Coffee definitions: The language of espresso

Coffee definitions: The language of espresso

As published in BeanScene magazine 

For expert tasters, baristas and cafe owners alike, speaking the language of espresso is an essential skill.

Long gone are the days of ordering or preparing a simple ‘cup of coffee’. As a sophisticated coffee culture has evolved, so has the vocabulary to describe its every nuance. The last decade has even seen the emergence of entirely new words and phrases that help deepen our understanding of espresso.

Coffee definitions enables tasters, baristas and cafe owners to articulate and share knowledge – a key part of professional growth. Becoming a great coffee creator begins with developing a palate sophisticated enough to distinguish between a good coffee and a great one. Similar to terms used in fine wine, coffee lingo helps define parameters of taste, texture and technique. Being able to talk the coffee talk and describe a pour enables a culture of training, essential to the success of any café.

The essence of any barista’s vocabulary is the standard café menu. Most of this has its roots in the Italian language. The famed cappuccino, for example, derives its name from the Capuchin monks. Similarly, the macchiato comes from the Italian word for ‘stained’, and ristretto refers to a ‘restricted’ shot.

Below are some key words and phrases that form the basis of coffee definitions. By no means is this a comprehensive glossary though – it’s always worth considering furthering your knowledge with a barista training course.
