The introduction of the Aussie flat white coffee is being credited with leading the fastest quarterly sales growth for Starbucks in America in eight years.

Starbucks’ Chief Financial Officer Scott Maw said in an interview, the frothless flat white helped boost the company’s second quarter sales for 2015, after it introduced the drink in January.

The popularity of the flat white in the USA is an “endorsement of Australia’s evolving cafe scene” and Starbucks’ adoption of the Down Under style drink “has caught on abroad”, according to Bloomberg.

The success of the beverage in the USA, Asia and also parts of Europe is encouraging baristas from around the world to come to Australia for training, according to Bloomberg.

“Raj and Sharon Sidhu quit their steady public-service jobs in Singapore last year to open a cafe in the city-state,” they report.

For an edge, they spent a month learning the trade in Sydney, because “that’s where our gurus are”, Mr Sidhu said.

Bloomberg is reporting that Australia’s $4billion coffee drinking market “devours more fresh beans per person than any other country”

London cafe owner Peter Hall, from Australia, told Bloomberg, “we’ve perfected how to make a good, strong, milky coffee”. 

Both Melbourne and Sydney claim to have invented the flat white coffee in the 1980s, however earlier in 2015 a New Zealand barista says they started the craze.

“A Wellington flat white is a failed cappuccino,” says the story. The flat white is the “greatest contribution to the world’s cuisine since the pavlova”.
