Costa decaf: what the two-shot figure actually covers
The short answer
The dated Costa guide lists 2 mg for two decaf shots from one pod. That is a named preparation, not a measurement of every drink labelled decaf.
Do not multiply by cup size
A larger milk volume does not establish how many decaf pods or shots are used. Verify the recipe before scaling the caffeine. Extra coffee, chocolate or another caffeinated ingredient can make an order differ from the listed pod serving.
A dated source, not a current-recipe guarantee
This record comes from the guide covering 30 April–26 August 2026. A newer recipe was not verified for this release. Use it as a documented historical reference and confirm the current preparation with Costa when the exact dose matters.
Lower caffeine is not zero caffeine
For comparisons, preserve the nonzero decaf figure instead of rounding it away. If you mix regular and decaf coffee, use comparable serving amounts and label the result as an estimate; extraction and preparation still vary.
Educational information, not medical advice. Published, calculated and approximate values have different limits. Check the current product label or recipe when an exact amount matters.

Estimated caffeine remaining over time
These figures apply CaffCalc’s exponential model to the adjusted 2 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 | 2 mg | 2 mg | 2 mg |
| 3 | 1 mg | 1.3 mg | 1.5 mg |
| 5 | 0.6 mg | 1 mg | 1.2 mg |
| 8 | 0.3 mg | 0.7 mg | 0.9 mg |
| 10 | 0.2 mg | 0.5 mg | 0.7 mg |
| 12 | 0.1 mg | 0.4 mg | 0.6 mg |
With the central five-hour model, the estimate falls below 25 mg after approximately 0.0 hours. The faster and slower columns show why one fixed clearance time should not be treated as a personal fact.
