【BrandCollab】avercasso × Kasasagi Coffee｜Coffee Begins with Sorting

“Bean sorting is tedious, but I never take it lightly.”

— Jin Wan, Owner of Kasasagi Coffee

Every cup of specialty coffee is the result of countless eyes and hands working with dedication. For Kasasagi Coffee, bean sorting is not just a process—it is a spirit and a responsibility.

The Story of Kasasagi Coffee

Kasasagi Coffee was born in Taiwan, with its name inspired by the magpie, a symbol of sharing and joy. The brand insists on using coffee as a bridge that connects people and everyday life, hoping that every cup will bring warmth and a better mood.

Jin Wan once shared:

“For me, coffee is not just a product but a companion in life. Whether it’s the first cup in the morning or a moment of rest in the afternoon, I hope every sip feels sincere.”

This belief has helped Kasasagi Coffee gradually build a reputation in the local community and allowed the brand to stand out with its warmth in the specialty coffee market.

From Manual Sorting to AI Selection

The Challenges of Manual Sorting

In the past, Kasasagi Coffee’s sorting process relied entirely on manual work. Jin Wan and his team had to spend tremendous time and effort inspecting each green bean to remove defects. While this careful work ensured quality, it also came with fatigue and efficiency limitations.

“Long hours of bean sorting not only test vision and concentration but also take away focus from what matters most—flavor design and customer experience.”

—— Jin Wan

The Change with avercasso CS ONE

With the introduction of the avercasso CS ONE AI Green Coffee Sorter, Kasasagi Coffee’s approach to bean sorting was revolutionized. CS ONE uses AI to sort beans at high speed, accurately removing defects while running continuously, acting as a tireless partner for baristas. This allows Jin Wan and his team to dedicate more energy to roasting research, recipe adjustments, and customer engagement.

“With CS ONE, we can focus more on creating flavors and sharing the value of coffee. It guards the front line of quality while we can move further ahead.”

—— Jin Wan

The Shared Spirit of avercasso and Kasasagi Coffee

Behind every good bean lies countless rounds of careful sorting and persistence. This dedication to detail is the shared belief of Kasasagi Coffee and avercasso. For Kasasagi, coffee is not just a drink, but a source of comfort and emotion in everyday life; for avercasso, the CS ONE was created as the best partner to safeguard this spirit of craftsmanship. When human focus and AI efficiency come together, coffee quality is no longer just an ideal but a reality that can be achieved consistently.

What Are Defective Beans?

Defective beans refer to beans that have problems during growth or processing, such as mold, insect damage, cracks, or immaturity. Once roasted, these beans can release unpleasant bitterness, moldy notes, or sourness. Even a small percentage can disrupt the balance of the overall flavor. Removing defective beans is not only a fundamental requirement of specialty coffee but also essential to ensure that every cup remains consistent and clean.

How Does AI Improve Bean Sorting Quality?

The AI bean sorter uses high-speed image recognition technology to detect and remove defective beans with greater precision and speed than manual sorting. It can handle large volumes of beans while avoiding errors caused by human fatigue. This ensures that the selected coffee beans maintain pure flavors and consistent quality, allowing consumers to enjoy the same high-level coffee experience every time.

The Role Division Between Craftsmanship and AI

The role of AI is to safeguard baseline quality, ensuring that all green beans meet standards and avoiding defects from affecting the cup. Meanwhile, artisans focus their energy on the more artistic aspects—designing roasting curves, brewing techniques, and customer interaction. Through this human-AI collaboration, baristas are freed from tedious sorting and can dedicate their passion and expertise to creating coffee experiences that are warmer and more soulful.

Conclusion｜A Promise in Every Cup

Since its founding in 2019, Kasasagi Coffee has upheld the core value of “doing our best even where no one can see.” From removing defective beans to roasting and finally serving, each step carries the joint effort of craftsmanship and AI. True dedication means never compromising, even when unnoticed. This spirit is the shared belief of Kasasagi Coffee and avercasso. When defective beans are removed one by one, every remaining bean becomes a sincere promise to the consumer.
