We’re beyond excited to share that Mikaël Portannier, freshly crowned World Coffee Roasting Champion 2025, is officially joining us as our Ambassador for Shop Roasters.
If you’ve been following this year’s World Coffee Roasting Championship in Houston, you’ll know Mikaël impressed judges and fellow competitors with his precision, creativity, and respect for coffee. Representing France, he walked away with the title of best roaster in the world.
We’ve always believed shop roasting is where the heart of specialty coffee lives. It’s where community, creativity, and craft come together in small batches that make a big impact. Mikaël embodies that same spirit, and now he’s bringing his championship skills and personality to you.
As our Shop Roaster Ambassador, Mikaël will:
Share his knowledge with the community; think roast approaches, insights, and lessons learned from the world stage.
Highlight the potential of shop roasters and how they can be tools for both consistency and creativity.
Connect with roasters worldwide through events, workshops, and digital content to inspire both new and experienced professionals.
Mikaël’s style fits perfectly with Giesen’s philosophy: giving roasters the freedom and precision to get the best out of every coffee. Together, we want to keep pushing what’s possible with Giesen roasters and help more coffee professionals turn their ideas into reality.
Expect to see Mikaël at industry events, featured in Giesen content, and connecting directly with roasters across the specialty scene. He’s as passionate about sharing knowledge as he is about finding the perfect roast profile, and we can’t wait to see the collaborations that will come.
