All coffee bearing the Sigri name is grown at over 5000 feet elevation. Sigri considers soil and water conservation as a priority, and, the plantation is bird and eco-friendly. The plantation employs a medium density shade strategy, using two types of shade trees. This promotes even ripening of coffee cherries and provides habitat for at least 90 species of birds.

Sigri is a washed Arabica coffee and undergoes a rigorous wet factory process. Quality Control begins in the field; Cherry coffee is 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 selected cherry is then pulped on the day of picking.

A fermentation process follows, a period of three days broken every 24 hours by washing – but unlike most other coffees, the Sigri process follows this by total immersion in water for a further day, which creates a superior coffee. Careful conditioning of 21 days is followed by hulling, grading, color sorting and finally hand sorting. This, combined with rigorous quality control before packing, produces one of the best coffees from Papua New Guinea.

All grades are continuously sample-roasted and cupped both at the estate level and by our quality control team in Chicago. This provides a final check on the green bean quality during processing, before shipment, and upon landing at our US warehouses.
