The core Bonanza offering: coffee brewed fresh to order through a precise pour-over method. They typically feature five rotating single-origin roasts that change with the season — Ethiopian washed, Colombian natural process, Rwanda, and more. The light roast emphasizes origin characteristics without any char. At 3 euros for a standard cup, it's straightforward specialty coffee. The focus is on flavor clarity and the unique qualities of each origin.
Tips from diners
Ask the barista about the current single-origins — they'll explain where each bean comes from and its tasting profile.
Bonanza pioneered this approach before pour-overs became Instagram rituals. The philosophy is honest and the execution is precise.
While Bonanza focuses on filter coffee, their espresso is equally thoughtful. Light-roasted to avoid masking the bean's characteristics, it's meant to be pulled with precision. Ask the barista which roast is currently in the machine — it changes with the season.
Tips from diners
If you prefer espresso to pour-over, Bonanza's is worth trying — different approach than you might expect.
For those who prefer milk-based coffee, Bonanza makes a thoughtful cappuccino using their seasonal espresso roast. The milk is steamed with care to create a silky microfoam. It's a more indulgent option than the pour-over but still rooted in coffee quality.
Tips from diners
A solid cappuccino if you want milk — not as adventurous as the pour-over, but well-made.
One of Bonanza's best-kept secrets: for 5 euros, you can order a refillable cup and pour multiple filter coffee origins throughout your visit. It's designed as a tasting experience — try an Ethiopian, then a Colombian, then a Rwandan, all within one café session. The baristas embrace this and will help you understand how origin and processing method affect flavor. It's excellent value and a genuine way to experience specialty coffee.
Tips from diners
The 5-euro refillable cup is the best specialty coffee value in Berlin — do this instead of a single espresso.
Spend an hour with the refillable cup, talking to the barista about each origin. You'll taste how much variety exists in specialty coffee.
Bonanza sells their roasted beans by the kilogram or pre-packaged. Prices range from around 6.50 euros for entry-level origins to 17.29 euros for premium lots. They provide detailed tasting notes and brewing guibalance. This is specialty coffee meant to be brewed at home with precision — grinders, scales, and brewing equipment are also available for purchase.
Tips from diners
Buy beans to take home — the café sells equipment (grinders, scales) and provides brewing guides with each purchase.
Bonanza Coffee Roasters opened in 2006, pioneering the specialty coffee movement in Berlin before it became mainstream. The philosophy is simple: honor the bean and trust the process. They roast light to emphasize terroir and origins, with no char or over-roasted masking flavors. The team personally visits farms in growing countries to check quality and pay fair prices. Bonanza opened their flagship roastery café in Kreuzberg with a minimalist interior, outdoor seating, and a refillable cup program that celebrates coffee as a tasting experience.
Open 9am weekdays, 10am weekends. Monday-Friday 9am-6pm, Saturday-Sunday 10am-6pm. Less crowded mid-afternoon (2-4pm) if you want quiet time.
The café has a communal table with power outlets and free WiFi — friendly space for working, but don't monopolize seating during peak morning rush.
The baristas are knowledgeable and passionate — ask questions about origins, processing, brewing technique. They'll engage with your curiosity.
