Hainan Xinglong Coffee: What Makes It Unique?

If you’ve ever wondered why some of China’s most distinctive coffee comes from a tropical island better known for beaches than beans, the story of Hainan’s Xinglong coffee holds surprising answers. Grown in lowland conditions far from traditional coffee regions, Xinglong defied the odds—and still brews a bold cup today.

Xinglong coffee is a dark-roasted, full-bodied brew made almost exclusively from Robusta canephora, specifically the medium-sized variety well-suited to Hainan’s humid, low-altitude environment. Its signature rich, slightly sweet taste with a hint of saltiness comes from a traditional roasting method that includes butter, sugar, and salt.

The Origins of Xinglong Coffee

Xinglong coffee was first planted in 1953 in Hainan’s Xinglong region, then part of a newly established overseas Chinese farming community. The goal was 'using short-term crops to support long-term ones'—coffee, along with lemongrass and rice, was introduced to offset the slower returns of rubber plantations. The first coffees came from Chengmai’s Fushan area.

Early trials showed that while large-bean Arabicas were high-yielding, they lacked flavor, and small-bean Arabicas couldn’t thrive in Hainan’s sea-level heat. Eventually, Robusta canephora—specifically the medium-sized variety—was selected as the most viable option. The region’s latitude, climate, and elevation provided ideal conditions for this hardier, more productive coffee type.

How Xinglong Coffee Is Roasted and Blended

Xinglong coffee is famous for its intense, aromatic roast style, influenced by Southeast Asian techniques. The beans are roasted in large drum roasters for 15–20 minutes at temperatures between 177–240°C, until they reach a color matching the standard sample. They are then quickly cooled, ground, and sealed.

To enhance flavor, roasters add specific ingredients during the roast: per 12.5 kg (de-hulled) of beans, they mix in 0.15 kg salt, 0.25 kg egg white, 0.5 kg butter, and 2.5–4.5 kg sugar. The process involves multiple stages: starting with high heat, adding salt after the beans turn brown, then egg white, butter, and finally sugar, which is stirred in until fully dissolved. The roast finishes over a low flame or charcoal until the beans are uniformly dark, with a slightly rough texture and visible sugar adherence. Total roasting time per batch is around 2.5 hours.

Traditional Techniques and Cultural Impact

The roasting method, which includes adding butter, sugar, and salt, creates a cup that’s bold, creamy, and slightly sweet—traits reminiscent of Turkish or Indonesian-style coffees. This technique likely originated from Indonesian traditions, where similar additions are common. Some roasters even roast in large batches onsite at tourist spots, allowing visitors to witness the process and taste freshly brewed cups.

Despite its unique profile and cultural roots, Xinglong coffee has struggled to gain widespread recognition. Once cultivated on over 3,000 acres, the coffee acreage has shrunk to less than 1,000 due to falling market prices since the 1990s. Yet, for many locals, drinking Xinglong coffee remains a daily ritual, reflecting a deeply rooted coffee culture that persists outside the mainstream.

In 1960, then-Premier Zhou Enlai visited Xinglong and praised the local coffee, famously saying it surpassed many foreign varieties. That endorsement helped build its reputation, but broader success has remained elusive.

Growing Conditions and Geographic Protections

Xinglong coffee is protected under China’s geographical indication system. The official protection zone covers Xinglong Overseas Chinese Farm and surrounding areas in Wanning City, including Nanqiao, Changfeng, Niulong, Sangengluo, and Liji towns.

The coffee is grown at elevations below 900 meters, typically in shaded, humid valley areas near forests. Farms often include windbreaks. Ideal soils are well-drained, fertile red or yellow loams with a pH between 4.5 and 6.5. Key soil nutrients must exceed: hydrolyzable nitrogen (60 mg/kg), available phosphorus (15 mg/kg), available potassium (80 mg/kg), and organic matter (25 g/kg). Sandy loam and alluvial soils are also acceptable.

How Xinglong Coffee Is Processed

The roasting process requires constant attention. Roasters must:

• Ventilate continuously to remove the seed coat and prevent scorching, which can cause bitterness.
• Adjust heat carefully—starting with high heat, then switching to low once sugar is added to avoid burning and off-flavors.
• Cool beans quickly before grinding to prevent moisture absorption and clumping. Grind to a coarse consistency suitable for brewing, not a fine powder.
• Seal the final product immediately to preserve aroma and flavor.

These traditional techniques are not suited for other Arabica varieties.
