Starbucks Korea's Sweet Milk Coffee Hits 500,000 Cups in Three Weeks

A single drink imported from Japan's Starbucks circuit has redrawn what brewed coffee looks like in Korea. Starbucks Korea announced on March 18 that Sweet Milk Coffee, launched on February 26, surpassed 500,000 cumulative cups sold in just three weeks, and now accounts for nearly half of all brewed coffee sales across the chain.

The drink is an iced brewed coffee extracted via the drip method and topped with a vanilla cream base, built around a sweet yet light flavor profile that Korean coffee culture has historically had little equivalent for in the Americano-dominant market. Before its Korean debut, Sweet Milk Coffee had circulated as something of a tourist secret at Starbucks locations in Japan, spreading through word of mouth among visitors who sought it out as a "coffee milk"-style drink unavailable back home.

Choi Hyunjung, Head of Food & Beverage Development at Starbucks Korea, pointed to one feature as central to the drink's appeal: the beans used in brewed coffee rotate periodically, meaning the flavor profile of a Sweet Milk Coffee shifts depending on when you order it. "A key differentiator of 'Sweet Milk Coffee' is that customers can periodically experience a variety of unique coffee beans in a single drink," Choi said. She framed the rollout as part of a broader ambition: "Going forward, as an authentic coffee house, we will continue to broaden the range of coffee options available and provide customers with a more distinctive brand experience by continuously expanding our coffee lineup."

Demand has been particularly sharp among coffee beginners and lighter users, with the drink's reduced bitterness cited as a key access point for drinkers who typically find straight brewed coffee a harder sell. Analysts speaking to Maeil Business News Korea connected the surge to what they called the "pixel life" trend, a pattern of short, diverse consumption driven by individual taste rather than habit or routine, which appears to be pulling younger drinkers toward rotating, experiential menu items over fixed daily orders.

The Sweet Milk Coffee numbers land against an already accelerating backdrop for brewed coffee at Starbucks Korea. According to figures the company provided to Maeil Business News Korea, brewed coffee sales grew 24 percent in 2024 compared to 2023, then jumped 96 percent in 2025 compared to 2024. Growth continued into the first two months of 2026, up approximately 30 percent year-on-year through January and February. The category was already moving; Sweet Milk Coffee arrived as its fastest-moving proof of concept yet, establishing itself, in Starbucks Korea's own framing, as a "daily coffee" in a market long defined by the Americano.
