Which? analysis reviews caffeine levels in hot drinks sold by five popular high-street retailers and finds substantial differences between products. The study identifies the drinks with the highest caffeine concentrations, including one popular beverage described as having an amount of caffeine comparable to multiple energy drinks.
The reports cite Which? as the source of the findings and focus on consumer-facing comparisons to help readers understand caffeine strength across common choices. The outlets describe the results as “astonishing,” but they do not provide additional independent testing. Both sources draw attention to the implications for people who limit caffeine intake, such as those seeking to avoid high stimulant doses from everyday drinks.
Overall, the coverage agrees on the core point: Which? measures and ranks caffeine content in hot drinks from selected retailers, highlighting that some drinks contain far more caffeine than others. The main difference is tone, with both outlets using similar emphasis on the highest-caffeine item and the study’s striking comparisons.
