Bonanza is one of Berlin's landmark roasters, going since 2006 and quietly influential across Europe's specialty scene. Their tagline says it best — 'not your typical specialty coffee; it's unnecessarily good' — and the roasting backs it up, chasing clarity, sweetness and expression rather than anything heavy-handed. They run four cafés around Berlin (Mitte, Friedrichshain, Prenzlauer Berg and more), so there's plenty of chances to taste it on home turf, and they ship fresh, seasonal beans across Europe with a subscription if you want it on repeat. If you want clean, precise, genuinely benchmark-setting single origin specialty coffee, Bonanza is a must-try.
