How Taiwanese Cloud-Roasted Coffee Delivers Sweet Aftertaste

Ever wonder how some cafés serve coffee that’s smooth, rich, and leaves a sweet aftertaste—without breaking the bank? The secret isn’t just premium beans, but a revolutionary approach to roasting that removes impurities and controls flavor with precision.

The answer lies in Taiwan’s ‘FaBei Coffee’ , which serves coffee with a distinct clean and sweet finish—called 'huigan'—using a unique cloud-roasting system and specially sourced Honduran beans, all while keeping startup costs surprisingly low.

The Cloud-Connected Roaster That Changed Everything

It all started with a chance meeting between a Japanese imperial court roaster and a software engineer named Johnson. Worried that his lifetime of roasting expertise might vanish, the roaster shared his concerns. Johnson, a coffee enthusiast himself, proposed an unconventional solution: embedding roasting logic into chips and connecting the machines to the cloud.

The result was the world’s first fully automated cloud-connected coffee roaster. Headquarters can adjust the roast time and temperature of machines in individual stores in real-time, factoring in local humidity and temperature via the internet. This ensures consistency and precision no matter the location or climate.

Why Most Coffee Beans Carry Hidden Toxins

Most coffee beans are shipped in jute sacks across oceans and stored in fluctuating conditions. Exposure to cold, moisture, heat, and repeated temperature shifts causes the beans to oxidize, leak oils, and foster mold. Over time, this environment allows dangerous mycotoxins like aflatoxin to develop inside the beans—even after washing, drying, and traditional roasting methods. These toxins often remain trapped inside, unless removed with advanced processing.

FaBei’s Secret: Clean Honduran Beans & Smart Roasting

FaBei sources 100% high-altitude Arabica beans from Honduras, grown at 1,250 meters above sea level. The beans are harvested only once a year during Honduras’ dry season (February to April), when the 15-degree day-night temperature swing slows growth and increases trace mineral content. But the real breakthrough is FaBei’s proprietary micro-processing technique that eliminates mold and aflatoxins entirely—something conventional roasting doesn’t achieve.

To protect the beans’ health benefits and natural sweetness, FaBei employs a ‘golden roast’ method. This avoids over-roasting, which can generate peroxides and protein denaturation, compounds linked to caffeine jitters and off-flavors. The result is a cup free of harsh aftertastes, with a naturally sweet, clean finish.

How Much Does It Cost to Open a FaBei Café?

Launching a FaBei franchise requires an initial investment of NT$300,000 (approx. $10,000 USD). The first ten applicants qualify for zero franchise fee. For a typical 10–15 square meter shop, equipment—including an ice maker, grinder, espresso machine, fridge, and interior fit-out—costs between NT$1.5–2 million (around $48,000–$65,000 USD). The estimated payback period is 12 to 18 months. FaBei aims to open 30 locations by the end of the year.

Frequently Asked Questions

What makes FaBei coffee’s aftertaste different from regular coffee?

FaBei coffee achieves a clean, sweet aftertaste—known as huigan—by removing mold and aflatoxins from beans using a proprietary micro-processing method, then applying a golden roast technique that avoids over-roasting. This preserves delicate flavors and avoids the bitterness or jitters often caused by burnt or oxidized beans.

How does the cloud-connected coffee roaster work?

FaBei’s roasting machines are connected to a central system that adjusts roast time and temperature for each location based on real-time local temperature and humidity data. This cloud-based control ensures consistent roast quality across all shops, regardless of climate or environment.

Where do FaBei’s coffee beans come from?

FaBei exclusively uses 100% Arabica beans grown at 1,250 meters in Honduras. The beans are harvested only during the dry season (February to April), when a large day-night temperature variation enhances mineral content and slows maturation, resulting in richer micronutrient profiles.

Is the aflatoxin removal process common in coffee production?

No. Most coffee goes through standard washing and roasting, but these methods often fail to eliminate mycotoxins like aflatoxin that develop during storage in damp or fluctuating conditions. FaBei uses a special micro-processing technique to remove these toxins completely before roasting.

How much does it cost to start a FaBei coffee shop?

The initial franchise fee is NT$300,000, but the first ten applicants get it for free. For a 10–15 sqm store, equipment and fit-out costs range from NT$1.5–2 million (~$48,000–$65,000 USD). The typical return on investment period is 12 to 18 months.
