Introduction:Although Papua New Guinea (PNG) coffee is not as well-known as that from Central and South America, it has carved out a niche in the specialty coffee scene with its unique highland flavors and rigorous grading system. This article delves into the regional characteristics and grading standards of PNG coffee, focusing on the Paradise Bird washed beans from the Sigri Estate. From altitude and processing methods to brewing recommendations, we’ll give you a comprehensive understanding of this Asian-favored, low-acid, bright coffee.
When it comes to specialty coffee origins, many people immediately think of Central and South America or Africa. However, Papua New Guinea (PNG), located in the southwest Pacific, boasts uniquely flavored coffee beans thanks to its naturally gifted volcanic soil and high-altitude environment. This cultural melting pot, home to over 800 languages, relies on coffee as the main source of income for more than 2 million smallholder farming families in the highlands, supporting the livelihoods of 40% of the country’s population.
In the early days, most PNG coffee came from 18 large plantations, but today 85% of the coffee is grown in farmers’ own “coffee gardens”—small farms ranging from just a few trees to several hundred. Though modest in size, these plots can produce surprising quality. According to the PNG Coffee Industry Corporation, many smallholder coffees are highly sought after in international markets for their distinct flavor profiles, especially washed beans, which are brighter and crisper compared to the common semi-washed beans of Indonesia, making them ideal for Asian consumers who prefer gentler acidity.
The history of coffee in PNG dates back to the late 18th century when Dutch sailors first introduced it. It took root in the Rigo region in 1892, with 180 acres under cultivation by 1908. By 1970, production reached 460,000 bags, and today it steadily exports between 900,000 and 1.2 million bags. Major producing regions are found in the Eastern Highlands, Momase, the New Guinea Islands, and the Southern Province, with the highlands being the core area for specialty coffee due to their terrain and climate.
Coffee estates in PNG are divided into large farms and smallholder models. The former, such as the Sigri Estate in the west, are known for their refined cupping profiles. Unlike the low-acid, full-bodied flavors commonly found in Indonesia, PNG washed beans typically exhibit brighter acidity and more layered complexity, creating a distinctly unique flavor profile. Notable producing regions include the Sigri and Kimel, Arokara estates in the Wahgi Valley of the Eastern Highlands. The Sigri Paradise Bird washed beans, the focus of this article, are among the finest examples.
PNG coffee has a rigorous grading system, primarily based on seven criteria: bean size (Screen Size), defects per kilogram (Total Defects per kg), bean shape, green bean color, green bean aroma, roast condition, and cup quality. Among these, bean size and defect count are key—the grades range from AA (>18 screen size, minimal defects) down to T mixed (the lowest grade).Take the AA-grade Paradise Bird beans from the Sigri Estate as an example.Grown at an altitude of 1600–1800 meters and processed using the washed method, they deliver a balanced flavor profile of caramel, dark cocoa, and almonds, with hints of citrus acidity noticeable at lower temperatures.
The Sigri Estate is located in the Waghi Valley of the Western Highlands, at an altitude of 1600–1800 meters, and features well-drained volcanic soil. Established in 1950, it is one of the pioneers of PNG’s coffee industry. The region enjoys cool weather and abundant rainfall, and with decades of planting and processing experience, Sigri’s coffee beans have earned an excellent reputation in the international market. During the harvest season (April to September), only fully ripe red cherries are handpicked, and daily cupping ensures consistent quality. The estate even employs around 6,000 workers, half of whom live on-site, enjoying benefits such as free clinics and primary schools for their children.
Sigri’s commitment to environmental sustainability is also noteworthy: the estate avoids the use of pesticides and insecticides to protect the soil and water sources, making it a habitat for over 90 species of birds, including PNG’s national bird—the bird of paradise—hence the estate’s name.If you enjoy coffee that is low in acidity, well-balanced, and carries chocolatey notes,the Sigri Paradise Bird washed beans are definitely worth a try.
To brew the Sigri Paradise Bird washed beans, we recommend a water temperature of 88–89°C, a brew ratio of 1:15, using a KONO filter and a medium-fine grind similar to sugar. The specific steps are as follows: start with a 30-second bloom using 30 grams of water, then slowly pour water up to 125 grams in stages with a gentle stream. When the water level drops and is about to expose the coffee bed, continue pouring to reach 225 grams to complete extraction. These parameters highlight its creamy, nutty, and gently fruity acidity layers, delivering a smooth and mellow drinking experience.
