Thai/Vietnam
As the producer of Robusta, Vietnam is the second biggest global supplier and producer of coffee. In general, Robusta is grown in Africa and Asia (India, Indonesia, Vietnam) at altitudes of 600 meters. The growing of this type of coffee is simplest because it is resistant to tropical heat and parasites, and it grows at lower altitudes, and thus it has lower production and sale price. It grows in harsh environment such as rainforests, where, for example, Arabica would fail to resist diseases such as “coffee rust”.
