Vietname Oolong tea is steadily strengthening its position in the international market thanks to its consistent quality, distinctive flavor, and modern production techniques. Made from carefully selected tea buds grown in Vietnam’s renowned tea regions, it offers an elegant aroma, a naturally sweet aftertaste, and a beautiful amber infusion. Highly appreciated by domestic consumers, Vietnamese Oolong tea has also become a premium export product enjoyed in many countries around the world.
Introduction to Vietnam Oolong Tea
Vietnam’s warm, humid tropical climate provides ideal conditions for cultivating high-quality tea, especially Oolong tea. Our teas are produced by combining traditional craftsmanship with modern processing technology, preserving the tea’s valuable natural compounds and health-promoting properties.

Overview
Vietname Oolong tea is made from the leaves of the Camellia sinensis plant. Unlike green tea or black tea, it undergoes only partial oxidation-typically ranging from 15% to 80%, depending on the product style. This unique oxidation level creates a perfect balance between the fresh character of green tea and the rich depth of black tea.
In Vietnam, Oolong tea is produced under strict quality control, blending generations of tea-making expertise with advanced processing technologies. Freshly harvested tea buds go through several carefully managed stages, including withering, partial oxidation, rolling, drying, shaping, and packaging. Every step is closely monitored to preserve the tea’s delicate aroma and beneficial natural compounds.
Origin and production process of Vietnam Oolong Tea
Most Oolong tea is cultivated in highland regions located more than 900 meters above sea level. The cool year-round climate, moderate rainfall, and high humidity provide ideal growing conditions, allowing tea plants to produce tender, flavorful leaves with exceptional quality.
The Vietname Oolong tea’s production process is highly sophisticated and typically takes around 32 continuous hours to achieve the tea’s signature taste and aroma:
- Harvesting: Only premium young shoots with two to three leaves are carefully hand-picked to ensure consistent quality.
- Withering: The freshly picked leaves are naturally wilted to reduce moisture and prepare them for oxidation.
- Oxidation: This is the most critical stage, determining the distinctive flavor profile of Vietname Oolong tea. Depending on the desired style, oxidation levels generally range from 10% to 80%.
- Roasting: The leaves are heated to stop the oxidation process while preserving their aroma and flavor.
- Shaping: The tea leaves are either rolled into compact pearls or twisted into long strips, depending on the production style.
- Packaging: Vietname Oolong tea is vacuum-sealed to maintain its freshness, fragrance, and original flavor for an extended period.

How to select and store Vietnam Oolong Tea

To maintain the quality of Vietname Oolong tea for a longer period:
- Store it in a cool, dry place away from direct sunlight and humidity.
