Single Origin Specialty Coffee

PNG Coffee is in many ways untamed and unpredictable. Traditionally grown in gardens, not farms, these small plantations account for 85% of the country’s coffee production and exports – meaning it can be difficult to find a grower who can reliably provide quality beans.

One of the most distinguished arabica grown in PNG.

We operate the single largest coffee plantation in PNG, consisting of around 750 hectares and are washed at two mills: Sigri and Bunum Wo. All coffee bearing the Sigri name is grown at over 5000 feet elevation in the glorious, fertile, volcanic soil of the Waghi Valley in the Western Highlands. Sigri does not use any artificial chemical substances, pesticides or herbicides in the cultivation process. Sustainability and conservation are a top priority for Sigri estates - employing a medium-density shade strategy, using two types of shade trees. This promotes even ripening of the coffee cherries and provides habitat for over 90 beautiful, native bird species.
Quality control begins in the field where cherry beans are hand-picked and carefully checked for uniformity; it must be red and fully ripe, which allows for the correct balance of sugar and acid within the cherry. This cheery is then pulped on the day of picking and begins a rigorous wet factory process. This begins with the fermentation process, a period of three days broken every 24 hours by washing.
Unlike other growers, Sigri process follows this by a total immersion in water for an additional day, creating a superior coffee. Our beans are then sun dried for a minimum of 21 days followed by hulling, grading, colour sorting and finally hand sorting. All grades are then continuously sample-roasted and cupped by experts providing a final quality check.
