Six first-party source reviews

UK coffee-chain caffeine guides

These guides separate figures a chain actually publishes from information it does not. CaffCalc will not move a caffeine value between countries, infer it from nutrition, or repeat an untraceable third-party number.

A useful “no data” resultNot every chain publishes caffeine in milligrams. Those gaps are documented because an honest missing value is more useful than a precise-looking estimate without a defensible source.
