42 Coffee is a Budapest roaster with proper third-wave roots. Founder Nezvál Máté grew up around coffee — his father brought Faema to Hungary — and after tasting specialty at the World Barista Championship he went all in, opening what's often called Hungary's first open roastery. The beans come straight from farmers or a single middleman, fair-trade style, from the top slice of the world's specialty crop. A decade on, 42 supplies a lot of Budapest's better coffee shops and runs its own barista school. If you want single origin specialty coffee with a real story behind the roast, start here.
