Derangala

Derangala is a tea estate located in Sri Lanka's Southern Province, positioned at an altitude of 224 metres above sea level. The estate produces black tea and is recorded as a supplier to Finlays, the international tea and horticulture company. The operating entity is not currently documented in public records.

Terroir & Climate

At 224 metres above sea level, Derangala occupies the low-grown category of Sri Lankan tea production, a designation that typically begins below 600 metres. Estates at this elevation in the Southern Province generally experience warmer temperatures and higher humidity than their high-grown counterparts, conditions that tend to promote faster leaf growth and year-round cropping cycles. The southern districts of Sri Lanka, at this latitude close to six degrees north of the equator, do not experience the pronounced monsoon patterns that shape production in the island's central and eastern regions, though seasonal rainfall variation still influences flush timing.

Low-grown Sri Lankan teas are often associated with fuller leaf development and a growing environment that favours yield and consistency over the slower, more delicate leaf maturation seen at higher elevations. Estates in this altitude band generally benefit from reliable warmth and moisture, though the specific microclimate, soil composition, and cultivar selection at any given site will shape the character of the made tea.

Tea Produced

Derangala produces black tea, the dominant style across Sri Lanka's low-grown estates. Teas from this elevation and region typically yield a cup with good body, deeper colour, and a straightforward, robust character. Low-grown Ceylon blacks are generally less delicate than high-grown teas from Nuwara Eliya or Dimbula, instead offering strength and consistency that suits blending applications and markets where full-bodied, dependable character is valued. While individual estate practice and processing methods will vary, the altitude and climate at Derangala would tend to support this profile.

Supply Chain & Market Position

Derangala is recorded as supplying Finlays, a vertically integrated business with extensive tea estates, processing facilities, and blending operations across multiple origin countries. Finlays' customer base includes major international tea brands and retailers, suggesting that Derangala's output is likely destined for blending and branded products in export markets. The relationship positions the estate within a supply chain serving large-scale commercial buyers rather than niche or estate-specific retail channels.
