Koji Fermented Specialty Coffee from Chikkamagaluru | Koji Fermentation Process Coffee

Fine Robusta, reimagined through fermentation science and origin craftsmanship.

Koji’s Fine Robusta is a fermented specialty coffee from Chikkamagaluru, India, developed to push the boundaries of what Robusta can be. Through controlled Koji fermentation (Aspergillus oryzae processing) and precision roasting, this lot transforms Fine Robusta into a vibrant, fruit-forward, and structurally complex coffee experience.

At Wonderbean Coffee Co., we focus on origin-first innovation. This experimental lot, crafted at St. Margaret Estate by Lynn Mascarenhas, represents a new frontier in specialty Indian coffee processing—where microbiology meets terroir.

Origin Story – Specialty Fine Robusta from Chikkamagaluru

Chikkamagaluru is globally known for its high-altitude coffee estates and ideal microclimate for specialty cultivation. Traditionally, Robusta from India is associated with strength and intensity.

Koji’s Fine Robusta changes that narrative.

Using Koji fermentation coffee processing techniques, we unlock hidden sugar pathways and aromatic complexity within the bean. The result is a cup that is not just bold—but layered, expressive, and refined.

This is not an imitation of Arabica.
This is Fine Robusta elevated through fermentation innovation.

Koji Fermentation Process – Experimental Coffee Processing Method

Koji’s is processed using Aspergillus oryzae, a traditional fermentation culture used in Japanese food science.

Under controlled anaerobic conditions:

Koji enzymes break down complex sugars and proteins in the coffee cherry
Natural fructose conversion enhances fruit-driven flavour compounds
Aromatic precursors develop into new volatile complexity
The bean absorbs deeper enzymatic sweetness and clarity

This results in a fermented coffee profile that is clean, juicy, and structurally balanced, while retaining Robusta’s natural body and caffeine strength.

Roast Profile (Roast Scale)

Roast Level: Medium Roast

Roast Scale	Level
Light Roast	Not used (to preserve fermentation structure)
Medium Roast	✔ Primary roast level
Medium-Dark	Avoided (to maintain fruit clarity)
Dark Roast	Not applied

We choose a medium roast profile to preserve fermentation-derived aromatics while enhancing sweetness, body, and structure. This ensures maximum expression of Koji fermentation complexity without roast domination.
