Scope and limitations
- Every figure links to its own source and carries an evidence label; weaker evidence is never presented as a current first-party exact value.
- Custom drinks and recipe changes may differ from a standard listed serving.
- Rankings describe caffeine quantity; they do not rate health, quality or suitability.
