The yogurt chapssaltteok that draws lines at a Seongsu-dong dessert shop is now in GS25 freezers nationwide.
GS25 launched it on September 3, 2026 as a store exclusive, priced at 3,900 won per pack.
On launch day alone, 100,000 packs sold.
This post covers what the product is, how the frozen and thawed versions differ, whether the price makes sense, and what to check before heading to a store.

Hanjungsun Yogurt Chapssaltteok GS25: the two-texture tteok you can eat frozen or thawed
The product is a frozen dessert: tangy yogurt cream wrapped in a chewy rice-cake shell.
The rice-cake part is what sets it apart from a standard ice cream sandwich.
It is the signature item of Hanjungsun, a dessert shop that started on Seongsu-dong’s cafe street and grew through social media into a stop on many tourist routes.
The GS25 version is a frozen reinterpretation of that shop item, made with manufacturer Lolomello.
There are two ways to eat it, and they give different results.
Eaten straight from the freezer, it has a gelato-like texture.
Left to thaw, the rice-cake shell turns chewy, closer to classic tteok.
The thaw level is the main dial, since a longer thaw moves it from ice cream toward rice cake.
One thing to know before comparing it with the shop version: the frozen pack is a convenience-store reinterpretation, not a duplicate.
It cannot carry the fresh fruit topping, the lucky-pouch packaging, or the shop atmosphere of the Seongsu flagship.
The taste comparison that matters is frozen vs thawed, not store vs store.

Launch day: 100,000 packs and a sold-out test run
The demand signal came before the nationwide launch.
On August 28, GS25 previewed 400 packs at two stores, 200 each near the Gangnam flagship and at Incheon Airport.
Both batches sold out early, and Korean media reported the airport batch gone in about 15 minutes.
The official launch followed on September 3 across GS25 stores nationwide.
First-day sales reached 100,000 units, which put the product at the top of single-item revenue in GS25’s ice-cream and frozen dessert category.
At 3,900 won per pack, that first day works out to roughly 389 million won in revenue from one item.
Purchase-verification and taste-review posts spread on social media within days of the launch, and ET News covered the viral response on September 4.
For a single convenience-store item, that pace is unusual — and it explains why some stores may run short.
Why foreign travelers were buying it at the airport
The Incheon Airport test batch drew foreign customers who photographed their purchases and posted them online.
That is not an accident of placement.
Hanjungsun is listed on Visit Seoul, the city’s official tourism site, in its cafe and dessert category — a marker of its status as a visitor destination.
The numbers behind the brand explain the airport demand.
Hanjungsun grew from a Seongsu cafe stall into department store food halls before the convenience-store deal, and more than 3 million foreign tourists visited Seongsu-dong in 2024 according to the district office.
For a traveler who cannot fit Seongsu into an itinerary, an airport convenience store freezer is the one place the item is reachable without a detour.
GS25 picked the brand for exactly that reach, aiming to give younger shoppers and foreign visitors a reason to stop in.
More Seongsu and tourist-area K-desserts are expected to follow the same path into convenience stores.
Is 3,900 won worth it?
As a convenience-store dessert, 3,900 won is not cheap.
A typical single ice cream bar costs well under that.
The price reads differently once the alternative is a trip to Seongsu: queuing at a takeout-only shop with no seating, for a pack you would then carry around.
Seen that way, the pack works as an experience ticket.
It is a low-cost way to try the dessert that tourists queue for, without the queue.
What it does not replace is the store visit — the fresh fruit versions, the bokjumeoni gift packaging, and the shop itself stay exclusive to Seongsu.
The practical choice depends on the goal.
If the goal is tasting the viral item, 3,900 won at the nearest GS25 covers it.
If the goal is the original shop experience, the frozen pack is a preview, not a substitute.
Korean tteok vs Japanese mochi in the freezer aisle
The same week, Seven Eleven relaunched Chitoru Choco Mochi, a Japan-sourced line, in four types including Injeolmi, Choco, Shine Muscat Tart, and Sweet Potato.
Chitoru sold 130,000 units in its first two months after the 2025 launch, and stock for the relaunch increased roughly threefold.
The comparison is stark.
GS25’s chapssaltteok moved 100,000 units on day one; Seven Eleven’s mochi needed two months for 130,000.
At the day-one pace, the chapssaltteok would pass that two-month total in about ten days.
The pairing matters less as a scoreboard than as a sign of where Korean convenience stores are heading.
Both chains are importing SNS-famous, tourist-area desserts into their freezers, and competition over distribution rights to hit dessert brands is intensifying.
For shoppers, that means more formerly queue-only desserts becoming corner-store purchases.
Before you buy
The product is a GS25 exclusive, so other convenience chains do not carry it.
Whether every GS25 location is stocked, or only major and tourist-area stores, was not confirmed at launch — travelers should treat airport and central Seoul stores as the safest bet.
Restock schedules after launch day were also not announced.
For eating, decide the texture first.
Straight from the freezer gives the gelato-like version; a thaw gives the chewy tteok version.
A recommended thawing time was not published, so the thaw level is best adjusted by feel rather than a set clock.
Demand is expected to rise through the Chuseok travel season in September 2026, when airport and tourist-area convenience stores see heavier K-dessert traffic.
Anyone who wants a pack during that window should buy earlier in the day rather than late.
