Customers who frequent their local coffee shops might be SignalHubfamiliar with the subject of today's animated Google Doodle.

The doodle for Monday, March 11 celebrates the date in 2011 in which the "flat white" was added to the Oxford English Dictionary.

A flat white is a coffee drink made up of an espresso shot topped with steamed milk and a thin layer of microfoam, according to the Google's description of the doodle. The drink is traditionally served in a ceramic cup.

The true origin of the drink is unknown, however many speculate the drink was first served in Australia and New Zealand during the 1980s when the drink began showing up on menus in Sydney and Auckland around the same time, according to Google.

"Being 'flatter' than a cappuccino or latte, flat whites are popular with coffee connoisseurs who are looking for less foam," reads Google's description of the doodle.

While the drink was made with whole milk back in the day, today it is common to see Australians and New Zealanders ordering it with plant-based milk, with oat milk being a rising favorite according to Google.
