Many young people start their morning with a bottle of Number 1. For them, it is not only a source of energy and alertness but also a declaration of green living: clean, preservative free, and environmentally friendly.

“I don’t drink Number 1 just to stay awake,” Minh shared. “I drink it because it’s clean. Clean in the way I expect from everything I consume.”

For Gen Z, choosing a drink is also a way to express identity. From their smartphone to their canvas tote bag to their bottle of Number 1—everything reflects their commitment to sustainable living. According to NielsenIQ, 86 percent of Vietnamese consumers are willing to pay more for eco friendly products, and 70 percent reject beverages with preservatives.

Just a few sips of Number 1, and Minh immediately feels the difference: a strong, refreshing taste, cold and invigorating, energy spreading through his whole body, helping him finish the work ahead while staying confident in his clean, sustainable choice.

Aseptic: A Hundred-Million-Dollar Leap Toward a Preservative-Free Product

For Number 1, Aseptic technology is more than a process. It is a commitment to delivering the best value to Vietnamese consumers.

Nearly twenty years ago, when many questioned the company’s decision to invest hundreds of millions of dollars into this technology, its leaders affirmed:
“We are not afraid of risks. The peace of mind and long term benefit of consumers matter more. Compared to that, even a hundred million dollars is a small price.”

Aseptic cold fill technology—the “hundred-million-dollar decision”—enabled Number 1 to create Vietnam’s first preservative free energy drink. Behind this advanced production line is a commitment to consumer well being and international quality standards.

Number 1 chose the “difficult road”: accepting risks and investing heavily in what was considered one of the greatest beverage innovations of the 21st century. The goal was simple—preserve natural flavor and nutrients, maintain absolute sterility, and create a cleaner, safer, preservative free drink.

Vincent Mauer, General Director of GEA Vietnam & Philippines, explained:
“Aseptic is a technology that protects the quality of every drop. It not only makes beverages taste better but also extends shelf life, stabilizes quality, and most importantly, eliminates the need for preservatives.”

With nearly two decades of Aseptic investment, Number 1 built the foundation for major milestones: Halal certification (2016), U.S. FDA approval (2017), and exports to more than 20 countries. Behind these achievements is the company’s principle:
“Quality is not just for competition. It is for serving consumers.”

Driven by Passion, Committed to a Greener Future

Beyond clean products, Number 1 also works to reduce carbon emissions directly on its production lines, contributing to Vietnam’s Net Zero 2050 goal.

With Aseptic cold fill technology, Number 1 became the first preservative free energy drink in Vietnam nearly two decades ago.

According to Mauer, GEA’s seventh generation Aseptic technology—following ISO 14021—focuses on saving space, water, and energy.

Each seventh generation Aseptic line reduces water consumption by up to 91 percent. This saves companies like Number 1 around 97,500 cubic meters of water annually—enough for 2,100 people for one year.

“GEA aims to minimize PET usage as much as possible. This is where we can make the biggest impact,” Mauer noted. Aseptic allows for greenhouse gas reductions through lighter plastic use and reduced water consumption.

He pointed out that in Vietnam, the use of seventh generation Aseptic technology has cut the weight of Number 1 bottles by 50 percent—from 27 grams to 13.5 grams—reducing CO2 emissions by 20 percent per bottle.

“This enables Number 1 to achieve its sustainability goals,” he said.

Every time someone chooses Number 1, it is more than grabbing an energy drink. It is a practical contribution to Vietnam’s Net Zero 2050 mission.

Number 1: Where Passion Meets Responsibility

According to a PwC Vietnam consumer study, 96 percent of Vietnamese consumers are willing to pay more for products from companies known for ethical and sustainable practices.

This is why Number 1 has been trusted and loved by millions of young Vietnamese for more than two decades. It is not only an energy drink. It is a preservative free companion that fuels passion, encourages courage, and inspires people to dream, move forward, and conquer challenges.

Aseptic technology allows Number 1 to embrace true green manufacturing. Every bottle not only fuels passion and energy but also contributes to Vietnam’s Net Zero 2050 journey.

From office workers and ride hailing drivers, to engineers, entrepreneurs, and street performers, Number 1 is always ready to energize everyone in their own way.

In the warm golden light of year end afternoons, you take a sip of Number 1. The bold flavor spreads instantly, awakening the mind and giving you the focus to give your day everything you have.
