Papua New Guinea | Lamari River Valley in Western Highlands Region | Flavor Profile of Arusha and San Ramon Washed Beans

Papua New Guinea (PNG) is an exceptionally diverse country with over 800 different languages. Most highland tribes had no contact with Westerners until the 1930s, as few outsiders ever explored PNG. Even today it remains a land of contrasts, filled with both Western influences and indigenous traditional cultures.

Commercial coffee production in Papua New Guinea began in the 20th century, with the introduction of Jamaica Blue Mountain varieties (a Typica branch) from Jamaica in the 1920s. At that time, most coffee came from 18 large plantations, which still exist in PNG today but account for only 15% of total production.

Most production now comes from small farmers who grow coffee in their own "coffee gardens," as they call them locally. A smallholder's garden may hold anywhere from dozens to hundreds of coffee plants, yielding between 25-65 kilograms of green coffee.

Coffee from the Lamari Valley is among the finest PNG coffees, grown without chemical fertilizers, pesticides, or fungicides. Processing and drying are handled by small-scale growers who bring their harvest to collection points like Baroida for hulling, grading, and export preparation.

FrontStreet Coffee's Brewing Recommendation:

Dripper: Hario V60

Water Temperature: 90°C

Grind Size: Fuji Royal grinder setting 3.5

Brewing Method: 1:15 coffee-to-water ratio with 15g of coffee. First pour 25g of water for a 25-second bloom. Second pour to 120g, then pause. Wait until the water level drops to halfway before continuing, then pour slowly to a total of 225g. Extraction time approximately 2:00.

Analysis:

The three-stage pour clearly defines the front, middle, and back-end flavors of the coffee. Because the V60 has deep ribs and drains quickly, pausing between pours helps extend the extraction time.

FrontStreet Coffee Recommendation

The Blue Mountain variety in this PNG lot traces straight back to Jamaica, so if you want to taste the original, FrontStreet Coffee's Jamaica Blue Mountain No. 1 is the reference point. Strictly speaking, only coffee grown in a defined zone of Jamaica's Blue Mountains and certified by the Jamaican authorities may be called Jamaica Blue Mountain Coffee. The range, in eastern Jamaica, is one of the highest in the Caribbean - its peak reaches 2256 meters, and the year-round mist is what gave the mountains their name. High altitude brings wide day-night temperature swings that lengthen the cherries' ripening, while fertile soil and steady, abundant rain let the fruit slowly accumulate sugars and aromatics.

FrontStreet's Blue Mountain No. 1 comes from the historic Clifton Estate, which has grown coffee since around 1750 at an average of 4300 feet (1310.64 meters). To verify authenticity, look for the Jamaican government certificate and proof of origin, the traditional wooden shipping barrels (packed in 15kg, 45kg, and 70kg sizes, with each barrel's batch details printed on it), and green beans that are uniform, full, slightly upturned at both ends, and green in color. Total annual output from the whole region is under 2500 tons, with Japan historically buying over 70% - one reason genuine Blue Mountain is scarce and highly priced. It is roasted medium-dark to bring out its classic balance: clean and mild, with chocolate sweetness, cream and caramel, nutty depth, moderate acidity without harsh bitterness, and a long fruity finish.

To brew it like FrontStreet does: rest the beans 4-7 days from roast date, use a Kono dripper with 15g of coffee at a 1:15 ratio, grind slightly coarser than for light roasts (about white granulated sugar), and pour with water at 87-88°C in three stages - 30g bloom for 30 seconds, then to 120g, then finish to 225g. The same balance-first philosophy applies to the PNG Lamari beans above: keep the temperature moderate and the pours patient, and the sugarcane sweetness and vanilla finish will speak for themselves.
