The Foundation: Camellia Sinensis and Its Varietals
At the heart of many traditional Vietnamese teas is the Camellia sinensis plant, the same species that produces most of the world's tea. The final product—be it green, black, or oolong—is determined by the harvesting and processing methods applied to the leaves.
Green Tea: The National Favorite
Vietnamese green tea (Trà Xanh) is the most widely consumed type of tea in the country, appreciated for its fresh, grassy, and vegetal notes. Unlike other forms, green tea leaves are not wilted or oxidized. After being harvested, they are typically heated (often pan-roasted or steamed) to stop the oxidation process, preserving their fresh flavor and vibrant green color. Popular varieties include Thai Nguyen Green Tea, known for its strong taste and sweet aftertaste, and Shan Tuyet Tea, made from ancient, wild-grown trees in the northern mountains.
Black Tea: Robust and Oxidized
Vietnamese black tea (Trà Đen) is made from Camellia sinensis leaves that have been fully oxidized. This process changes the leaves from green to black and gives the tea a more robust, malty flavor compared to its green counterpart. While less common for daily consumption than green tea, black tea is a key export product and serves as the base for many sweetened milk teas.
Oolong Tea: The Partially Oxidized Blend
Oolong tea (Trà Ô Long) involves a partial oxidation process, placing it between green and black tea. This results in a complex flavor profile that can range from light and floral to full-bodied and toasty, depending on the level of oxidation and processing. Vietnam produces high-quality oolong, especially in the highlands of Lam Dong province.
The Scented Teas: A Floral Tradition
In Vietnam, the art of scenting tea with flowers is a cherished tradition that requires immense skill and patience. The most famous scented teas are produced by infusing green tea leaves with fragrant blossoms, a process that can take many days or weeks.
Lotus Tea (Trà Sen): Vietnam's Aromatic Masterpiece
Arguably the most iconic and labor-intensive Vietnamese tea, lotus tea is created by scenting high-quality green tea leaves with lotus flowers. The process involves placing green tea leaves inside fresh lotus blossoms from West Lake in Hanoi and leaving them to absorb the fragrance overnight. This is repeated multiple times—as many as seven for premium grades—requiring over a thousand lotus flowers to scent a single kilogram of tea. The result is a highly prized tea with a delicate and sweet aroma.
Jasmine Tea (Trà Lài): A Fragrant Staple
Jasmine tea is another popular scented variety, made by blending green tea leaves with jasmine flowers. The flowers are mixed with the tea leaves, and the process is repeated until the tea has fully absorbed the floral aroma. This creates a pleasant, calming tea that is widely enjoyed across the country.
The Herbal Infusions: Medicinal and Refreshing
Beyond teas derived from the Camellia sinensis plant, Vietnam has a rich tradition of herbal teas, or tisanes, made from a variety of medicinal plants, roots, and flowers. These are often consumed for their health benefits or as a refreshing beverage.
Artichoke Tea (Trà Atisô): A Soothing Brew
Artichoke tea is a well-known herbal infusion, especially from the Da Lat region. It is made from the flowers, stems, and roots of the artichoke plant and is valued for its mild, naturally sweet taste and health-promoting properties.
Ginger Tea (Trà Gừng): A Warming Remedy
Ginger tea is a simple yet potent herbal remedy, made by steeping slices of fresh ginger root. It is particularly popular for its warming properties and is often consumed to soothe a cold or upset stomach.
