From Kreuzberg Kitchen to Berlin Institution: How One Entrepreneur Built a €2.3m Coffee Empire

On a corner of Kottbusser Damm where the U-Bahn rumbles beneath Art Deco facades, Mira Hassan is roasting coffee beans at precisely 198 degrees Celsius. It's a specificity that matters. For the past eight years, her roastery—Brennerei Friedrichshain, though based solidly in Kreuzberg—has become the kind of Berlin business that outsiders find perplexing and locals fiercely protect.

"People thought I was mad," Hassan recalls of her 2018 decision to lease the former metalworking workshop on the corner of Mehringdamm. The neighbourhood was different then: fewer tourists, more vacancy signs. Today, her operation processes over 120 tonnes of green coffee annually, supplying roughly 200 cafés across Berlin and beyond. By her own conservative estimates, the business now turns over €2.3 million annually—a figure that would have seemed impossible when she started with a single vintage Italian roaster and a €40,000 bank loan.

Hassan's trajectory reflects a broader shift in Berlin's entrepreneurial ecosystem. Unlike the venture-backed tech startups clustering around Mitte and Charlottenburg, her model relies on something increasingly rare: patience and product obsession. She sources directly from smallholder farmers in Ethiopia and Colombia, pays 40 percent above commodity prices, and spends roughly one-fifth of her operational costs on quality control.

"The coffee industry had become industrialised," she explains. "Berlin's café culture was exploding, but most roasters were just buying pre-roasted commodity stock from international distributors." Her timing proved impeccable. The explosion of third-wave coffee consciousness across the city meant her €28-per-kilogram single-origin Ethiopian natural process became currency among a growing demographic willing to pay.

The numbers are compelling. Since 2018, her café count has grown from three accounts to two hundred. Wholesale pricing begins at €18 per kilogram, but her direct-to-consumer channel—from a small tasting room tucked beneath the roastery—commands prices that would have seemed absurd a decade ago. Her signature cold brew sells for €4.50 per 200ml glass, yet the roastery moves roughly 300 glasses weekly.

What separates Hassan's operation from countless other artisanal ventures is consistency across scaling. Quality hasn't fractured as volume increased. Her team of twelve trained roasters follow protocols that would satisfy specialty coffee certifiers internationally, yet her warehouse remains unmistakably Kreuzberg: concrete floors, exposed brick, an aesthetic that feels earned rather than designed.

As Berlin's reputation for authenticity faces pressure from homogenisation, Hassan's success suggests something crucial: that the city's business future belongs not to those chasing international capital, but to those patient enough to build something worth actually consuming.
