Costa cappuccinos deliver nearly five times as much caffeine as Starbucks ones

Which? study reveals huge disparity in the amount of caffeine delivered by high street coffee chains

Coffee lovers looking for a strong pick-me-up should avoid Starbucks and head to Costa, after it emerged its cappuccinos deliver almost five times as much caffeine - the same as four cans of Red Bull.

Buyers of a Costa medium cappuccino get three shots of espresso and a table-topping 325mg of caffeine, which is around the same as four cups of tea, and way above the Starbucks equivalent containing just 66mg.
