Korean Coffee Chains Show Up to 5x Difference in Decaf Caffeine; Stricter Label Rules and Price Hikes Likely

South Korea will tighten decaffeinated coffee labeling from March next year: only beans with residual caffeine at 0.1% or less can be labeled "decaf." A recent comparison of major domestic coffee franchises found residual caffeine levels ranging from 3 mg to 15 mg per drink (up to a fivefold difference). Current rules allowed products that removed 90% of caffeine to call themselves decaf, but because raw bean caffeine varies by variety and origin, final residual amounts differed widely. Brewing methods (cold brew vs. espresso), shot sizes and brand processes also widen the gap. Health-sensitive consumers—pregnant people or caffeine-sensitive customers—may have experienced palpitations, insomnia or anxiety from some decaf drinks. The new standard aligns with international rules (U.S. 0.1%, EU 0.3%) and is expected to boost consumer trust, but will force brands to change bean sourcing and refine production (extraction, cleaning, heating). Deeper decaffeination raises bean costs (currently 20–30% higher) and many shops already add about 500 KRW to decaf drinks, so further price increases are possible. Demand for decaf is growing rapidly—Starbucks Korea sold 36.5 million decaf drinks Jan–Oct this year, up 35% year-on-year—so brands will need to adapt operations while managing potential short-term disruption.
