Brussels was buzzing last week with the energy of World of Coffee (WOC) – three days of conversations, tastings, and discoveries about what makes great coffee at Europe’s largest specialty coffee trade show. At the Fermentis booth, we connected with producers, roasters, scientists, and industry leaders to advance the role of controlled fermentation in coffee quality.
Why Fermentation Matters for Coffee Producers
Fermentation has always been part of coffee processing, but its role in shaping flavor is only now being fully understood. For many producers, it remains an unpredictable step – one that can make the difference between a remarkable cup and a missed opportunity. That’s why our experts were on hand: to talk about how small changes in fermentation can lead to more consistent, expressive coffees.
At our booth, we demonstrated how SafCoffee™ yeast strains – Sunrise Orange, Cool Blue, Green Origins, and Deep Amber – can help producers enhance aroma, stabilize quality, and create unique flavor profiles. We served samples of the same Colombian Arabica variety, processed four different ways – each with a different SafCoffee™ yeast strain. The differences were subtle but clear, a reminder that controlled fermentation isn’t just about avoiding defects; it’s about guiding the coffee toward its best possible expression.
Producers stopped by over the three days, curious about how these methods might work on their own farms. Some had questions about consistency; others wanted to know how fermentation could help them highlight the unique qualities of their terroir. What stood out most were the conversations with growers who had spent years chasing quality, only to see it fluctuate from harvest to harvest. They weren’t looking for quick fixes – they wanted to understand the process better, to gain more control over something that had always felt a little mysterious.
Our team also spoke with researchers studying indigenous yeast strains, with roasters interested in how fermentation affects roast profiles, and with producers experimenting with new processing methods.
Key Takeaway from WOC 2026
Fermentation is the Next Frontier in Coffee Quality!
The coffee industry is evolving, and producers are increasingly recognizing that fermentation is not just a processing step – it’s a science to be mastered. When done right, it can elevate a good coffee to an exceptional one, ensuring consistency year after year. This allows coffee farmers to differentiate their beans, command premium prices, and move beyond commodity markets.
Today, fermentation is quickly becoming less of a hidden step and more of a deliberate craft. Our team left Brussels with new questions, new connections, and a deeper appreciation for the complexity of coffee. We can’t wait to continue these conversations and connect with more passionate industry professionals next year at WOC 2027!
