The difference between espresso (Espresso) and single coffee

I. Introduction to the concept of espresso coffee and single-serve coffee.

Espresso: If you want to use data to explain it in a general way, it is that 7g of powder is extracted by 92 degrees of water at 9 atmospheres for 25 to 30 seconds to obtain 30 ml of coffee, which is called Espresso.

Single coffee: coffee made from only coffee beans from a single country or region, we call it single coffee.

2. Is single coffee espresso coffee?

Originally, Chen Lei thought that espresso coffee must be made with blended coffee beans to be considered espresso coffee, but in recent years, it has been found that the use of single coffee beans to make espresso coffee has gradually become a popular trend.

It also breaks my previous idea. In fact, it can be seen from the above concept that the coffee made by the espresso beans according to the espresso making method is also espresso coffee.

3. Is espresso coffee a single coffee?

It says that espresso coffee can be espresso coffee, so espresso coffee is espresso coffee? The answer is: not necessarily, this needs to be verified from two aspects. The type of coffee beans used. If the espresso obtained is made from single-serve coffee beans (e.g. Brazilian, colon, mantinin, etc.), Chen Lei believes that this espresso can also be called single-serve coffee.

If espresso coffee is made from blended coffee beans, Chen Lei believes that espresso coffee cannot be called single-serve coffee.

What is the essential difference between espresso and single-serve coffee?

Comparing the above three aspects, we conclude that espresso coffee can be single-serve coffee or not, and the difference between them is based on the coffee beans used.

Single coffee can be espresso or not espresso, and the two are divided according to the strength of the coffee solution. For example, Colombia beans made in a siphon pot are not espresso coffee, while Colombia beans made in a coffee machine are espresso coffee.
