Our obsession with the perfect brew dates back to the early '50s, when coffee shops opened in Melbourne, introducing us to the sounds of espresso machines. Coffee is a source of furious pride and unnecessary intense competition. This competition for the best coffee led us to invent the flat white, the long black, and spread them around the world.
