ドイトゥンコーヒー
Arabica coffee, mainly the Catimor cultivar, grown in the Doi Tung Development Project area of Chiang Rai Province. It derives from a Thai royal project begun in 1988 as an alternative to opium cultivation, and is registered as a Thai GI (2006) and an EU PGI (2015).

Reading the bitterness
Doi Tung Coffee names coffee grown in the Doi Tung Development Project area of Chiang Rai Province. Japan’s geographical indication (GI) register defines it as arabica, mainly the Catimor cultivar, distinguishing it from robusta, a major coffee species grown in Thailand. The register includes raw beans, roasted beans, and ground coffee. It is therefore treated here as a geographically defined form of coffee from which a beverage can be brewed by roasting the beans and extracting them with hot water. The register does not establish its bitterness intensity or compounds.
The register defines the growing area by coordinates as the Doi Tung Development Project area spanning Mae Fah Luang and Mae Suai districts of Chiang Rai Province: 93,515 rai (about 149.62 square km), 20°07'47"–20°27'17" N and 99°26'31"–99°53'37" E.
After harvest, beans that are less than 80% ripe, insect-damaged, broken, rotten, floating, or blackened are removed visually. The remainder are washed and graded by the washed method at processing facilities designated by the foundation. The register’s history says the growing area stems from the Thai royal Doi Tung Development Project, begun in 1988 to encourage residents to shift from opium poppies to coffee, and that the project received a 2001 award from the United Nations Office on Drugs and Crime for its contribution to drug eradication.
The register states that กาแฟดอยตุง (Kafae Doi Tung) was registered as a Thai geographical indication in 2006 and as an EU protected geographical indication (PGI) in 2015, with protection beginning in Japan in 2023. These are specifications for origin, cultivar, and processing, not measurements of actual taste or bitterness intensity. The consulted materials do not describe bitterness compounds or sensory evaluation of Doi Tung Coffee itself; its specific sensory profile remains unverified for readers.
