Flavour Creation through Fermentation


Project Raggiana is about creating flavour, building relationships and sharing the story of coffee and coffee people from the Wahgi Valley and the Sigri Estate in Papua New Guinea.

The project is our ticket to discovering PNG coffee and people, exploring the flavour implications of low-oxygen fermentation and capturing a story we could share with the folks back home.

Processing at the Sigri Estate


Through controlled and innovative processing methods we were able to create a selection of microlots from the one lot. Each method adopted was thoroughly researched, then designed to affect the flavour – creating a unique story for every cup brewed in Zest Cafes.


Zest headed to PNG endeavouring to develop a sustainable working relationship with the people of Sigiri Estate. In future, we will be nurturing this relationship with further projects that will improve the quality and flavour of the beans they produce. This in turn will provide a sustainable lifestyle for the Sigri People.


The story of origin and its coffee people is both beautiful and compelling. Our aim was to capture and present that story within a format that both resonates and engages our desired audience.

Robert. A curious 9 year old.


This is Robert from Sigri. He’s 9 years old and lives in a hut made out of woven ferns deep within the jungle on the edge of the Wahgi River in the Western Highlands of Papua New Guinea.


Although we were unable to directly speak to each other, it amazes me how much can be said through simple gestures and basic hand actions.

He became my little camera assistant for the day, although was absolutely terrified of the menacing appearance of the drone flying overhead. After a few minutes I was able to show him the screen, what his house and world looked like from the sky, leaving him with an ear to ear smile that wouldn’t leave his face. Several hours later, an entourage of his friends arrived, and he was in his element. He was explaining to them in pigdgin what was inside the big black box, how it has propellers and flies through the sky with its own set of eyes and a face, and how it watches down from above. He described all of this was via actions and hand movements to a crowd of inspired faces.

Up until now, most of these kids had never even seen a picture of themselves until observing their portraits on the back of my camera. This was one of those moments that I know will stay with me forever.

The Women who work the coffee.

The women at Sigri are full of joy and always asking to have their picture taken. They are completely uninhibited, they smile and dance and play. They are the spirit of PNG culture.


The fruit of our travail.

Sooner rather than later, the 6 lots we processed will be available for order. Keep in mind these are only experiments, so quantities are very low and we will run out of them really quickly.


Stay tuned for these micro-lots being available. We're expecting them to arrive at Zest around the middle of July.
