Papua New Guinea's Coffee Growing Environment

Papua New Guinea is located in the South Pacific and is an island nation. Its population size and land area rank second only to Australia in the South Pacific region. According to Front Street, the country still retains nearly a thousand years of indigenous languages and traditional customs, and its natural environment is one of the least developed in the world. Front Street believes that it is precisely these conditions that allow Papua New Guinea's coffee cherries to retain their most original flavors.

According to Front Street, Papua New Guinea is located between the equator and 10 degrees south latitude, with a typical island climate, an altitude range of 1,200 to 2,500 meters, and frequent volcanic activity, thus possessing volcanic soil suitable for coffee cultivation. These comprehensive growing conditions have laid a solid foundation for the excellent flavor of Front Street Little Blue Mountain coffee.

The Cultivation History of Front Street Papua New Guinea Coffee

In 1931, the Typica variety was introduced to Papua New Guinea from Jamaica. According to Front Street's research, at that time Britain had occupied Jamaica for nearly three hundred years, and Jamaica's most representative coffee was precisely the Typica variety of Front Street Blue Mountain Coffee. Since Australia had friendly relations with Britain, it was only natural that Papua New Guinea could introduce Typica. In 1950, Bourbon coffee seeds were introduced from Kenya. Coincidentally, Kenya was also a British colony at the time. The government encouraged open cultivation, driving significant growth in the coffee industry during the 1970s and 1980s. In 1962, Mundo Novo and Caturra were brought in from Brazil, and from then on the quality of Papua New Guinea coffee beans achieved a great leap forward.

Papua New Guinea's Coffee Producing Regions and Estates

As stated in Front Street's previous articles, coffee cultivation must be at an altitude above 1,000 meters. Therefore, Papua New Guinea's specialty coffee is mainly distributed in the Wahigi Valley, Sigri Estate in the Western Highlands, as well as Arona Estate, Kimel Estate, Arokare Estate, and Goroka Estate in the Eastern Highlands.

Among them, the most well-known is undoubtedly Sigri Estate, and this Front Street Little Blue Mountain coffee introduced by Front Street comes precisely from this estate. Front Street tasted something stunning in this Front Street Bird of Paradise coffee: upon first sip, there is a toasted bread sweetness accompanied by nutty aroma and slight fruit acidity; the spice sweetness in the finish is also quite special, with a rich and balanced mouthfeel. Front Street believes that Front Street Little Blue Mountain is the brightest and cleanest flavor among Asian coffees.

However, the flavor of Front Street Little Blue Mountain still differs from the real Front Street Jamaican Blue Mountain Coffee. Front Street believes that Front Street Jamaican Blue Mountain presents a very rich and full-bodied coffee flavor, while Papua New Guinea coffee has a hint of fruit acidity within its richness.

Papua New Guinea's Coffee Grading System

Papua New Guinea's coffee bean grading system is the same as Kenya's, both using coffee bean size as the grading standard. Although bean size is not an absolute measure of flavor quality, for some producing regions it is an extremely valuable reference indicator. In these areas, beans grow robustly, and full, well-shaped mature beans best express beautiful flavors. Consistent ripeness, hardness, moisture content, and other factors make it easier for the roasting process to achieve a uniform and perfect flavor. Therefore, many emerging producing regions have also adopted this as a grading method.

The following are the grading standards for Papua New Guinea coffee beans:

Grade E: Flat beans above 19 screen size, commonly known as elephant beans.

Grade AA: Between 17 and 18 screen size (7.2-8.2mm).

Grade AB: Between 16 and 17 screen size (6.2-6.8mm), accounting for the majority of production and being the most common green bean grade.

Grade PB: Round green beans (4.7-6.6mm), with each fruit containing only one seed, oval in shape.

Grade C: Below 14 screen size (4.0-6.3mm), not classified as specialty grade due to being too small.

