Arabica is grown on plantations in Northern Thailand,
mainly in the following provinces:
Chiang Mai, Chiang Rai, Lampang, Mae Hong Son and Tak.
Arabica trees thrive at higher altitudes, which in Thailand
is between 800 to 1,500 meters. In these altitudes,
the beans mature at a slower pace, producing generally
a richer, denser, more flavorful bean. Arabica in Thailand
is still in a kind of experimental stage, which helps
explain its low yearly harvest. Most Thai Arabica coffee
is grown by small holders, such as hill tribe families
and villages, as well as in research stations (Wawi,
Chang Khian, etc.) and development programs. The few
hundred tons of beans that are annually picked are brought
almost entirely by local traders and roasting factories
for producing roast and ground coffee.
