KOSU Koffiebranderij

Suikerlaan 20, Groningen, Netherlands

KOSU is a specialty coffee roastery based on the Suikerterrein in Groningen. They roast everything on site, fresh and local, and source their beans either directly from farmers or through small scale importers. No middlemen doing shady stuff, just carefully picked coffee. It's not just a shop though. You can grab bags of their current roasts, pick up gear like Moccamasters and Chemex filters, or go deeper with their workshops. They run a barista school that's been around since 2017, covering everything from basic barista skills to latte art and sensory training. There's even a roastery tour if you want to see where the magic happens. The people behind it clearly care about the whole chain. They invest in regenerative agriculture, the beans are grown naturally without pesticides, and they've got a blog with stories from the farms they work with. It's the kind of place where coffee isn't just a product, it's the whole point.
