The London Coffee Festival, which is in its first year, is part of the UK Coffee Week and aims to raise funds and awareness for clean drinking water for communities in coffee producing countries around the world.
A team of over 100 UK baristas produced 12,005 espressos in one hour, using 31 commercial espresso machines. This equates to 3.33 espresso shots per second.
The official Guinness World Record was held by a Polish barista team with 3,386 in March 2010, but an unofficial record was claimed by a team from Brisbane, Australia in October last year making 5,061 espressos.
The UK team’s effort was submitted to the Guinness World Records team on Monday.
Jeffrey Young, Managing Director of consultancy Allegra Strategies, the company behind the event said: “This record is a tremendous achievement and really shows the rest of the world London’s leadership in artisan ‘Third Wave’ coffee culture.
“London offers best-in-class food and coffee with many visitors coming here to learn from trends in this great city.”
