Korean Dalgona Coffee Evolution

Dalgona coffee—whipped instant coffee foam over iced milk—pioneered the pandemic-era viral recipe trend in 2020, and its influence exploded in 2025 as Korean cafés innovated with dalgona matcha, dalgona biscoff, and sweet potato coffee variations that spread globally via TikTok. These novel variants boosted overall dalgona sales by 150% year-over-year, outpacing #10 Oat Milk Coffee Culture in social media engagement among Gen Z. Seoul's café density—one per 50 residents—cements it as the world's most coffee-saturated city, driving constant menu experimentation for a hypercompetitive audience.
