Sithaka Tea Factory

Sithaka Tea Factory is a black tea production facility located in Colombo District, Sri Lanka, operating at an elevation of 30 metres above sea level. The estate is managed by Avissawella Tea Factory, a company that operates multiple tea production sites in the country.

Terroir & Climate

At 30 metres above sea level, Sithaka Tea Factory occupies one of the lowest elevations at which tea is grown in Sri Lanka, placing it firmly in the low-grown category that characterises much of the island's coastal and near-coastal production. Estates at this altitude typically experience warmer, more humid conditions year-round compared to the cooler mid- and high-grown districts, which tends to encourage faster leaf growth and more vigorous vegetative cycles.

The Colombo District's proximity to the equator and low elevation generally results in consistent temperatures with less diurnal variation than is found in the central highlands. These conditions often favour rapid cropping and can yield leaf that is bolder and more robust in structure, though the specific growing environment at Sithaka will also be shaped by local rainfall patterns, soil composition, and the factory's field management practices.

Tea Produced

Sithaka Tea Factory produces black tea, the dominant style across Sri Lanka's low-grown estates. Teas from this elevation band typically yield a full-bodied, brisk cup with strength and colour, characteristics that are generally valued in blending and in markets where robust, straightforward character is preferred. The quick-growing leaf from lower altitudes often lacks the aromatic complexity and brightness associated with high-grown Ceylon teas, but tends to deliver consistency and body, qualities that have long underpinned the commercial appeal of Sri Lanka's low-grown production.

Operator

Avissawella Tea Factory operates Sithaka Tea Factory and at least one other tea estate recorded in industry directories. The presence of multiple production sites suggests a degree of operational scale, though the structure and ownership of the company, and its broader supply-chain relationships, remain outside the scope of publicly available trade records.
