Back in March 2021, Jungkook introduced the drink ‘TEAZEN Kombucha’ when a fan asked him in a live on the VLive app what he was drinking. Jungkook answered that he had ordered the kombucha powder after hearing it was good and drinks about two bags per day. As soon as Jungkook mentioned the drink, fans immediately began ordering the product online, leading to the shortage in Korea.

One week later, The Korean tea brand TEAZEN revealed that their Kombucha product had risen 500% in sales after Jungkook drank and introduced the drink on his previous Vlive. TEAZEN posted on their Instagram about Jungkook's insane impact on their sales. They wrote, “Just one word from him and a month’s worth of supplies sold out in 3 days. Thank you.”

Following that, the product recorded its highest export ever, with an increase of over 800% compared to the previous month. Japan saw the largest increase, followed by China and the United States. Many major Korean newspapers, including The Donga Ilbo, Korea Economic Daily, Daily JoongAng, and more, reported about the Kombucha craze and how Jungkook's massive influence helped small businesses grow.

By July 2021, the company achieved copulative sales of 50 million sticks. Later, Korean media reported that Jungkook not only boosted the sales of kombucha products that were already being marketed but also caused companies to launch new kombucha products in the market. Multiple Korean firms are competing in the race to launch new kombucha products after his live stream.

As a result, Teazen Kombucha today was awarded '2021 Brand of the Year', proving Jungkook to have an unparalleled brand power and impact in the economic industry.

They also donated 50 Million KRW (43,000 USD) for Korean society, claiming it to be a return of the profit that Jungkook caused them to receive.

And had to launch new branches domestically and internationally to keep up with the orders.
