Korean Dalgona Coffee Evolution

Dalgona coffee — whipped instant coffee foam over iced milk — became one of the first pandemic-era viral recipes in 2020 and inspired a genre of Korean café innovations that continued dominating in 2025. Korean cafes introduced dalgona matcha, dalgona biscoff, and sweet potato coffee variations that spread globally via TikTok. Seoul's café density (one per 50 residents) makes it the world's most coffee-saturated city.
