When you’re running on fumes nothing helps you through the day like a good, strong cup of coffee. New research has been looking at caffeine levels at different chains in the UK to determine just where that strongest, or weakest, cup can be found.
Consumer group Which? Has been measuring the caffeine levels in espresso, cappuccino and filter coffee at Greggs, Starbucks, Caffe Nero, Costa Coffee, and Pret A Manger to see just where to go to get the best energy boost. And the results show that some coffee shops will provide you with a much stronger boost than others.

"Most of the time this shouldn’t be an issue but if you drink a lot of coffee or need to limit your caffeine intake you might want to consider what you’re ordering and where from."
The research shows that a single espresso from Pret A Manger contains six times more caffeine than the same drink at Starbucks. And if you’re more of a cappuccino drinker, Costa offers the strongest one with 325mg of caffeine per cup.
The strongest and weakest coffees
Costa had the strongest medium cappuccino with 325mg of caffeine - equal to four cups of tea
A Starbucks cappuccino contained the least at 66mg - less than the 75mg in a single tea bag
Greggs and Pret a Manger had the second and third-strongest cappuccino at 197mg and 180mg respectively
Pret’s single espresso was strongest at 180mg
Starbucks’ espresso was bottom of the table at just 33mg
Pret topped the list for the most caffeinated filter coffee at 271mg a cup
Greggs was a close second at 225mg
Starbucks was again the least caffeinated at 102mg
