Which? says it asked five chains for caffeine information and used online guides; many figures were obtained through brand press offices. The brand’s public UK menu doesn’t publish this value, so treat it as a reported figure rather than a first-party public listing.
Estimated caffeine remaining over time
These figures apply CaffCalc’s exponential model to the adjusted 208 mg starting value. They are calculations, not measurements of caffeine in a particular person.
| Hours elapsed | 3-hour half-life | 5-hour half-life | 7-hour half-life |
|---|---|---|---|
| 0 | 208 mg | 208 mg | 208 mg |
| 3 | 104 mg | 137.2 mg | 154.5 mg |
| 5 | 65.5 mg | 104 mg | 126.8 mg |
| 8 | 32.8 mg | 68.6 mg | 94.2 mg |
| 10 | 20.6 mg | 52 mg | 77.3 mg |
| 12 | 13 mg | 39.4 mg | 63.4 mg |
With the central five-hour model, the estimate falls below 25 mg after approximately 15.3 hours. The faster and slower columns show why one fixed clearance time shouldn’t be treated as a personal fact.
