Mathias Rex is a Budapest-based specialty coffee roaster that's been at it since 1995—a family operation now in its second generation. They run their own roasting facility, sourcing 100% Arabica single origins from across the globe (Burundi, Colombia, Brazil, Costa Rica, and beyond) alongside thoughtful blends. Expect honey-processed gems like the Masasu Honey and well-balanced offerings like Coffee Cartel with its cocoa and citrus notes. They roast to order and ship fast within Hungary. No café—just a family crew who've been dialing in their craft for over 25 years, pulling every lever from green bean selection to the final roast profile.
