The Full Story

A plain summary built from the channels that reported this story.

A new study has revealed significant variation in caffeine levels across high street coffee shops, raising questions about labeling and consumer awareness. The research found that a medium-cost cappuccino can contain more than three times the caffeine of the same drink at Starbucks, equivalent to around four cans of Red Bull.

Experts are advising consumers to be mindful of where they buy their coffee, as the amount of caffeine in a drink depends on the size and type of coffee used. The findings suggest that without clear labeling, customers may unknowingly consume far more caffeine than they expect.

The study highlights a potential gap in information for coffee drinkers, particularly those who are sensitive to caffeine or monitoring their intake. While the exact brands and methodologies were not detailed in the coverage, the core message is clear: not all high street coffees are created equal when it comes to caffeine content.

This variation could have implications for public health advice, especially for pregnant women, people with heart conditions, or those who limit caffeine for other reasons. The study adds to calls for more transparent labelling in the coffee industry, so consumers can make informed choices.
