Reasons Behind Breakthrough Value of “Trà Xanh Không Độ”

A Game-Changing Partnership with GEA: Setting New Standards for Clean, Preservative-Free Production

Nearly 20 years ago, Tan Hiep Phat made a bold move that set the foundation for a new era in Vietnam’s beverage industry. It became the first—and remains the only—local company to invest in ten cutting-edge Aseptic Cold Filling systems developed by GEA Group, with a total investment exceeding USD 300 million.

The aseptic cold-fill technology

This aseptic cold-fill technology, hailed as a “21st-century invention,” allows for a closed-loop production process where the product, packaging, and environment are all sterilized. This ensures that beverages like Trà Xanh Không Độ maintain their natural flavour and nutritional integrity without the need for preservatives – an industry breakthrough.

“The aseptic process is a sophisticated, tightly integrated system of preparation, mixing, ultra-high temperature (UHT) sterilization, filling, and sealing—all within a sterile environment,” explains Mr. Vincent Mauer, General Director of GEA Vietnam and the Philippines.

Every bottle of Trà Xanh Không Độ undergoes UHT sterilization and is filled in a sterile chamber using pre-sterilized bottles and caps, with sterile water and environment control—ensuring product purity from start to finish. The result? A green tea beverage that retains the distinctive aroma and mildly bitter notes of high-quality Thai Nguyen tea leaves, while meeting the rising demand for clean-label, health-oriented drinks.

A Beverage That Redefined Its Category

Thanks to this revolutionary aseptic filling technology, Trà Xanh Không Độ has become more than a product—it’s a phenomenon in the Vietnamese beverage market. For nearly two decades, it has consistently ranked as a consumer favorite, enjoyed by millions daily to cool down and reduce stress, according to the brand’s own data.

The ability to maintain shelf stability without preservatives while delivering consistent quality has given Trà Xanh Không Độ an edge few competitors can match. According to Nielsen, 75% of Vietnamese consumers consider it the most flavourful and authentically brewed bottled tea on the market.

Flavour Innovation Backed by Takasago: Crafting a Signature Taste

The success of Trà Xanh Không Độ is not only technological—it’s also deeply sensory. Behind its signature taste is Takasago, a global flavour company founded in Japan in 1920, with over a century of expertise in developing flavours for food, beverages, and fragrances.

Nearly 20 years ago, Takasago joined forces with Tan Hiep Phat to create a new standard in bottled tea. Together, they transformed Trà Xanh Không Độ from concept to category-defining product—delivering the authentic taste of Thai Nguyen tea in a convenient, ready-to-drink format.

“flavour is the soul of any beverage. As a strategic partner, we collaborated with Tan Hiep Phat’s R&D team from the earliest stages to ensure Trà Xanh Không Độ would stand out for its superior quality and distinctive profile,” shares Mr. Jun Sakurai, Executive Director for Southeast Asia at Takasago.

Today, it is exported to over 20 global markets, including some of the world’s most demanding countries such as the United States, United Kingdom, France, Netherlands, Australia, Canada, Japan, and South Korea.
