Bonanza Coffee Roasters is one of the true pioneers of European specialty coffee, founded in Berlin in 2006 by Kiduk Reus and Yumi Choi. They were among the very first to introduce meticulously sourced and transparently roasted specialty coffee to the German capital — long before the third wave hit Berlin's mainstream. Their philosophy of being "unnecessarily good" shows in every cup: clean, expressive roast profiles designed to highlight sweetness and clarity. Named Best Independent Coffee Shop in Europe at the 2025 European Coffee & Hospitality Awards, Bonanza now operates multiple cafés in Berlin and has expanded to Seoul. They ship fresh seasonal beans across Europe for home brewers, cafés, and wholesale partners worldwide.
