Yunnan small-grain coffee is a distinctive mutated variety that evolved through long-term cultivation and domestication of Arabica coffee in Yunnan, boasting a planting history of over a hundred years. This variety is mostly grown in dry-hot river valley areas at an altitude of around 1,100 meters, resulting in a unique profile with gentle acidity, rich aroma, and a smooth mouthfeel.

From a geographical and climatic perspective, southern Yunnan enjoys abundant sunshine, facilitating sufficient photosynthesis for coffee plants. Coupled with significant diurnal temperature variations, the cool nights help accumulate nutrients within the coffee cherries, often giving Yunnan small-grain coffee superior performance in both nutritional content and flavor compounds compared to many other regions.

Local cultivation techniques and per-unit yields are also among the global leaders. In recent years, international coffee brands such as Nestlé, Starbucks, and Maxwell have successively established raw material production bases in Yunnan, further boosting the international visibility of “Yunnan Coffee.”

The ideal planting altitude range for small-grain coffee is generally between 800 and 1,800 meters.
