Yunnan BM Coffee: The Blue Mountain-Type Bean

Ever wondered if there’s a credible Blue Mountain-type coffee grown outside Jamaica? Many have asked whether China—specifically Yunnan—produces beans that can rival the world-famous Jamaican Blue Mountain. The answer lies in a lesser-known variety in Yunnan: the BM type.

The BM-type coffee bean, said to be introduced from Jamaica, is grown at elevations between 1,500 and 2,000 meters in Yunnan’s Simao and Baoshan regions. With clean washing processing, uniform bean shape, minimal defects, and hard bean texture, it’s one of Yunnan’s highest-grade offerings.

What Is the BM-Type Coffee Bean?

The BM-type coffee bean is commonly understood as a variety brought to Yunnan from Jamaica, possibly related to the original Blue Mountain cultivar. Grown primarily in Simao and Baoshan, these beans are cultivated at altitudes of 1,500 to 2,000 meters—within the optimal range for high-quality Arabica. While not officially certified as Jamaican Blue Mountain, the BM type is considered among the finest coffee varieties produced in China.

Processing and Physical Characteristics

These beans undergo a washed processing method, resulting in exceptionally clean silver skin removal and a very low percentage of defects. The beans are noted for their uniform size and hard physical structure, both indicators of high processing quality and good cup potential. The consistent bean shape and careful processing are key reasons why roasters and cuppers take notice.

Flavor Performance and Brewing Results

When roasted, the BM-type coffee does not exhibit the slight acidity often found in typical Bourbon varieties. During a coffee gathering in Shenzhen on June 24, 2006, even a basic moka pot produced a cup that was bright, clean, rich, and well-balanced—with none of the bitterness usually associated with overly hot moka extractions. Over ten participants reported surprise and enjoyment at the cup quality. This performance suggests that the BM type, when handled properly, can deliver a smooth and balanced cup rivaling more famous origins.

Recognition in Specialty Coffee Literature

The quality of Yunnan-grown coffee, including the BM type, has earned recognition beyond China. For example, the Japanese specialty coffee book Coffee Encyclopedia, on page 102, praises Yunnan coffee for its favorable attributes. Such endorsements from global experts help validate the cup potential of this lesser-known origin.
