Taiwan’s minimalist tea sensation Dejeng Oolong Tea Project, beloved by K-pop group CORTIS, will launch its first Hong Kong store in Causeway Bay’s Hysan Place later this month, bringing its signature light, spring, and roasted oolong teas to local bubble tea enthusiasts.
The brand, which has rapidly expanded to approximately 200 locations across Taiwan and opened an overseas branch in Seoul, South Korea, confirmed its Hong Kong debut through a newly launched Instagram account. Construction hoardings spotted at the Hysan Place site have further fuelled anticipation among fans who have long awaited the brand’s arrival.
A Tea-Focused Concept with Three Distinct Profiles
Founded in Taichung, Dejeng Oolong Tea Project distinguishes itself from conventional bubble tea chains by centring its entire menu around oolong tea. The brand offers three roast levels—light oolong (Qing Oolong), spring oolong (Chun Oolong), and roasted oolong (Bei Oolong) —allowing customers to explore the spectrum of flavours that different roasting techniques produce.
This focused approach has resonated strongly with consumers. The brand now operates roughly 200 outlets across Taiwan and has expanded internationally with a store in Seoul, South Korea. Its minimalist, literary aesthetic has earned it a devoted following among young adults and tourists alike.
K-Pop Endorsement Fuels Global Buzz
The brand’s international profile received a significant boost when South Korean boy group CORTIS publicly requested Dejeng’s signature pearl milk tea during their visit to Taiwan. The group ordered the drink with full sugar and full ice, a combination that quickly became a viral trend among their fanbase.
This celebrity endorsement, combined with the brand’s reputation for quality tea, has driven strong demand from Hong Kong consumers who have long awaited a local outlet.

Broader Implications for Hong Kong’s Bubble Tea Scene
Dejeng’s arrival adds to an increasingly competitive landscape in Hong Kong’s bubble tea market, which has seen a surge of premium Taiwanese and regional brands entering the city in recent years. The brand’s focus on oolong tea—rather than the more common black or green tea bases—offers a point of differentiation that could appeal to consumers seeking more sophisticated flavour profiles.
For those eager to try the menu before the official opening, the brand’s Taiwan and Seoul locations continue to serve the full range. Local fans can also follow the Hong Kong Instagram page for updates on the exact opening date and any launch promotions.
