate is operated by Co and is known to supply Finlays, one of the major buyers in the global tea trade. Production is focused on black tea.

Terroir & Climate

At 46 metres above sea level, Co, Op Win occupies low-elevation terrain in Sri Lanka's Southern Province, a markedly different growing environment from the island's celebrated highland zones. Estates at this latitude and altitude typically experience warm, humid conditions year-round, with less pronounced diurnal temperature variation than is found in the mid- and high-grown districts. Such environments generally favour rapid vegetative growth and high yields, though the leaf character tends to differ from that produced in cooler, slower-maturing highland settings.

Low-elevation tea gardens in southern Sri Lanka are often subject to the influence of both monsoon periods, with the southwest monsoon typically affecting the region from May to September and the northeast monsoon from December to February. These moisture patterns, combined with consistently warm temperatures, tend to support continuous cropping cycles throughout much of the year, though seasonal quality variation is common across estates in similar climatic zones.

Tea Produced

Co, Op Win produces black tea, the dominant category manufactured at low-elevation estates across Sri Lanka's Southern Province. Teas from this elevation band typically yield a brisk, full-bodied cup with good colour and strength, characteristics that are often valued in blending for both packet tea and foodservice applications. The leaf grown at lower altitudes generally matures more quickly than high-grown material, and the resulting liquor tends to be robust and malty rather than delicate or aromatic, though specific cup character will vary with factory processing and seasonal conditions.

Supply Chain & Market Position

Co, Op Win is recorded as supplying Finlays, a vertically integrated tea business with operations spanning estate production, blending, and global distribution. Finlays sources from multiple origins and manages estates as well as third-party supply relationships across Africa and Asia. The presence of Finlays as a known buyer suggests that Co, Op Win's output enters a professional supply chain serving international blenders, brand owners, and retail markets, though the specific end-use of the estate's production has not been publicly detailed.
