QuickCheck: Is decaf coffee completely caffeine-free?
By Ali’sha Alix || THE STAR
A long time ago, in the early 20th century, coffee lovers began enjoying a distinct beverage called “decaf coffee.”
Many believed that “decaf” meant a completely caffeine‑free cup, safe for late nights and sensitive stomachs.
But is decaf coffee really free of caffeine?
VERDICT:
FALSE
Despite its name, decaf coffee is not entirely caffeine‑free. The decaffeination process removes the majority of caffeine—usually around 97%—but trace amounts remain.
An average 8‑ounce (≈240 ml) cup of decaf can contain anywhere from 3 to 15mg of caffeine, depending on the beans, size of the coffee, and the method used.
For comparison, a standard 8-ounce cup of regular brewed coffee contains approximately 80 to 100mg of caffeine.
Methods such as the Swiss Water process, liquid carbon dioxide (CO₂), and solvent-based techniques all aim to preserve flavour while minimising caffeine, yet none can remove every single caffeine molecule.
For most people, these small amounts of caffeine are unlikely to produce noticeable stimulant effects. You would need to drink more than ten cups of decaf to reach the caffeine level typically present in one cup of caffeinated coffee.
The next time you sip decaf, remember: it is very low in caffeine, but not entirely caffeine‑free.
