Everything you need to know about what's in your cup of coffee 

One in three Irish people now buys coffee at least once a day - but can you get too much of a good thing? 

Sweet coffee aroma, coffee beans and morning coffee

Are you getting a bigger caffeine kick from your coffee than you bargained for? A recent report by the consumer watchdog, Which? compared the caffeine content in espresso, cappuccino and filter coffee from various high street chains, including Costa, Pret and Starbucks, and found some coffees provided five times as much caffeine as others.

If you are partial to a cappuccino from Costa on the way to work, you will certainly be buzzing through the morning as it was found to contain nearly five times as much caffeine as one from rival chain Starbucks. The survey found a “massive” 325mg of caffeine in a medium Costa cappuccino, about the same amount contained in four cups of tea. A Starbucks equivalent contained just 66mg of caffeine and there is 80mg caffeine in a 250ml can of Red Bull.
