How Passion Powers a Specialty Coffee Roastery Business

Ever wonder how some coffee shops and online stores sell beans you actually want to buy again—and others don’t? For coffee lovers hunting reliable, well-roasted beans with real flavor, it’s frustrating to sort through endless options online. One shop that gets it right—and teaches you why—started small, with two passionate roasters who refused shortcuts.

To consistently sell quality coffee, you need more than beans: you need expertise, equipment, selection discipline, and customer trust. That’s exactly what Taiwanese founders Jiang Chengzhe and Zhang Jinming built into their brand, Oubake , since 2011. And they teach it too.

Who Is Oubake and Why Does It Matter?

Oubake is a specialty coffee roastery based in Shanghai, selling freshly roasted beans through Taobao. But it’s far from just another online coffee seller. Founded in May 2011 by two Taiwan-born coffee professionals, Oubake also runs offline classes on roasting, brewing, and cupping. Their mission: help others understand and make better coffee, not just sell product.

The founders, Jiang Chengzhe and Zhang Jinming, are certified SCA cuppers and former competition winners. Jiang took first place in the 2013 TCRC (Taiwan Coffee Roasting Championship) and second in the World Cup Tasters Championship. Zhang was the 2012 Taiwan Cup Tasters Championship runner-up. Both are deeply knowledgeable and hands-on.

Their workspace, located in the suburbs of Shanghai, is part classroom, part roastery. There are small tables, professional gear, music playing, and, always, the smell of coffee. Whiteboards explain coffee concepts—visual aids used in their regular workshops.

What Makes Oubake’s Coffee ‘Specialty’?

Oubake defines ‘specialty coffee’ strictly by industry standards. According to the SCA, green beans must have fewer than 5 defects in 350g to qualify. Most commercial beans fail this test. To meet the mark, Oubake hand-sorts both raw and roasted beans. Only those scoring 80+ points in cupping tests make the final cut.

Jiang explains that defect sorting isn’t just about cleanliness—it impacts flavor. “When you taste a great cup, it’s the result of dozens of careful steps,” he says. “Good coffee requires discipline at every stage.”

To hit that sweet spot between sour and bitter, Oubake aims for balanced sweetness and clarity. They reject the idea that even roast color equals quality. Instead, they developed a proprietary roast method called Coreshell. This technique creates a contrast between the core and outer layer of the bean—enhancing sweetness, body, and aroma complexity.

Roasting takes place on Mondays and Thursdays. On those days, the roastery runs at full capacity. Two roasting machines—one large, one small—work through orders placed before 10am. The team typically roasts about 500 pounds of coffee per month, a volume limited by staff and time. To maintain quality, Oubake is reducing the number of bean offerings.

How Did Oubake Build Trust Online Without Paid Ads?

Oubake gained its early customers entirely through organic interest. Founder Jiang Chengzhe posted in coffee forums and relied on word-of-mouth. He credits the shop’s professional presentation and transparent expertise for winning trust. “We didn’t spend on ads. People came because we showed what real specialty coffee looks like,” he says.

The brand’s visual identity, detailed product descriptions, and curated selection signaled seriousness. Prices range from ¥49 to ¥289 per half-pound, with most offerings priced affordably. “I want coffee to be for everyone,” Jiang says, “but that doesn’t mean lowering quality.”

The most popular offerings include fresh single origins and carefully chosen blends. Every batch is roasted to highlight origin character while maintaining balance and drinkability.

What’s the Role of Education in Oubake’s Model?

Education is central to Oubake’s mission. Since 2011, the founders have taught brewing, cupping, and roasting techniques in hands-on workshops. These aren’t marketing stunts—they’re practical, technical, and focused on real skills. Topics include proper blooming times (which vary by bean), roast profiles, and brew methods like pour-over.

By 2024, Oubake had partnered with over 50 cafés across China, supplying them with beans and knowledge. Many clients started as students. “People couldn’t find trustworthy training,” Jiang says. “There’s a lot of misinformation—for example, the idea that blooming must always take 30 seconds. That’s not true. It depends on the beans.”

Oubake uses scientific tools to demonstrate extraction principles. Jiang studied abroad to refine his understanding and even created his own roasting style, which intrigues international peers. The goal isn’t to create competitors, but to grow the market responsibly.

“Some ask to collaborate on cafés. We might offer technical support while others handle operations,” Jiang adds. He’s also considered launching a specialty coffee information hub, inspired by years consulting with Yunnan coffee farmers and hosting cupping sessions for local producers.
