【BrandCollab】avercasso × Kasasagi Coffee｜Every Single Bean Matters

“The quality of coffee can be seen from a single bean.” — Jin Wan, Owner of Kasasagi Coffee

Specialty coffee worth savoring is built on details that can never be overlooked.

Sometimes, just one unnoticed defective bean is enough to alter the entire flavor of a cup of coffee.

Kasasagi Coffee’s Craftsmanship: Care in Every Detail

Jin Wan often says:
“Great flavors are never accidental; they exist because we refuse to compromise on every single detail.”

From green bean selection to roasting and brewing, Kasasagi Coffee has always upheld the principle of “doing our best even when customers cannot see.” This spirit of craftsmanship has allowed the brand to build unique warmth and trust within the specialty coffee market.

avercasso CS One: The AI Partner That Safeguards Details

The Blind Spots of Manual Sorting

Traditional manual sorting requires long hours of concentration under strong lights, yet the human eye inevitably misses defects. These defective beans release off-flavors or bitterness after roasting, undermining the balance of the cup.

AI Technology to Fill in the Gaps

avercasso CS One AI Green Coffee Sorter is equipped with advanced AI image recognition technology that identifies and removes SCA-defined primary and secondary defects with up to 99% accuracy. Users simply select the coffee’s processing method (e.g., natural or washed), and the system automatically completes the sorting process, significantly reducing labor and human error.

Jin Wan shared:
“CS One helps us safeguard the details that the naked eye can easily overlook. It feels like a partner that never compromises, giving us confidence to focus more on flavor performance.”

More Innovative Services

avercasso is more than just an AI bean sorter—it’s a complete solution designed for coffee professionals. Through the equipment sharing system (avercasso Points), even without owning a CS One, baristas can purchase sorting points and use the machines at designated sharing sites. Points are only deducted for successfully selected premium beans, making it efficient and cost-effective. The system also comes with built-in natural and washed AI modules, with optional add-ons such as anaerobic fermentation, honey process, and wet-hulling modules—all with free updates. This flexibility allows roasters to adapt to different origins and processing methods, enabling true customization. In addition, CS One provides intuitive green bean quality analysis reports to help producers and roasters continuously improve bean sourcing, ensuring every cup remains consistent and pure in flavor.

Dedication Unseen Creates Quality That Can Be Seen

True dedication means never compromising, even when no one is watching—a belief shared by both Kasasagi Coffee and avercasso. Since even a single defective bean can ruin the flavor profile, AI technology has become a crucial partner in protecting the details. With automation, it greatly improves sorting accuracy while reducing human oversight. Moreover, through the sharing economy system, even those without equipment can access CS One’s professional services, ensuring every cup of coffee is delivered with stable quality.

Why Do Details Impact Coffee Quality?

Coffee flavors are extremely sensitive. Even with just 1–2% defective beans, roasting and brewing can release unpleasant bitterness, moldy notes, or sourness that overwhelm delicate flavors. These seemingly small details ultimately determine the balance and stability of a cup. For artisans, removing defective beans is not optional—it is the most basic and vital step in quality assurance.

How Does AI Sorting Reduce Human Error?

Manual sorting requires prolonged focus, but changes in lighting and visual fatigue easily lead to errors and missed defects. The CS One AI Green Coffee Sorter maintains consistent precision over long periods, using 4K image recognition to inspect each bean and accurately detect even the smallest insect holes or mold spots. Compared to humans, AI works faster and avoids discrepancies caused by fatigue or subjective judgment, making quality control more reliable and consistent.

The Value of Sharing and Modular Services

avercasso is more than a sorting machine—it empowers professionals of all scales with equal access to quality assurance through shared facilities and modular AI services. With avercasso Points, users without their own machines can access professional equipment at shared sites, lowering entry costs. Additionally, roasters can purchase AI recognition modules for specific processes such as anaerobic fermentation or honey, with continuous free updates. This flexibility allows small studios, large roasters, and even estates to secure quality in ways that best fit their needs, helping push the entire industry forward.

Conclusion｜The Original Purpose Behind Every Cup

Kasasagi Coffee chose to collaborate with avercasso not only to improve efficiency but because they believe that quality lies in every detail. In the past, manual sorting required long hours under bright lights, yet fatigue still caused defects to be overlooked. Even traditional color sorters, while efficient, struggled to meet the precision required by specialty coffee. Today, with avercasso’s intelligent coffee bean sorting technology, AI can sort large volumes quickly, automatically removing moldy, insect-damaged, or immature beans to leave only the best. Each carefully preserved bean represents the combined persistence of artisanship and AI consistency. This human-machine partnership not only safeguards flavor consistency but ensures that quality is delivered in every cup—a sincere promise from Kasasagi Coffee to its customers.
