Explore espresso, coffee types and how it’s made

Abstract: This article explores the types and production principles of Italian espresso. Italian espresso is a form of coffee made by quickly extracting coffee powder through high-pressure steam. Different types of coffee beans and roasting levels affect the taste and aroma of coffee. In the production process, it is necessary to master key factors such as the correct grinding degree, powder amount, water pressure and temperature. This article deeply analyzes the production principles of Italian espresso and provides readers with guidance on making delicious Italian espresso.

In the world of coffee, espresso occupies an indispensable position with its unique rich taste and charming aroma, but do you know the types of espresso and how it is made? Let's explore this topic in depth.

1. Types of espresso

1. Single espresso : This is the most basic form of espresso, usually made from a single coffee bean. It has a strong taste and low acidity, making it suitable for direct drinking or as a base.

2. Double Espresso : As the name suggests, double espresso is made with twice the amount of single espresso. Its taste is stronger and suitable for people who like strong flavors.

3. Cappuccino Espresso : This is a drink made with equal proportions of espresso and milk. It has a rich taste, with both the richness of coffee and the smoothness of milk.

4. Latte Espresso : Compared with cappuccino espresso, latte espresso has a lower proportion of coffee and is mainly a fusion of milk foam and coffee, with a softer taste.

Each espresso has its own unique taste and flavor, but at their core is the charm that comes from the production principles of Italian coffee machines.

2. The production principle of espresso

The principle of making espresso seems simple, but it actually contains a rich combination of scientific principles and techniques.

1. Selection and grinding of coffee beans : Italian espresso has extremely high requirements for coffee beans. Usually, you need to choose coffee beans with full grains, dark brown color, and rich aroma. When grinding, you must also choose the appropriate grinding degree according to the type of coffee machine to ensure the coffee extraction effect.

2. High-pressure and high-temperature extraction : The espresso machine uses high pressure and high temperature to allow hot water to quickly pass through compacted coffee powder in a short period of time, thereby extracting high-concentration coffee. This extraction method allows the oil and aroma in the espresso to be fully released.

3. Influence of coffee machine structure : The structure of the espresso machine, especially the design of the inner tank of the coffee machine, has a crucial impact on the extraction effect. Reasonable structural design can ensure that hot water forms a uniform flow rate when passing through the coffee powder, thereby improving the extraction efficiency.

4. Temperature maintenance and control : During the extraction process, temperature maintenance and control is also key. Too high or too low temperature will affect the taste and aroma of the coffee. The right temperature can ensure that the coffee presents the best flavor during the extraction process.

The process of making espresso is not only the application of technology, but also an art that requires constant practice, adjustment and exploration. Behind every kind of espresso lies the ingenuity and passion of the maker.

From single to double shots, from cappuccino to latte, each espresso has its own unique charm and story, and the production principles behind it allow us to have a deeper understanding and appreciation of this charm. Next time when you taste espresso, you might as well think about the skills and principles behind it, which may give you a deeper understanding of coffee.
