How to interpret the comparison
- Costa’s published recipe table assigns two Signature Blend shots to the Medium Latte and three to the Medium Cappuccino.
- Combining that recipe table with Costa’s caffeine-by-shot figures gives 200 mg for the Latte and 325 mg for the Cappuccino.
- These are transparently calculated values rather than direct laboratory measurements, and Costa notes that natural and preparation variation occurs.
