Case Study No. 18

Korgua Peaberry, Papua New Guinea

Coffees from Papua New Guinea have a special place in my heart because sometimes they taste like this one. In the roaster it’s a really sensitive coffee, which makes it an interesting challenge to get the profile just right. It’s a balancing act of getting just the right amount of heat, not too much and not too little, at just the right times during the roast. But when you hit the sweet spot, this coffee really sings. 

In the cup, it’s sweet, tropical, and juicy like ripe pineapple, mango, and grapefruit with a gentle and pleasantly balanced acidity. It finishes clean with a lingering savoury note of something like basil. Overall, it’s fruity and vibrant but at the same time creamy and smooth. 

This coffee comes to us from a single estate called Korgua, located in the Tambul-Nebilyer district of Papua New Guinea. Brian Leahy, who manages the Korgua plantation, also manages a local coffee processing mill called Kuta, so he is able to be hands-on to ensure quality at every from harvest to processing to export.

This particular lot is a peaberry outturn, which means that it’s made up of only the coffee cherries that are affected by a genetic mutation that produces a single seed in the cherry instead of the usual two. This happens in something like 5% of coffee cherries, and, in a peaberry lot like this, they can sometimes produce a different flavour profile from the typical coffee grown in the same field. In addition to being delicious, peaberries also happen to be adorable.

I hope you enjoy this coffee as much as I do.
