01 Coffee origins in Yunnan
Into the mountains where Yunnan coffee grows.
Coffee fields spread across the slopes, with red fruit peeking through green leaves.
In Yunnan, southwest China, these are the landscapes where a cup of coffee begins.
Follow the paths through the fields and discover the work of the people who grow and harvest the fruit.

02 Explore the origins
Yunnan's coffee regions, nestled in the mountains.
Yunnan lies in southwest China, bordering Myanmar, Laos and Vietnam. Mountains and rivers create a varied landscape, with elevation and climate changing from place to place. Coffee is grown mainly in the west and southwest of the province.
Pu'er is one of the main origins. Farms are scattered through the hills of Simao, Menglian and other areas, on slopes and in open valleys. Even within Pu'er, sunlight, temperature and rainfall vary with each farm's location.
In western Yunnan's Baoshan, the Lujiang Valley along the Nu River at the foot of the Gaoligong Mountains is a well-known growing area. Arabica has long been cultivated in this warm, sunny valley. In Dehong, which borders Myanmar, coffee is also grown around Mangshi and Ruili, alongside research and development of locally suited varieties.
Behind the name “Yunnan” are these differences between places. Which mountain and which farm grew the coffee? Knowing a little more about its origin adds another pleasure to choosing your everyday cup.
03 Into the fields
Look between the leaves and discover the coffee cherries.
From a distance, a coffee field looks like a sea of green. Walk closer along a path and you will see small fruits among the glossy leaves: some still green, some changing colour and others ripe and red. Even on one branch, the fruit develops at different rates.
The “small-grain coffee” grown in Yunnan is Arabica. Arabica includes many varieties, each with its own characteristics. In Yunnan, varieties and growing practices are selected to suit local temperature, rainfall and altitude.
After white flowers bloom, the coffee tree develops small green fruits. They gradually grow, and varieties that ripen red bring bright colour between the leaves as harvest approaches. Because the ripe fruit resembles a cherry, it is called a coffee cherry.
The coffee beans we usually see are the seeds inside the fruit. A cherry typically contains two seeds facing each other. Once the fruit layers are removed and the seeds dried, they are known as green coffee. They are not yet brown, but often pale green or similar shades.
Roasting changes the beans' colour and develops familiar coffee aromas. Between the red fruit in the field and the aroma rising from a cup lies a sequence of work after harvest.
04 From harvest to cup
Harvesting the fruit, one cherry at a time.
Coffee cherries do not all ripen at once. Green fruit may remain beside ripe red cherries. When selectively picking by hand, workers check the branches, take ripe cherries and leave unripe ones for a later pass.
Walking the rows, looking at the fruit and reaching to pick: repeated movements gradually fill baskets and containers. The harvested cherries are checked for ripeness and damage before the next stage. When to pick and which fruit to choose matter as much as growing it.
Work on the drying beds
Care continues after harvest.
Natural is not the only process used in Yunnan. Other approaches remove the pulp and wash the seeds, or dry them with some mucilage still attached. These post-harvest methods are known as processing, and they affect aroma and flavour. The character of place and variety meets the producer's choices to shape the cup.
Processing, milling & roasting
From Yunnan's harvest to the aroma in your cup.
Inside the red cherries picked on mountain farms are the seeds we know as coffee beans. Freshly picked fruit does not yet have that roasted aroma. The character nurtured by Yunnan's land gradually becomes flavour through post-harvest care and processing.
Processing turns cherries into green coffee and helps shape flavour. In washed processing, for example, pulp is removed, mucilage around the seeds is broken down and washed away, and the beans are then dried. This differs from drying the whole fruit naturally. Even cherries from the same field can develop different aromas and mouthfeel depending on how they are handled.
Processing facilities between the farm and roastery also help protect quality. Workers check moisture, remove the protective layers from dried beans and sort by size and condition. Machines and human inspection work together to identify uneven drying, damaged beans and foreign material. These less visible tasks preserve the care invested on the farm.
From green beans to roasting
Roasting applies heat to prepared green beans to develop their aromas. Roasters observe colour, smell and cracking sounds to judge heat and timing. A medium roast can retain some fruit-like acidity in balance with sweetness and roasted notes. A dark roast can soften acidity and bring fuller roasted aromas, gentle bitterness and body. The same beans can show different faces through roasting.
Some days call for lively acidity; others for a slowly savoured, fuller body. Looking at processing and roast as well as origin and variety opens up more ways to enjoy Yunnan coffee.

Carry the landscape into your next cup.
Fruit grown in mountain fields passes through many hands before becoming fragrant coffee. Next time you drink a Yunnan coffee, picture the red cherries among the leaves and the people harvesting them. Alongside the flavour, the place where it grew may feel a little closer.
