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 105.0 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 | 105.0 mg | 105.0 mg | 105.0 mg |
| 3 | 52.5 mg | 69.3 mg | 78.0 mg |
| 5 | 33.1 mg | 52.5 mg | 64.0 mg |
| 8 | 16.5 mg | 34.6 mg | 47.6 mg |
| 10 | 10.4 mg | 26.2 mg | 39.0 mg |
| 12 | 6.6 mg | 19.9 mg | 32.0 mg |
With the central five-hour model, the estimate falls below 25 mg after approximately 10.4 hours. The faster and slower columns show why one fixed clearance time shouldn’t be treated as a personal fact.
