Espresso is also widely recognized, and you can enjoy various types of espresso machines at home, such as mature manual models, fully automatic types and capsules that can be brewed more easily.

In addition to the machine that uses the capsule, you also need to prepare your own coffee beans. Which coffee beans are suitable for grinding?

Let's take a look at how to grind coffee beans suitable for espresso.

The function of espresso

The most popular coffee in Italy. In Italy, Caff è refers to espresso. A special machine is used to generate high vapor pressure, and hot water is instantly passed through the coffee powder to extract it.

High pressure causes coffee ingredients to condense and is fully mixed with oil to produce a bitter and round taste. Basically, use about 7 grams of beans and extract about 30 milliliters of beans in a short period of 20 to 30 seconds.

How to grind coffee beans suitable for espresso and matters needing attention

The grinding of coffee beans has different stages, from the finest to the finest, fine grinding, medium grinding, medium grinding, coarse grinding, etc., usually divided into 5 to 6 stages. The smaller the particle size, the stronger the bitterness, and the thicker the particle, the easier the acidity.

In addition, the characteristic of the concentration of the extracted coffee liquid is that the more detailed it is, the thicker it is, the more dilute it is.

Espresso is recommended for fine grinding

Espresso is a kind of coffee with a strong bitter taste, so "grinding" is appropriate because it can show its characteristics. In addition, fine grinding can make coffee bean ingredients easier to melt, even if the extraction time is short, you can also make espresso.

Pay attention to clogging coffee powder

However, even if ultra-fine grinding is said to be appropriate, if the grinding is too fine, the filter may clog and it may take more than 20 to 30 seconds to remove it. In addition, depending on the type of coffee beans, the coffee powder may become sticky and moist when it is finely ground, which can also lead to clogging.

In this case, it is necessary to polish it thicker, so it will take some time to extract and carefully check the state of the coffee liquid and determine whether it is appropriate.

Coffee machines that can be finely ground are expensive.

By the way, only a few factories can adjust to fine grinding, and the price is very high. Even if the current mill does not support ultra-fine grinding, try to grind it as fine as possible, because if it is too fine, some machines will be clogged.

If you can use coffee powder to fully extract the coffee powder and feel the taste, you may not need to buy more coffee. I think it's worth a try.

Grind coffee beans before making coffee

In addition to the size of the grain, the time spent grinding beans is also important. Grinding beans increases the surface area and the area exposed to oxygen, which makes it easier to oxidize. With the progress of oxidation, the flavor becomes worse, from literally "sour", you will no longer be able to enjoy the original taste of beans. Therefore, in order to prevent oxidation, coffee beans should be ground before brewing.

This applies to all extraction methods, but espresso is particularly ground, so it may have a larger surface area and oxidize faster, so please be careful.

Summary of the characteristics of "espresso" how to grind coffee beans

We found that the "fine grinding" method also plays a role in giving full play to the attractiveness of espresso, even in small amounts, which can enjoy rich bitterness and flavor.

It is no exaggeration to say that understanding the problems caused by ultra-fine grinding and adjusting the characteristics of your own machine or grinder is one of the secrets of brewing delicious espresso.
