Eolbaksa energy drink combines three popular ingredients in Korea: ice (“eol-eum”), Bacchus (an energy drink), and Chilsung CIDER. The word “CIDER,” pronounced “Sa-i-da” in Korean, explains the “Sa” at the end of Eolbaksa. Though its origin is unclear, this icy drink likely began as a sauna recovery mix. Today, it’s featured on menus in jjimjilbangs (public bathhouses) across South Korea.
Over time, this energy drink made its way into gaming cafés. Word spread that it worked just as well as commercial drinks. Gamers started mixing their own versions to stay focused during late-night sessions.
A popular image of Eolbaksa shows it in a water bottle, while other cups contain similar blends. One includes Bacchus, crushed pear juice, and Powerade—nicknamed “Power-Bak-Gal-Bae.” These drinks reflect a growing trend: young Koreans are blending stimulants, vitamins, and electrolytes to fight fatigue.
Another common variation is “Bakgalbae,” which combines Bacchus with Galamandeun Bae (crushed pear juice). When mixed with Powerade, it becomes “Power Bakgalbae.” The basic ratio is 1:1:1. Some people prefer “Eolpobi,” which uses ice, Pocari Sweat, and Vita 500.
These DIY drinks usually combine caffeine, vitamins, and electrolytes. They became popular in the early 2000s when energy drinks were rare. Students preparing for university entrance exams created these power mixes to improve focus. Known as “boong-boong drinks,” they followed a simple rule—mix drinks that deliver a stronger boost than coffee.
On YouTube, videos with titles like “Pharmacist’s Secret Anti-Fatigue Drink” and “Nutrition Professor’s Fatigue Cure” often go viral. Viewers ask if the drinks are safe for teens or if there are side effects. Testimonials often mention how the drink helped users stay awake or recover after a short nap.
However, doctors are urging caution. Kang Jae-heon, a family medicine professor at Kangbuk Samsung Hospital, warned that ingredients and intake vary widely. Some mixes can lead to too much sugar or caffeine. He added that electrolyte drinks—designed for athletes—can strain the body when consumed without exercise.
Sim Kyung-won, a professor at Ewha Womans University Mokdong Hospital, said caffeine and vitamins on an empty stomach may irritate digestion. They can also cause palpitations or insomnia.
Why are young people still turning to these blends? Koo Jeong-woo, a sociologist at Sungkyunkwan University, said the trend reflects youth burnout. From a young age, Koreans face constant pressure to succeed. Drinks like Eolbaksa help them push through long days and sleepless nights.
In one cup of this homemade mix lies the story of a generation running on fumes. These students and workers turn to caffeinated blends not just for energy—but to survive in a world that demands their nonstop attention.
