N Group’s Manzhongtian Estate Earns Rainforest Alliance Certification

If you’ve ever wondered which Chinese coffee farms meet international sustainability standards, here’s one that just made the grade—and it’s not just any certification. The Manzhongtian Coffee Estate, nestled in Yunnan’s famed coffee-growing region, has officially earned recognition from the globally respected Rainforest Alliance.

In short: The Manzhongtian Coffee Estate has passed the Rainforest Alliance’s on-site audit, becoming one of the few certified coffee farms in China. This means its coffee can now be called a “frog bean,” thanks to the alliance’s iconic frog logo—joining a host of other elite certifications previously achieved by parent company Aini Group.

What Is the Rainforest Alliance and Why Does Certification Matter?

The Rainforest Alliance is a U.S.-based nonprofit founded in 1987, headquartered in New York. It’s one of the most authoritative international environmental certifiers, recognized by the Forest Stewardship Council (FSC). Its mission is to protect ecosystems, wildlife, and farming communities by transforming land use, business practices, and consumer behavior. The alliance works with partners in over 50 countries to promote sustainable resource use and ecological balance.

The Rainforest Alliance certification is globally respected for its strict requirements on environmental protection, social responsibility, and sustainable farming. Farms must meet high benchmarks in biodiversity conservation, soil and water management, reduced chemical use, and fair labor conditions to earn the green frog seal.

About the Manzhongtian Coffee Estate

The Manzhongtian Estate is located in Manzhongtian Village, Bangnong Village Committee, Yixiang Town, Simao District, Pu’er City, Yunnan Province. It sits within the “coffee growing golden belt” of Pu’er, known as China’s coffee capital. The farm is part of the Aini Group’s 30,000-mu (about 2,000 hectares) integrated ranch and coffee plantation.

The estate lies at an average elevation of 1,500 meters. At this altitude, coffee develops slowly, allowing more time to build complex flavors, higher density, and better cup quality. The site is positioned on the shaded side of the mountain, receiving limited direct sunlight—an ideal condition for coffee plants. The farm follows strict organic practices, using composted organic fertilizer supplied by its own pasture system.

In 2012, Jeremy Makeford, a seasoned international cupping expert with 46 years of experience, scored Manzhongtian coffee 81.5 points, comparing its quality favorably to Jamaica’s famous Blue Mountain coffee.

Shade-Grown Coffee and Biodiversity at Manzhongtian

The estate employs true “shade-grown” or rainforest coffee methods. Instead of clearing forests, coffee is planted under existing tree cover. This protects the soil, conserves moisture, and provides a natural habitat—benefiting both coffee plants and wildlife. Manzhongtian has also become a de facto coffee seed gene bank. Since 2009, the Aini Group has introduced 34 premium coffee varieties from global origins, including Caturra, Catuai, Ruiru 11, and Variedad 44. These were trialed using large-bag, double-plant nurseries and rainforest planting techniques—all of which succeeded and are slated for wider cultivation across Yunnan.

Beyond coffee, the estate operates as a year-round ecological ranch. It’s home to diverse flora and fauna, including frequent visits from wild Asian elephants—a nationally protected species in China. The presence of these elephants highlights the area’s intact ecosystem. Notably, on July 11, 2014, 21 wild Asian elephants were spotted wandering through the coffee fields and playing by the nearby Manla River. Later, on January 6, 2015, six elephants returned to feast on corn crops near the estate before leaving peacefully.

The ranch itself is also managed sustainably. Aini Group preserves vegetation zones at different altitudes on hillsides to protect native plants and provide shade for cattle. Pasture species are carefully selected and mixed, combining grasses and legumes to ensure balanced nutrition for livestock, which ultimately supplies organic beef to nearly 20 Aini-owned restaurants.

Why This Certification Matters for Aini Group and the Industry

This Rainforest Alliance certification is the latest in a series of international endorsements for Aini Group, which has previously achieved EU Organic, China Organic, Starbucks CP (Coffee Partners), and Pu’er Origin certifications. For a company that has been in coffee for nearly 30 years, Aini’s focus isn’t on scaling up quantity but perfecting high-quality, traceable coffee from Yunnan.

The group promotes a sustainable “rainforest coffee” model—combining organic practices with ecological stewardship. Their approach aligns with global demand for transparency and environmentally responsible sourcing. This commitment also helped attract Starbucks to partner with Aini in 2012.

"As businesspeople, we must not destroy ecology for profit. Our duty is to protect the environment," said Liu Minghui, Chairman of Aini Group.
