In short: Danau Kembar is a tea estate in West Sumatra, Indonesia, operated by PT Perkebunan Nusantra VI and known to supply Morrisons.
Danau Kembar is a tea estate located in West Sumatra, Indonesia, positioned at approximately 358 metres above sea level. The estate is operated by PT Perkebunan Nusantra VI, one of Indonesia's state-owned plantation companies, and is recorded as a supplier to the British supermarket chain Morrisons. The estate produces both black and green teas.
Terroir & Climate
At 358 metres elevation, Danau Kembar occupies a relatively low-altitude position for tea cultivation, particularly when compared to the high-elevation estates found elsewhere in Indonesia and across Asia. Estates at this elevation in equatorial Sumatra typically experience warm, humid conditions year-round, with limited seasonal temperature variation. Such environments tend to encourage vigorous vegetative growth, and the lack of significant cold stress or dormancy periods generally results in a faster-growing flush cycle.
West Sumatra's tropical climate, characterised by heavy rainfall and consistent warmth, tends to produce leaf with a different metabolic profile than that from cooler, high-altitude gardens. Lower elevation often correlates with larger leaf, faster oxidation rates during processing, and a tendency toward bolder, more astringent liquor in black teas. Green teas from such regions may likewise exhibit a more robust, less delicate character than their high-mountain counterparts, though processing choices remain the dominant variable.
Tea Produced
Danau Kembar produces both black and green teas. Black teas from lower-elevation Indonesian estates typically yield a straightforward, robust cup with malty or earthy notes and a degree of astringency; they are often valued for blending or for markets that favour strength over nuance. Green teas from similar terroir tend to be more vegetal and full-bodied than the lighter, more aromatic styles associated with cooler highland gardens, though the estate's specific processing protocols will ultimately determine the final cup profile. Both styles are likely to reflect the vigorous growth and warm, humid conditions characteristic of West Sumatra's lower slopes.
Supply Chain & Market Position
Danau Kembar is recorded as a supplier to Morrisons, one of the United Kingdom's largest supermarket chains. This relationship places the estate within the supply chain for mainstream, price-competitive retail tea—a segment that prioritises consistent volume, food-safety standards, and cost efficiency. Supplying a major UK grocer indicates that Danau Kembar meets the traceability and quality assurance expectations of large-scale European buyers, and that its output is suited to blending or own-label products destined for the mass market.
