75% of the coffee-producing countries come from the coffee-producing areas of Papua New Guinea on small farms.

However, it is almost inevitable that the surge in production leads to a decline in quality. Before 1991, the quality of coffee was good, and most of it belonged to open Y and so on. After 1991, the quality gradually declined, and with it the European market was lost. The extra price of coffee such as Y also gradually fell. This is related to the country's policy of "one grade, one price". This policy is not feasible for an industry as volatile as coffee. As a result, poor quality coffee beans damaged the image of high quality standards such as Y coffee, resulting in a backlog.

The government's response is to establish a new level of quality, temporarily suspend the production of coffee such as Y, and no longer implement the policy of "one grade, one price". This allows buyers to price according to quality, which is bound to have an impact on the income of farmers who produce shoddy coffee beans. By 1993, the quality problem had been basically solved. Most regular customers are buying coffee from Papua New Guinea again. Coffee such as Y is now sold at a slightly lower extra price, indicating that its quality has improved.

Although coffee trees grow vigorously in some places, the coffee beans harvested vary from raw to ripe due to the lack of persistence of the growers. AA is rare, and you can usually buy An and AB grades. The main characteristics of grade A coffee are: full granules, light acidity, endless aftertaste in Papua New Guinea (Papua New Guinea), about 75% of coffee products come from small local farms. Many farms reclaim land in the forest, and some are in the depths of the forest, almost isolated from the rest of the world. Coffee in the country is grown on highlands between 1300 and 1800 meters above sea level, so it is of high quality. Although coffee is also grown in some lowlands, the yield is relatively small. Most of the locally grown coffee is grown under natural conditions because of the problems and high costs of transporting fertilizers and pesticides to the farm.

The coffee industry plays an important role in the country's economy. More than 1 million people are directly and indirectly engaged in the industry. The government encourages planting by offering a minimum purchase price. The industry itself is controlled by the Coffee Industry Council (Coffee Industry Board). The commission is located in Goroka, in the eastern part of the island, while exports are handled by private companies.

The frost in 1975 destroyed most coffee crops in Brazil, but stimulated the development of coffee in Papua New Guinea. The Government has implemented a scheme to finance the creation of about 20 hectares of coffee plantations in rural or collective land ownership. This measure has indeed increased the penetration of coffee in the local economy, with an annual output of 1 million bags by 1990.
