"Drinking cream cheese in a cup of tea might sound a bit weird, but Chinese consumers and particularly young people, love the taste and texture combination these creamy sometimes salty toppings gives to the drinks," said Fonterra Greater China President Christina Zhu.
Over the last two years Fonterra has grown the volume of cream and cream cheese sold to these tea outlets by 500 percent – enough to make around 80 million cream topped drinks every year.
Part of the success of the shops has been driven by social media, with photos and videos of the long queues encouraging people to join them, rather than put them off.
"The long queues outside [Hey Tea] outlets are a common scene in Shanghai," says Zhu.
"The queues often last all day."
Zhu says the massive demand for the unusual tea means an average "bubble tea" shop would consume around 10 metric tonnes of whipping cream every year.
