WonderBrew Kombucha made history by clinching six prestigious titles at the World Kombucha Awards 2025 in Barcelona, Spain. The brand was founded in 2018 by Joseph Poh Wen Xian and Loke Boon Eng.

In 2018 Joseph began a journey to transform his gut health. He would walk the aisles of the supermarket, searching for the latest health foods and supplements to try. On one of these fateful trips, he discovered kombucha (which he had never tasted before). Going with his gut instinct, he took a bottle home and, in his words, “It was love at first sip.” He did not know it at the time, but his first purchase was Boon’s brand of kombucha.

The drink calmed his indigestion and piqued his business senses. A Google search for local kombucha led him to a brewing class by Boon. Joseph signed up for the class. The two were still strangers at this point. After that, Joseph began home-brewing kombucha for personal use as his entrepreneurial spirit began to fizz. When he heard about the kombucha hype overseas, he knew he was sitting on a pot of fermented gold. After extensive study of the local market, Joseph approached Boon to join him as a partner, and WonderBrew was born.

I had a sense that this could be a business opportunity in Malaysia. Because it was so rare and it was expensive with mostly the imported products from imported brands from overseas. And it was really not accessible as well. So, based on this market gap, we worked together to create a truly local brand called Wonderbrew in 2018.

WonderBrew has grown to become Malaysia’s leading kombucha producer, with more than 2,000 retail touchpoints across supermarkets, convenience stores, cafes, hotels, and restaurants nationwide. They now employ more than a dozen people. They are on record as aiming to double production in 2026 and to expand their footprint across Southeast Asia, with a focus on the Singapore and Indonesian markets. Since its founding in 2018, it has sold more than 1.5 million bottles.

To ensure consistent quality and preserve the freshness of their product, they brew in small batches.

Joseph and Boon made history on the global stage by clinching six prestigious titles at the World Kombucha Awards 2025, held in Barcelona. In its first-ever international competition, WonderBrew emerged as one of the biggest winners at this year’s event, clinching one gold, four silvers and one bronze, across both taste and design categories, (see listings below). The feat marks the first time a Malaysian brand has won at the World Kombucha Awards and the first time an Asian brand has secured six titles in a single award year.

Wonderbrew offers a dizzying range of both kombucha and jun flavors. Many use local sources of ingredients and are heavily oriented to fruity flavors:

When we first launched our original flavors, we found that based on feedback, something fruity and something on a slightly sweeter side helps new users get used to kombucha. So from there on, we focused very much mostly on fruit-based infusion because for especially new consumers, they don’t really like the vinegary taste.

To celebrate their achievement in Barcelona, they released a limited edition Winning Brew Collection featuring all their five award-winning flavors:

In addition to heavily promoting its World Kombucha Awards, Wonderbrew effectively uses social media to promote its beverages. They have over 13,000 Followers on Instagram—the most of any Malaysian brand—and focus on young, sporty, even wealthy consumers. They also celebrate national holidays and religious festivals, including Diwali, Thaipusam, Ramadan, and Chinese New Year.

The majority of their sales are through retail outlets. You will find Wonderbrew in high-end Malls, grocery stores, and fitness centers. They distribute across Malaysia. They also contract pack for other producers.

The brand prides itself on sourcing locally and partnering with Malaysian farmers to recycle production waste, reinforcing its commitment to sustainability and community empowerment.
