Green Bean l Gayo Natural Anaerobic 1kg
Fermentation occurs in coffee whether you control it or not. What sets anaerobic processing apart is the level of control. The coffee cherries are placed in a sealed container without oxygen, changing the types of microorganisms at work. Carbon dioxide builds up, helping regulate the process and allowing fermentation to proceed more slowly.
The result is not simply a more intense flavor profile, but one that can be reproduced more consistently from batch to batch. That consistency matters when you want to feature the coffee as a permanent item on your menu.
This lot is a Natural Anaerobic coffee from Nosar, Bener Meriah, grown at an altitude of 1,400–1,600 meters above sea level and featuring the Ateng Super variety. Our assessment points toward mango, jackfruit, and chocolate.
For coffee shops looking for a coffee that makes customers stop and ask, “What coffee is this?”, these Gayo Anaerobic green beans are one of the strongest candidates in our specialty lineup.

POTENTIAL NOTES
Mango | Jackfruit | Chocolate
We write potential notes, not tasting notes. This is green coffee, not roasted coffee. What ultimately ends up in the cup depends on your roasting profile. We simply provide a starting point.
EVERY LOT GOES THROUGH QUALITY CONTROL
Origin, grade, processing method, moisture content, density, and defect count. We inspect, store, and record every lot.
Coffee is not magic. Coffee is a process, and processes can be tested.
TRIPLE PICK QUALITY ASSURANCE
Why Is Our Green Bean More Reliably Sorted?
Most marketplace sellers claim Grade 1 quality based on just one round of coarse machine sorting. At Coffest Roastery, we apply three stages of physical purification:
1 // Suton Machine
Filters out foreign objects such as stones, twigs, dust, broken beans, and silverskin that may have passed through from earlier processing stages.
2 // Optical Sorting Machine (SORTEX)
Uses modern optical sensor technology to eject black beans, sour beans, and beans damaged by insect bites.
3 // Hand Sorting (Manual Picking)
Our expert team performs the final manual inspection to remove fungus-damaged beans and ensure that defects are reduced to nearly zero.
The drying process uses indirect sunlight through a greenhouse system to help preserve the coffee’s optimal flavor characteristics.
