The ultimate "Sold Out King" Jungkook not only causes product to sell out, but what's more remarkable is his massive impact to the growth of thebusinesses. Previously, Jungkook had caused South Korea's P&G supplier, KCI's share price to increase by 11% after he made 2 months-worth of Downy sold out in just a day. He made headlines many times for growing small and medium enterprises into huge profitable companies like what happened to modernized hanbok company Zijangsa, and tea company TEAZEN. All these speak volume of Jungkook’s top-tier brand power.

Recently, The Korea Economic Daily Global Edition reported that the majority shareholder of South Korea’s TEAZEN Co. is seeking to sell ownership of the company, attracting multiple potential buyers after Jungkook revealed himself as a regular drinker of its Kombucha product during his live streaming in February.

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

In March, TEAZEN recorded 800% increase of its export from the previous month, in which Japan, China and United States saw the largest increase. The news about TEAZEN growth kept making headlines, as Korean media later on reported that TEAZEN’s Kombucha sales had increased by 1800% in China. Orders from China and Japan saw huge increase while the company was expanding its list of countries to which they export, adding Australia, Hong Kong, Singapore and Mongolia.

At one point, TEAZEN’s Kombucha became a trending food item on Shopee, as announced by Shopee Singapore. They tweeted, “Tried #JUNGKOOK's Teazen Kombucha Powder yet? This weeks trending food item is Kombucha! 🤩 If not, what are you waiting for?!”

Jungkook’s Kombucha craze also hit hard in South Korea. Back in March, Costco Korea had limit TEAZEN’s Kombucha lemon purchase to 1 packet per membership, due to continuous insane demand.

Many major Korean newspapers including The Donga Ilbo, Korea Economic Daily, Daily JoongAng and Seoul Economic Daily reported about the Kombucha craze and how Jungkook's massive influence helped small businesses grow.
