Yunnan BM Coffee Beans: The Local Blue Mountain Variety

If you’ve ever wondered whether China grows coffee that can rival classic origins like Jamaica’s Blue Mountain, the answer might already be in your cup—or at least growing in Yunnan. The so-called BM variety, widely believed to be a local adaptation of the famed Jamaican Blue Mountain, is cultivated at elevations between 1500 and 2000 metres in Simao and Baoshan. But does it really deliver a balanced, high-quality cup? Here’s what makes these beans stand out.

Yes, Yunnan BM coffee beans are considered among the top-tier varieties grown in China. Planted at 1500–2000m altitude, processed via washed method with clean, minimal defects, and known for a hard bean texture—these beans surprised tasters in 2006 by producing a bright, clean, and well-balanced cup even from a basic moka pot.

What Is the BM Coffee Variety?

The BM variety found in Yunnan is commonly understood to be a lineage derived from the Jamaican Blue Mountain coffee plant. Though not officially certified as Blue Mountain, these beans are grown at similar altitudes and have been cultivated in Yunnan’s Simao and Baoshan regions. The name “BM” is widely taken to refer to this Blue Mountain heritage, though it is not an officially recognised protected designation.

Growing Conditions and Processing

Yunnan BM coffee is grown at elevations between 1500 and 2000 metres—conditions that mirror some aspects of the high-altitude environments famous for producing balanced, nuanced coffees. The beans are processed using the washed method, which results in clean, bright flavours. According to the source, post-processing the silver skin is removed thoroughly, and the defect rate is very low. The beans are also noted for their hard bean (HB) density, a physical trait often associated with slower maturation and better cup quality at altitude.

Unexpected Cup Quality from Basic Brewing

In a 2006 coffee tasting event in Shenzhen, participants were surprised by the cup quality of Yunnan BM coffee. Using an ordinary moka pot—the kind of brewer often criticised for producing overly bitter or harsh results—brewers achieved a cup that was described as bright, pure, rich, and balanced. Notably, there was no unpleasant bitterness typically associated with high-heat moka brewing. More than ten attendees reported surprise and enjoyment, challenging assumptions about the capabilities of Chinese-grown coffee. Even a respected Japanese home roaster and author, in his book Coffee Encyclopedia (page 102), gave high praise to Yunnan coffee.
