The coffee flavor of Papua New Guinea is very different from that of other Asian regions such as Indonesia, South Asia, India or the Pacific Islands. compared with Indonesian beans (Sumatra, Sulawesi) which are mostly semi-washed (wet peeling), they show low acidity, mellow texture and soil conditioning.

Papua New Guinea, to the east of Indonesia, has a standard island climate, located between the equator and 10 poisonous latitudes, with tropical rain forest volcanic rocks and plateau topography, between 1200 and 2500 meters above sea level, making it a paradise for growing coffee. The local yield is small, and about 85% of the total coffee is produced by the garden cultivation system of small farmers. Small farmers join local cooperatives and share their processing equipment. Coffee is Pakistan's second largest export of agricultural products, which shows the importance of coffee industry to Pakistan's economy. Because the variety of coffee is different from that of Indonesia, and the altitude is higher than Sumatra, coupled with the use of water washing treatment, the regional taste of PNG coffee is different from Indonesia's muggy and low flavor, but has bright, sweet and sour, flower and fruit aromas, similar to the flavor of South America.
