Which term is used to describe a person who prepares and serves espresso-based coffee drinks?

The term used to describe a person who prepares and serves espresso-based coffee drinks is "barista." A barista is specifically trained in the art of making coffee, often focusing on espresso techniques, milk frothing, and understanding the various coffee brewing methods. Baristas possess knowledge about different coffee beans, their origins, and the brewing processes involved. Their expertise allows them to craft high-quality beverages tailored to customer preferences, making them essential in coffee shops and cafes.

In contrast, a sommelier refers to a wine steward who specializes in wine service and pairing, primarily in restaurants. A coffee roaster is focused on the roasting process of coffee beans, developing the flavors before they reach the barista's hands. A brew master typically pertains to the beer industry, overseeing the brewing process and quality of beer production. Each of these roles plays a vital part in the food and beverage industry, but the barista is specifically devoted to the preparation and serving of coffee drinks.
