Pinkberry, the low-fat Korean frozen yoghurt concept known in the US as “crackberry” for its apparently addictive qualities, will make its long-awaited debut in the UK early next month, in London’s Selfridges.

The company, which currently operates over 130 sites around the world, has been rumoured to be looking to open in the UK for the last four years and recently appointed property agent Harper Dennis Hobbs to seek sites in London and around the country.

Ron Graves, chief executive of Pinkberry, said: “Since its launch in West Hollywood in 2005, Pinkberry has quickly become a global brand and being in London is a key step in our growth.”

Tanya McMullen, Selfridges buying manager, said: “It has a wonderful concept, executed to the highest standard, is accessible to all and yet manages to create a level of aspiration and a celebrity following few brands manage to build in such a short period of time. We believe this is the perfect time to welcome Pinkberry to the UK and have every hope for an extraordinary response from our customers.”

Earlier this year, the company announced plans to open in up to 17 new international markets by the end of this year.

The chain is expected to add 30 new international sites by the end of 2011.

The company opened its first site in Russia in March, with further sites opened in Kuwait and Peru in May.

The group is also expected to open franchise locations in Turkey, the Philippines, Canada and Morocco, as well as in more nations in the Middle East, this year.

Starbucks president and chief executive Howard Schultz sits on Pinkberry’s board.
