“Coffee is my way of being honest with the world.” — Jin Wan, Owner of Kasasagi Coffee

Quality in Every Cup, Detail by Detail

At Kasasagi Coffee, every bean selected and every roasting temperature controlled reflects the persistence that owner Jin Wan wants to deliver. He believes that coffee is not just a drink but the most honest companion in life.

The Story of Kasasagi Coffee: Sincerity in the Details

The name Kasasagi Coffee comes from the magpie, symbolizing sharing and joy. Since its founding, Jin Wan has regarded coffee as a life philosophy: building connections through sincere flavors, one cup at a time. He often says: “Even if customers cannot see it, we must still perfect every detail.” It is this spirit of craftsmanship that has helped Kasasagi Coffee gain a reputation in the specialty coffee scene, becoming a trusted choice for many coffee lovers.

The Challenge of Bean Sorting: The Limits of Manual Work

Before adopting AI technology, Kasasagi Coffee relied entirely on manual sorting. Each barista had to spend hours under bright light, carefully inspecting beans to remove moldy, insect-damaged, or immature defects. While this dedication protected quality, it also left the team exhausted. Jin Wan admitted: “Even the sharpest eyes can miss defective beans—this is our daily reality.”

The limitations of manual sorting lie not only in efficiency but also in accuracy. Even just 1–2% of defective beans can disrupt the balance of flavor. This challenge has long troubled Kasasagi Coffee.

The Turning Point: Discovering avercasso CS One

Everything changed when Jin Wan encountered the avercasso CS One AI Green Coffee Sorter. Using 4K imaging and AI recognition, CS One quickly removes SCA-defined primary and secondary defects with up to 99% accuracy. For Jin Wan, this was more than saving time and effort—it was peace of mind: “It feels like a steady, reliable pair of hands helping me perfect every detail.”

Compared with manual sorting, CS One processes far more beans in less time while maintaining consistent standards and avoiding errors caused by fatigue. For Kasasagi Coffee, sorting is no longer dependent solely on human judgment but backed by a scientific, replicable system of quality control.

Human-AI Collaboration: Making Sincerity Visible

Kasasagi Coffee chose to entrust “pickiness” to avercasso not to cut corners or replace artisans, but to ensure that no detail escapes scrutiny. AI serves as the guardian of baseline quality, allowing baristas to focus on the more heartfelt aspects—roasting curves, flavor design, and customer experience.

“The same raw material can create different value. If sincerity is a kind of warmth, then avercasso is the pair of hands that carries that warmth farther and steadier.” — Jin Wan

Why Are Details the Soul of Coffee Quality?

Coffee flavor is built upon countless details. Even a single defective bean can release bitterness or moldy notes after roasting, disrupting the entire balance. For Kasasagi Coffee, these seemingly small details are the true key to quality. Only by rigorously selecting green beans and removing every defect can a cup showcase pure complexity, allowing customers to truly feel the spirit of craftsmanship.

How Does AI Let Artisans Focus on What Matters Most?

Manual sorting demands hours of exhausting work and still risks oversight. With CS One, AI can complete large-scale sorting quickly while maintaining high precision and consistency. The time and energy saved let baristas devote themselves to designing roast curves, exploring flavors, and engaging with customers. By handling tedious work, AI allows artisans to focus their expertise on creating value.

What New Value Does Human-AI Collaboration Bring?

AI plays the role of a reliable gatekeeper, working steadily through long hours to prevent errors caused by human fatigue, ensuring the basic quality of beans. Artisans, meanwhile, channel their energy into flavor design and expressive craft—through roasting, brewing, and sharing with customers. When technology and humanity work side by side, coffee is not only delicious but also carries emotion and sincerity, creating even greater value.

Conclusion｜A Cup Worth Treating with Care

The collaboration between Kasasagi Coffee and avercasso is not merely a case of adopting technology, but a shared commitment to quality and sincerity from the source to the cup. With CS One’s intelligent coffee sorting technology, the tedious manual process has been simplified while maintaining the highest standards. Sorting becomes easier without losing professionalism or dedication, ensuring flavors remain pure and vibrant. When you enjoy a cup at Kasasagi Coffee, you taste not only flavor but also a promise jointly upheld by “craftsmanship + AI technology.”
