NATURAL MOSSTO — GAYO, ACEH

Mossto is a term borrowed from the world of winemaking. In coffee, mossto refers to the liquid released during coffee cherry fermentation, rich in sugars, organic acids, yeast, and active bacteria.

Rather than being discarded, this liquid is reintroduced into the next batch as a starter culture, much like winemakers use must. Wild fermentation becomes guided fermentation, which is why mossto profiles tend to be fuller, sweeter, and more clearly defined.

This lot is Natural Mossto from Nosar, Bener Meriah, grown at an altitude of 1,400–1,600 meters above sea level, using Bourbon and Ateng Super varieties.

Our potential notes point toward lychee tea, mango, and black tea—the kind of flavor profile people often seek in imported coffees, yet rarely expect to find in coffee from Aceh.

For home roasters who have grown tired of conventional natural processing, this specialty green bean offers an opportunity to explore and understand the impact of fermentation.

Aceh, beyond the familiar. Fermentation, with a different dimension.

Lychee Tea | Mango | Black Tea

We call them potential notes, not tasting notes. These are green beans, not roasted coffee. What ends up in the cup depends on your roasting profile. We simply provide a starting point.

EVERY LOT IS QUALITY-CHECKED >>

Origin, grade, processing method, moisture, density, and defect count.

We inspect, store, and document every lot. Coffee is not magic. Coffee is a process, and processes can be tested.

TRIPLE-PICK QUALITY ASSURANCE

Why Is Our Green Bean Quality More Transparent?

Most marketplace sellers claim Grade 1 quality based on a single pass through a coarse mechanical sorting machine.

At Coffest Roastery, we implement three stages of physical sorting and refinement:

1. Suton Machine

Removes foreign materials such as stones, twigs, dust, broken beans, and residual husks that make it through earlier processing stages.

2. Optical Sorting Machine (SORTEX)

Uses modern optical sensor technology to eject black beans, sour beans, and beans with defects caused by insect damage.

3. Hand Sorting (Manual Pick)

Our expert team performs the final manual inspection to remove fungus-damaged beans and bring the defect count as close to zero as possible.

Drying is carried out using indirect sunlight through a greenhouse-effect technique to preserve optimal flavor potential.
