LeBrew × HB Roasting Competition | Hangzhou Station
Abstract
In October 2025, Hangzhou, China hosted a remarkable event where professionalism and passion intertwined — the iQube Coffee Roasting Exchange Competition (East China Division, Hangzhou Station).
Organized by HB Roasters at their Hangzhou Experience Center, the competition gathered roasters, specialty coffee shop owners, and experts from across the country.
As the Official Roast Colorimeter Sponsor, LeBrew provided advanced analytical instruments that offered precise and reliable roasting data, enhancing the scientific rigor of the competition and giving participants a more visualized, data-driven roasting experience.
Technology Empowering Roasting: LeBrew RoastSee Series on Stage
During the competition, LeBrew presented two of its latest innovations — RoastSee NEXT and RoastSee Fusion — which quickly became highlights of the event.
-
RoastSee NEXT – Real-Time Color Change & First Crack Analyzer
-
RoastSee Fusion – All-in-One Coffee Analyzer
Renowned for their high precision, rapid measurement, and exceptional stability, the RoastSee Series provided accurate color references, helping competitors scientifically evaluate roast development and bean color consistency.
On-site, the LeBrew team demonstrated RoastSee NEXT in real time — showcasing Agtron readings, yellowing point markers, first-crack detection, and post-roast analysis.
This groundbreaking approach transformed sensory intuition into measurable data, allowing roasters to achieve consistency and precision like never before.
Where Passion Meets Professionalism: Every Moment Captured
At the competition, the LeBrew team acted not only as technical supporters but also as storytellers — capturing passionate moments of craftsmanship and focus.
📸 From contestants adjusting machines and observing bean color changes,
to using RoastSee Fusion and RoastSee NEXT, and judges cupping with intensity — every frame reflected the relentless pursuit of perfection.
-
Competitors used RoastSee Fusion to measure the water activity of green beans.
-
They also measured the color value of ground coffee for record and comparison.
-
On trial day, roasters experienced RoastSee NEXT for the first time, exploring real-time roasting analysis.
At the post-roast testing area, LeBrew instruments became the roasters’ most trusted “second pair of eyes.”
With RoastSee Fusion, participants measured bean color, moisture, density, and water activity, correlating these data with roast curves to fine-tune their flavor profiles.
Competition judges commented:
“With such precise tools, roasters can make better adjustments during trial sessions and ensure their final competition roasts reach optimal performance.”
This embodies LeBrew’s mission —
Technology for Flavor Precision.
Innovative Collaboration: Advancing Standardization in Roasting
The partnership between LeBrew and HB Roasters represents more than sponsorship — it’s a shared vision for standardizing and digitalizing coffee roasting.
Together, the two brands are exploring data integration between color metrics and roast curves, aiming to connect RoastSee NEXT’s real-time data with HB Roaster temperature profiles.
This integration could enable automatic recognition of key roasting points such as yellowing and first crack, paving the way for smart, data-driven roasting systems.
This innovation marks a key step toward a future of intelligent, stable, and precise coffee roasting, aligning perfectly with LeBrew’s 2025 core philosophy:
Empowering every coffee creator through science and innovation.
Let Technology Extend the Passion for Coffee
From competition stages to laboratories, from pour-over bars to roasting stations — LeBrew believes that technology is not about cold data, but about helping coffee lovers create their best work.
We sincerely thank HB Roasters and the iQube Competition Committee for their trust and support — and every roaster who tested, discussed, and shared their feedback with us.
Moving forward, LeBrew will continue to appear at more coffee competitions and professional events, providing roasters worldwide with precise, intelligent, and data-driven instruments to explore every shade of color and every nuance of flavor.
