Kolumbien | Santa Monica Papayo

Paul Bonna opened Kaffeekommune in 2010 as Mainz's first specialty coffee cafe, drawing on experience gained at Hoppenworth and Ploch in Frankfurt before striking out on his own. The roasting operation came later, launching from an old car repair shop that became a dedicated roastery at Lennebergstrasse 1, where all coffee is roasted in house with a focus on activating the natural flavors already present in each bean. A deliberately concise lineup of six single origins, one decaf, and two blends keeps the offering focused, and all roasts follow an omni roast approach suitable for both espresso and filter. Bonna's light roasting philosophy emphasizes sweetness and fruitiness without bitterness, with Ethiopian naturals like the Bombe G1 among the highlights. A wholesale partnership with JB Kaffee allows for custom roast profile development, blending Kaffeekommune's vision with external roasting expertise.
