Case Study: How KIMMIK Reinvented Green Bean Sorting with avercasso

About KIMMIK｜Creating Everyday Magic with Passion

At first glance, KIMMIK might seem like just another ordinary coffee shop. But behind it lies a deep passion for quality and flavor, founded by a self-proclaimed coffee geek and a curious flavor explorer. They aim to express their love for quality through coffee and bakery creations.

The core mission of KIMMIK is simple: “To create affordable ‘wow' moments for customers every single day.” That’s why every menu item is designed to be simple and approachable, encouraging people to come back again and again. But behind this simplicity lies meticulous planning, careful execution, and obsessive attention to detail.

The Challenge: Becoming True Specialty Coffee & the Burden of Manual Sorting

As KIMMIK expanded its journey into coffee roasting, they stuck to their principles, refining through trial and error to develop a repeatable, sustainable roasting process. Through this process, they realized just how critical manual green bean sorting is to ensuring flavor quality, because even one defective bean could ruin the flavor profile of an entire roast.

Being detail-oriented by nature, the team manually sorted every batch before roasting, carefully removing as many defects as possible. But this process typically required at least 3 to 4 consecutive hours, a huge time investment that became harder to maintain as their business continued to grow.

Searching for a Solution: From Image Recognition to avercasso

To break through the bottleneck of manual sorting, KIMMIK began exploring automation. They needed a solution that could match the accuracy of hand-sorting while being easy to operate and maintain.

They explored traditional color sorters, which offered great throughput and efficiency, but consistently fell short of the precision needed for specialty coffee. In SCA, the definition of a “defective bean” is strict and unforgiving.

During one internal discussion, they recalled a case where AI image recognition was used to grade cucumbers, and began wondering if this technology could also be applied to green coffee beans. That’s when they discovered avercasso®, and it felt like the perfect fit.

Real Experience: Accuracy, Consistency, and True Impact

KIMMIK has now been using the avercasso CS One for several months, and the overall experience has been excellent.

Setup, operation, and daily maintenance were all easy to handle, but the most impressive part was the sorting accuracy. After conducting several comparison tests between machine and hand sorting, they found the results remarkably similar. With the right module, avercasso matched the precision of human sorting and removed defects at a comparable rate.

In fact, in some cases, the machine outperformed humans, for example, in identifying insect damage at the tips of beans, where the AI often proved more reliable than the human eye.

The consistency and repeatability of results were also standout features. The machine delivered uniform sorting results across batches and freed up valuable team time that could be spent on other business operations. It was a massive improvement in overall efficiency.

Key Strengths & Wishlist for the Future

KIMMIK is highly satisfied with avercasso’s performance, especially in terms of precision and consistency.

Looking ahead, they hope to see a feature that allows users to train their own AI modules. This would allow roasters to customize sorting sensitivity based on their needs or even create specialized modules for unique processing methods. Such a feature could open up a new level of personalization and control for professionals in the specialty coffee space.
