Where Did Coffee Originate and How Does It Shape Espresso?
Coffee drinking spread from Ethiopia and the Arabian Peninsula, and the brewing terms used today trace a different path. Espresso originated in Italy in the early 20th century, forced through finely ground coffee by hot water under pressure; before the mid-1940s it relied on steam pressure alone until the spring-piston lever machine made the modern form possible.
Black coffee is any cup that contains only coffee, whether espresso or americano, with no added ingredients; once milk goes in, the drink moves toward a latte. Espresso extraction uses water near 92 degrees Celsius at about 9 bars of pressure through a fine grind, giving a thicker, heavier body with more dissolved solids per unit volume than drip coffee.
The classifications in the coffee world are often confusing—what exactly is the logic behind names like espresso, latte, and americano? Today, Front Street Coffee will discuss the definition boundaries of black coffee and how to easily make an authentic latte at home. Simply put, as long as the cup contains only coffee itself with no additional ingredients, whether it's espresso or americano, it can be classified as black coffee; once milk is added, the flavor direction may evolve into a latte. This article will start from the basic concept of espresso, sort out its relationship with black coffee, and then break down the latte-making process step by step, including extraction parameters, milk foam handling, and latte art techniques, so coffee enthusiasts can replicate café-level output in their own kitchens.
The knowledge encompassed by coffee culture is quite rich, and coffee has all sorts of alternative names. The terms we casually use in daily conversation—espresso, latte, americano, cappuccino, and so on—Front Street Coffee wants to tell you that if no flavorings or extra ingredients are added and the cup contains only coffee from start to finish, then collectively calling them black coffee actually makes sense—after all, black coffee is essentially a single category: just grind the beans into powder and extract. But once something else is added, such as milk, the result might become a latte. Isn't coffee interesting? The content Front Street Coffee will share next revolves around the methods for making espresso and latte. Once you learn them, you can make yourself a cup of coffee to your liking at home anytime.
Espresso Belongs to Black Coffee
Espresso is a coffee category with a very strong flavor impact. It is made by forcing 92°C hot water under 9 bars of high pressure through extremely finely ground coffee powder to complete the extraction.
It originated in Italy, with a history dating back to the early 20th century. However, before the mid-1940s, this beverage relied purely on steam pressure for production. It was not until the spring-piston lever espresso machine was invented and successfully put into commercial application that espresso truly transformed into the form we are familiar with today.
In terms of texture, espresso is more viscous and heavy than drip coffee, and contains more soluble substances per unit volume; it is usually measured and served in "shots." The chemical composition of espresso is complex and easily changes, with many components decomposing due to oxidation or temperature drop.
How to Make a Latte
First, place the coffee cup on the warming area of the espresso machine, so that when extracting the espresso, the cup wall temperature is already at an ideal state.
Grind the dark-roasted coffee beans, put the coffee powder into the tamper, use the tamper to press the powder surface flat, then lock the tamper onto the espresso machine's extraction port and start extraction to get ESPRESSO. The extraction time depends on the actual tamping situation, usually fluctuating between 20 and 25 seconds, and the amount of extracted espresso is 30 milliliters.
If making a plain latte, you can add chocolate syrup to the extracted ESPRESSO. The specific amount can be adjusted according to personal taste; generally 6 to 8 milliliters is more suitable.
Take an appropriate amount of milk, place it under the steam nozzle of the espresso machine, and froth it into a mixture of hot milk and milk foam. Shake the mixture of milk and milk foam up and down to fully blend the milk foam and milk. Finally, pour the blended milk and milk foam evenly into the ESPRESSO while controlling the flow rate and doing latte art at the same time, and a cup of espresso latte is complete.
Latte is a classic combination of Italian espresso and milk, and Italians often treat latte as a breakfast drink. In the morning kitchens of Italians, coffee and milk are often boiling at the same time on the stove where sunlight can reach. Front Street Coffee feels that for Italians who love drinking lattes, rather than saying they are fond of Italian espresso, it would be better to say they are partial to milk, and only Espresso can make ordinary milk burst forth with an unforgettable flavor.
