Seongsu Beer Pop-Ups: How Cass World and Forest Brewery Turned Beer Into a Brand Experience

Seongsu beer pop-ups have become more than quick tasting booths; they have been used as immersive brand stages where beer makers explain a new package, a renamed product, or a wider culture around drinking. For anyone following Seongsu Craft Beer and lifestyle pop-ups, the most useful examples are Cass World in 2025 and SevenBrau’s Forest Brewery in 2023, both of which show how the neighborhood has been used to turn beer into a walk-through story.

Seongsu Beer Pop-Up Spotlight: Cass World at MM Seongsu

OB Beer operated the Cass brand pop-up store “Cass World” at MM Seongsu in Seongdong-gu, Seoul, from April 11 to April 20, 2025. The event was built around Cass’s refreshed package design and gave visitors a physical way to understand the brand’s new visual direction, rather than simply seeing the updated cans or bottles on a shelf.¹

The strongest visual idea came from the new package’s waterfall-inspired concept. The site included an ice cave, a 6-meter-high cascade waterfall, and a draft beer dispenser designed around the idea of a mineral spring. That kind of staging matters because it shows why Seongsu has become such a natural fit for beer pop-ups: the neighborhood gives brands room to build environments that feel closer to exhibitions than ordinary retail promotions.¹

Cass applied the new VBI package across Cass Fresh, Cass Light, Cass Lemon Squeeze, and Cass 0.0. OB Beer also explained that the Cass logo font had changed for the first time in six years, while the package design had changed for the first time in five years. In other words, Cass World was not just a seasonal event; it was a public-facing launch space for a major brand refresh.²

There was also clear demand before the doors opened. A 400-person advance reservation quota sold out, and the pop-up ran for 10 days. For a beer brand, that suggests the appeal was not limited to tasting. People were responding to the full package: design, space, photo-friendly installations, and the feeling of catching a short-run Seongsu event while it was available.²

Cass described the space as one where visitors could enjoy the reborn Cass, based on “freshness,” through all five senses. Another Cass representative called it a grand visualization of the brand’s core value, “the moment when freshness pours down like a waterfall.” These quotes are polished brand language, of course, but they also capture what the pop-up was trying to do: make an abstract product message feel physical.¹²

Why Seongsu Works for Beer Brands

Seongsu’s beer-pop-up story did not begin with Cass World. SevenBrau operated “숲속양조장:세로 ON 대표,” naturally translated as “Forest Brewery: Sero ON Daepyo,” on Seoul Forest-gil in Seongsu from May 13 to May 28, 2023. The purpose was specific: SevenBrau was introducing the renamed “Daepyo Wheat Beer” after the end of its trademark contract for “Gompyo Wheat Beer.”³

That detail is important because it shows how a pop-up can help solve a communication problem. A renamed product can confuse drinkers, especially when the liquid itself is tied to a familiar identity. SevenBrau used the Seongsu store to explain that the beer had changed its name and package, while also focusing attention on the “Daepyo Wheat Beer” identity. Cookie News reported from the site on May 16, 2023, noting that the tasting beer available at the pop-up was Daepyo Wheat Beer, while other craft beers were sold without tasting.⁴

The Forest Brewery setup also leaned into education. It displayed the main ingredients of Daepyo Wheat Beer, the characteristics of its taste, the product development history, and actual brewing equipment. That makes it a useful contrast with Cass World. Cass used a large-scale sensory environment to dramatize freshness and design renewal; SevenBrau used its space to explain a product transition and reconnect drinkers with a wheat beer under a new name.³

SevenBrau Vice President Kim Hee-sang described the product as one that popularized “the attractive taste of craft beer.” The comment fits the broader role of Seongsu beer pop-ups: they are not only about novelty. They can also help translate craft beer, renamed products, and brand changes into something approachable for casual visitors.³

From Pop-Up Events to Seongsu Craft Beer Culture

A third piece of the picture is Seoul Brewery’s Seongsu flagship store. HeyPop introduced it as a flagship opened on Yeonmujang-gil in Seongsu in April 2023. The space spans seven floors including the basement and covers about 350 pyeong, with a brewery, taproom, cafe, dining area, culture hall, and rooftop.⁵

That is not a temporary pop-up in the same way Cass World or Forest Brewery was, but it helps explain the neighborhood context. The Seongsu branch was planned as a complex cultural space where live performances, clubs, flea markets, and pop-up stores could take place. In that sense, beer in Seongsu is not presented only as a beverage category. It is often linked to design, performance, shopping, and neighborhood wandering.⁵

This is also where comparisons to Brooklyn become easy to understand, as long as they stay grounded. Economy Chosun described Brooklyn Brewery as a craft beer brewery in East Williamsburg, Brooklyn, New York. The same article noted that its logo was designed by Milton Glaser, known for “I Love New York,” and referred to Brooklyn Brewery as New York’s top-selling craft beer.⁶

That background does not mean Seongsu is copying Brooklyn. The better reading is that both places show how beer can become part of a neighborhood’s cultural identity. In Seongsu, the evidence comes from event spaces, flagship venues, package-renewal pop-ups, and brand storytelling. The result is a local scene where beer is packaged together with design and experience, not just poured into a glass.

The key takeaway is simple: Seongsu beer pop-ups have worked because they give visitors a reason to care before the first sip. Cass World turned a package redesign into a waterfall-themed experience, SevenBrau’s Forest Brewery explained a major product renaming, and Seoul Brewery’s flagship showed how craft beer can sit inside a broader cultural venue. Together, they make Seongsu Craft Beer feel less like a single trend and more like a flexible stage for beer brands, drinkers, and neighborhood culture.
