Oolong is a category of tea in its own right, sitting between green tea and black tea. Its distinctive feature lies in its partial oxidation, which can range from 10% to 70%, offering a great diversity of flavours and aromas. This mastery of oxidation, combined with roasting techniques of varying intensity, makes it possible to obtain unique taste profiles.
A complex and meticulous manufacturing process
Transforming Oolong is an art that requires great expertise.
It comprises several essential stages:
- Harvesting: The tea leaves are picked by hand, usually in the morning, to preserve their freshness and aromatic potential.
- Withering: Once harvested, the leaves are laid out on the upper floor of the tea factory, or generally in well-ventilated areas, for several hours. This step removes some of the moisture and prepares the leaves for oxidation.
- Oxidation: This is where all the specificity of Oolong lies. The leaves are placed in a warm, humid atmosphere that promotes oxidation. The artisan carefully monitors this process, regularly stirring the leaves to distribute the oxidation evenly.
- Fixing: Once the oxidation is judged optimal, the leaves are heated rapidly in large rotating drums to stop the process and lock in the aromas.
- Rolling: The leaves are then worked to give them their final shape. Some varieties are rolled into pearls, like nunshen’s new Oolongs, while others take a more open form.
To roll nunshen’s Taiwanese Oolong teas into pearls, the tea leaf is placed in a cloth bundle that is turned for a certain time. This bundle is repeatedly reopened to turn the leaf so that it curls tightly on itself.
- Drying and roasting: Finally, the leaves are dried at low temperature, and sometimes roasted, which adds woody, toasted or caramelised notes.

A varied aromatic palette
Oolongs stand out for their exceptional aromatic richness. Depending on the degree of oxidation and the method of manufacture, they can develop floral, fruity, woody or even toasted notes.
Lightly oxidised Oolong teas often recall green tea, with notes of white flowers and honey, while heavily oxidised or roasted Oolongs offer flavours of candied fruit, cocoa or hazelnut.
How to prepare an Oolong?
Brewing Oolong varies according to its type and degree of oxidation. In general, we recommend:
- Water between 85 and 95°C.
- A steeping time of 1 to 3 minutes, with the option of several successive infusions.
- A dosage of about 2 grams per 100 ml of water.
Some varieties, particularly the pearl-rolled ones, reveal their full potential after several infusions, offering an evolution of aromas over the course of the tasting.
A tea between tradition and innovation
Enjoyed in Asia for centuries, notably in China and Taiwan, Oolong is now establishing itself as an exceptional tea worldwide. Its aromatic complexity and the richness of its variations make it a unique experience for tea lovers.
Whether you are a novice or an enthusiast, discovering Oolong means diving into a fascinating world where each leaf tells a story of craftsmanship and patience.
