ETHIOPIA GERA ESTATE — ANAEROBIC NATURAL

THE CUP

A refined yet expressive cup from Ethiopia’s Gera Estate. Expect vivid fruit tones and a refined sweetness layered with complex aromatics.

THE PRODUCER

Nestled in the highland forests of Jimma, Gera Estate is one of Ethiopia’s oldest and most respected coffee estates. Grown beneath the canopy of native trees, the coffee thrives in biodiverse, organic conditions that promote both environmental balance and exceptional cup quality. Gera’s commitment to sustainability and social responsibility runs deep—offering education, infrastructure, and fair employment to the surrounding community.

The high altitude estate’s forest-grown system allows cherries to ripen slowly, developing dense sugars and complex acidity. These conditions, combined with Gera’s meticulous agronomy and controlled post-harvest process, consistently produce coffees of clarity and vibrancy.

THE PROCESS

Ripe cherries are selectively hand-picked and placed into sealed, oxygen-restricted fermentation tanks for several days. This anaerobic environment encourages specific microbial activity that heightens fruit intensity and complexity without introducing off-flavors.

After fermentation, the cherries are carefully dried on raised African beds under shade for 15–20 days. Frequent turning ensures uniform drying and prevents over-fermentation. The result is a cup that merges the hallmark clarity of Ethiopian coffee with the lush depth and fruit saturation characteristic of anaerobic processing.

WHY WE LOVE IT

This coffee exemplifies the intersection of tradition and innovation—a meticulously grown and processed lot that pushes Ethiopian coffee’s potential forward. Gera’s dedication to quality, ecology, and community shines through in a cup that’s clean, expressive, and unforgettable.

What is the roast recency?

Onyx recommend brewing with beans that are at least two weeks off roast. All beans are roasted to peak flavour at around 8-12 weeks. We have the option to either purchase standard beans (at least 2 weeks but no longer than 6 weeks off roast), or rested beans (at least 7 weeks off roast, no longer than 12). For peak flavour, if you are looking to use immediately, we recommend purchasing the rested beans. If you are adding to your rotation of beans, we recommend purchasing the standard and allowing the beans to naturally rest and mature whilst you rotate through other beans.
