A new multi-million pound rejigg of their European operations will see lattes, cappuccinos and other coffee drinks get not one but two shots of espresso, after a sharp increase in the number of people who had already been ordering their drinks with the extra caffeine hit. 

Starbucks UK and Ireland managing director Kris Engskov said: “

Customers are becoming more experienced, more sophisticated and many more are looking for a stronger taste.

“The UK is the most competitive coffee market, more so even than the States. But we’ve seen a big change in consumers’ behaviour, with the number of additional shots we sell up 60 per cent in the last two years.” 

The new recipe comes a part of a move to overhaul the American coffee giant’s UK operations as part of an £8million project to redesign cafes in the capital with a more local feel and look. 

It will also see the company open hundreds of new stores across Britain in the next three to five years, increasing its presence from 700 branches to over 1000, and entertaining in to a coffee war with other high street retailers. 

There are those though who are worried that this double hit standard will cause Britons to develop a higher tolerance to caffeine.