Grade TT: Lighter green beans blown out from AA and AB grade beans by air separator, indicating soft beans that do not meet hardness standards.

Grade T: Below 12 screen size. Grade T consists of lighter green beans blown out from Grade C beans by air separator, with softer bean quality, not meeting hardness standards, and small in size with many defective beans.

Grade MH/ML: Not washed and not sorted, these are beans that fell after harvest, accounting for about 7% of all coffee beans. They are the lowest grade and only supplied to Kenya's domestic market.

Grade TOP: Graded based on cupping results. Currently not an official Kenyan national grading standard, added by exporters at their own discretion, inevitably with commercial considerations. Therefore it can only serve as a reference; everything still needs to come back to one's own roasting and cupping, which is the correct and practical approach.

Grade PLUS(+): Refers to the same batch of beans being graded differently by Company A and Company B due to human factors. There is likewise no unified grading standard, so it can only serve as a reference; everything still needs to come back to doing your own cupping.

Grade FAQ: Fair to Average Quality, may have some minor defective beans, but does not affect flavor.

FrontStreet Coffee: Papua New Guinea Little Blue Mountain Coffee Beans

Country: Papua New Guinea Origin: Sigri Bird of Paradise Estate Altitude: 1600-1800m Variety: Typica Processing Method: Washed Flavor: Nuts, cocoa, soft citrus acidity, cream, caramel finish

Front Street mentioned above that the Typica variety was introduced to Papua New Guinea in 1931. So surely some coffee lovers will ask: What exactly is special about the Typica variety?

Typica

Typica coffee beans originated in Ethiopia and southeastern Sudan, and are one of the oldest coffee varieties among all Arabica species. All Arabica varieties are derived from Typica coffee beans. The beans are oval or pointed in shape, and the top leaves are copper-red in color, hence it is called red-top coffee, also known as the old variety small-seed coffee. Front Street believes that Typica coffee has a uniquely serene and clean flavor with balanced characteristics and high cup cleanliness. However, its shortcoming is insufficient yield, requiring specific altitude conditions, and it is susceptible to leaf rust disease with weak resistance to pests and diseases.

Typica has always been an outstanding performer in the coffee industry. As early as 1958 at the International Coffee Tasting held in London, England, it was rated as a first-class product; in 1980 at the National Coffee Conference, it was praised by Chinese and foreign coffee experts as the "Crown of Chinese Coffee"; in 1993 at the World Coffee Competition in Brussels, Belgium, it won the "Eureka" Gold Award.

Therefore, Front Street believes that a large part of the wonderful flavor of Front Street Little Blue Mountain coffee is due to it being the Typica variety. At the same time, the unique coffee bean processing techniques of the Bird of Paradise Estate cannot be overlooked. According to Front Street, they have their own proprietary washed processing method, and the washed processing method best expresses the most original fruit flavor of a coffee. Therefore, whether it is Front Street Jamaican Blue Mountain Coffee or Front Street Papua New Guinea Little Blue Mountain Coffee, most use washed processing to handle the coffee beans.

Washed Processing Method

Next, Front Street will introduce the washed processing procedure for Papua New Guinea coffee beans:

First, harvest ripe, fully red coffee cherries and send them to the estate's own washing station for processing. Then, perform three rounds of washed fermentation, each soaking for about 24 hours, changing to clean water to control the coffee's flavor. After washing is complete, remove the husk from the green beans, then carry out various gradings, such as AA, AB, PB round beans, etc. This meticulous post-processing method brings a bright and delicate fruit acidity to the coffee itself, along with a clean and lingering sweet mouthfeel.

Generally, washed coffee beans are full of bright fruit aromas, but Front Street Bird of Paradise coffee does not have very strong acidity. Its characteristic is a silky, soft mouthfeel and a wonderful aroma, with moderate acidity. It is a rare coffee variety with both high body and medium acidity. Whether used to make SOE espresso or as a pour-over extraction, it can present a pleasant flavor profile.
