The Origins of Taiwan’s Gukeng Coffee

If you’ve ever wondered where Taiwan’s best-known specialty coffee comes from—and why it’s called “imperial coffee” or linked to a mysterious latitude—you’re not alone. Most coffee lovers outside Taiwan have never heard of Gukeng, yet this small region produces a rare, sweet, and smooth Arabicabean with a uniquely local profile. So how did this coffee earn global praise and a royal past?

Gukeng coffee, grown in Hualien District, Yunlin County, Taiwan, is a rare high-quality Arabicabean praised for its sweet, aromatic, and non-bitter cup profile. First introduced during Japanese colonial rule, it flourished in the early 20th century with up to 113 hectares under cultivation. Today, Gukeng is known as the 'homeland of Taiwanese coffee' and uses '23.5' as a brand to guarantee authenticity.

What Is Gukeng Coffee?

Gukeng coffee originates from the Hualien area of Gukeng Township in Yunlin County, Taiwan—located right on the Tropic of Cancer. The region enjoys abundant sunlight and rainfall, creating ideal conditions for cultivating Arabicabean. The resulting coffee is noted for being sweet, rich in aroma, low in bitterness, and distinctly reflective of Taiwan’s terroir. It’s considered among the finest single-origin coffees produced in Taiwan.

The History of Coffee in Taiwan

Coffee was first introduced to Taiwan by the Dutch in 1624, but it remained limited to Dutch settlers and didn’t gain widespread cultivation. Later, during Japanese colonial rule in 1931 (Japanese Showa 6), a man named Kimura began large-scale coffee planting in what is now northern Tainan, including parts of modern-day Chiayi and Gukeng in Yunlin.

By 1941 (Showa 16), coffee production peaked, with most beans shipped to Japan. The Hua Shan region of Gukeng, particularly around He Bao Shan , hosted 75 hectares of coffee plantations. At that time, Gukeng had one of the largest coffee processing facilities in East Asia, earning the nickname 'Far East’s Largest Coffee Factory.'

After World War II in 1945 (Showa 20), the coffee area briefly expanded to 113 hectares, but falling crop prices led to abandonment or repurposing of fields. It wasn’t until 2000 (Republic of China Year 89) that local government initiatives reignited interest, prompting farmers to replant and market Gukeng coffee again.

In 2003 (ROC Year 92), Yunlin County Government hosted the first Taiwan Coffee Festival at the Janfusun Fancyworld amusement park, inviting veteran coffee farmer Huang Gengzi. By 2006 (ROC Year 95), Gukeng’s Hualien area had around 100 hectares under coffee cultivation, producing over 10,000 kilograms of beans annually.

Why Is Gukeng Coffee Called ‘Imperial Coffee’?

During Japanese rule, the Taiwan Governor-General’s Office imported coffee beans from Brazil and tested them in several locations: Taitung, Hualien’s Ruisui, Kaohsiung, Gukeng in Yunlin, and Huisun Forest Farm in Nantou. Gukeng’s beans were judged the best, and during the imperial period, they were presented as a tribute to the Japanese Emperor. This association earned Gukeng coffee the prestigious nickname 'imperial coffee' or 'royal coffee.'

The 23.5 Brand: Protecting Gukeng’s Identity

Because of its limited production and high reputation, Gukeng coffee has often been counterfeited by other brands selling non-Gukeng beans as ‘Gukeng.’ To combat this, local producers adopted the brand name '23.5,' referring to Gukeng’s location near the 23.5°N latitude—the Tropic of Cancer. This branding helps assure consumers they are purchasing authentic Gukeng-grown Arabicabean.
