Which is true love, Espresso or freshly brewed coffee?

Historically, Italy was the first country in Europe to import coffee commercially, and now Italian coffee, especially espresso, the so-called soul of coffee, dominates the global market with lightning speed. What is the difference between Espresso and regular coffee?

1 What is Espresso? How is it different from regular coffee?

Espresso is a strong dark coffee made by a special extraction process. Its history is relatively short, but it has quickly become a favorite among coffee lovers in just a few years.

Espresso's production principle is actually very simple, nothing more than what people often say "9 atmospheres, 90 ° C, 30 seconds". But what exactly does this mean? In fact, this refers to the high temperature of 90 ° C and the high pressure environment of 9 atmospheres, which can extract a small amount but a high concentration of Espresso in just 30 seconds.

This new method of high temperature and high pressure extraction can penetrate into the coffee powder more than traditional methods, and the coffee powder used to make Espresso is generally more finely ground, so it can extract more of the internal components of the coffee powder, and its taste is naturally stronger.

2, coffee fat: Espresso is different from the typical characteristics of ordinary coffee

In addition to the strong taste and the small amount of coffee in a cup, Espresso has a typical feature that can be distinguished from ordinary freshly brewed coffee, which is the coffee fat floating on the surface of Espresso (Crema). So how did it come about?

It is often said that freshly ground coffee beans should be kept overnight. Why is that? In fact, this is because freshly roasted coffee beans contain too much carbon dioxide. If they are used to make coffee immediately after grinding, too many bubbles will hinder the extraction process.

Of course, in addition to the carbon dioxide that comes with the coffee powder itself, when the water suddenly returns to the normal pressure environment from the high pressure state, there is also a lot of carbon dioxide involved in the air. Therefore, from the production process of Espresso, when the extracted coffee flows out from the coffee machine, due to the change of air pressure, the liquid cannot carry the original carbon dioxide in the coffee powder and the air involved in the outflow, and many gases will gush out of the coffee surface to form a layer of foam.

3. What is the role of espresso coffee grease?

(1)Determine if coffee is fresh.

Usually, if a cup of Espresso is made with fresh coffee powder, it will have more coffee fat on the surface. And if the coffee fat doesn't look good, it's probably because the beans are too ripe.

However, it should be noted that some coffee beans will be placed in the packaging bag to absorb carbon dioxide deoxidant, so that the carbon dioxide content is less, the production of oil naturally less. Therefore, coffee oil cannot be used as the only standard for judging coffee quality.

(2)Judge coffee taste intensity

We can also know the taste intensity of coffee through coffee fat, usually the darker the color of coffee fat, the stronger the taste of Espresso.

(3)sealed fragrance

Because coffee oil completely covers the surface of Espresso, it can better seal the aroma of coffee in the cup.

What is the difference between Espresso and freshly brewed coffee?

Usually, Espresso can be obtained by mixing different types of coffee beans after fine grinding. Its acidity is generally not high, but the taste is very mellow and strong, and there is a certain sweetness to balance the bitter taste of coffee.

Espresso

Regular coffee takes a relatively long time to make, so the sourness and bitterness will be more obvious. Of course, the specific flavor is also related to factors such as the type of coffee beans. In addition, due to the lack of thorough extraction, the taste of freshly brewed coffee is not as strong as espresso coffee.

Espresso or freshly brewed coffee, which has more caffeine?

It is well known that coffee generally contains a certain amount of caffeine. Which coffee has more caffeine, Espresso or freshly brewed coffee?

It depends on which angle you look at the problem: freshly brewed coffee is definitely higher in caffeine per cup, because espresso cups are generally smaller. Espresso, however, has a stronger flavor, so it has significantly more caffeine in a given volume.

It is worth mentioning that because Espresso tastes very strong, the average person will not drink too much at a time; on the contrary, drinking ordinary freshly brewed coffee often does not pay attention to controlling the amount of drinking, so it is often easy to consume more caffeine.

Espresso or freshly brewed coffee, which is true love?

Although Espresso is called the soul of coffee, there is no saying that one process is better than another. As the saying goes, each cabbage has its own love, whether you drink Espresso or freshly brewed coffee is entirely up to you. In addition to different tastes of different people, different moods and drinking occasions or times will also have an impact on the coffee selected. (Text/The Kitchn)
