Bio Espresso

Roestbar is a specialty coffee roaster based in Münster, Germany, running multiple cafés across the city alongside their own roastery, pastry shop, and a coffee school that offers SCA-certified courses. They've been at it for over two decades—founders Mario and Sandra recently looked back on 22 years of building this coffee culture over a 'Kaffeeklatsch' chat. The current lineup leans toward single-origin offerings from Kenya, Rwanda, Colombia, Ethiopia, and El Salvador, with a washed Ruanda and a Pink Bourbon Colombia catching the eye. They're not just roasting; they're teaching the next generation of baristas through masterclasses and courses. Six café locations around Münster or order beans through their shop.
