In short: Dayeuh Manggung Tea Estate is a black and green tea producer in Kabupaten Garut, Indonesia, operated by PTPN VIII and certified by the Ethical Tea Partnership.
Dayeuh Manggung Tea Estate is a production site in Kabupaten Garut, West Java, Indonesia, located at 1,088 metres above sea level. The estate is operated by PTPN VIII, one of Indonesia's state-owned plantation companies. It produces both black and green tea, though no specific downstream buyers have been publicly recorded in trade data.
Terroir & Climate
At 1,088 metres elevation in West Java, Dayeuh Manggung occupies a mid-elevation growing environment characteristic of many Indonesian tea zones. Estates at this altitude in the Garut region typically experience moderate diurnal temperature variation and high year-round humidity, conditions that tend to support steady vegetative growth. The tropical latitude, approximately 7° south of the equator, generally permits continuous cropping rather than the distinct dormancy periods seen in temperate or high-elevation origins.
Rainfall in the West Java highlands is typically abundant and well distributed, though estates in this zone often see a relative dry season between May and September. The volcanic soils common to the region tend to offer good drainage and mineral availability, factors that can influence leaf development. Mid-elevation sites such as this generally produce leaf at a faster rate than high-altitude gardens, with implications for both yield and flavour intensity.
Tea Produced
Dayeuh Manggung produces both black and green tea. Black teas from mid-elevation Indonesian estates typically yield a straightforward, malty cup with moderate body and relatively low astringency, often suited to blending or everyday consumption. Green teas from this region tend toward a vegetal, grassy character with a light to medium body. The mid-elevation profile generally favours accessibility and consistency over the brisk pungency of high-grown leaf or the aromatic complexity found in some other origins.
Operator
PTPN VIII (Perkebunan Nusantara VIII) is an Indonesian state-owned enterprise managing tea and rubber plantations primarily in West Java. The company operates four other tea estates recorded in commercial directories, making Dayeuh Manggung part of a broader portfolio of production sites within the same administrative structure. State ownership typically entails oversight by central government agricultural policy, though operational and commercial decisions are generally devolved to company management.
Certifications & Ethics
Dayeuh Manggung is certified by the Ethical Tea Partnership, a member-driven initiative that requires participating estates to meet standards on labour rights, health and safety, and environmental stewardship. Certification involves regular third-party auditing against the ETP code, which addresses issues including wages, working hours, freedom of association, and prohibition of child labour. For buyers, ETP membership offers a degree of supply-chain assurance; for workers, it is intended to underpin improved conditions and grievance mechanisms, though outcomes depend on the rigour of implementation and local enforcement.
