It seems that when everyone tastes espresso, they are pursuing the perfect coffee fat (crema)-the brown foam that floats on freshly brewed espresso. The right coffee fat has become synonymous with a good cup of coffee, but this layer contains a deeper coffee principle.

What is coffee oil (Crema) ●?

Coffee grease is a layer of coffee foam with rich taste and aroma floating on coffee. To put it simply, the high temperature and high pressure in the brewing process combines the air with the soluble fat in the coffee, and the coffee oil is produced. Some people will call this phenomenon the Guinness effect phenomenon because it has a very similar foam layer to the famous Irish black beer (stout).

An espresso with a clearly visible coffee fat requires good quality, moderately ground coffee beans and a skilled barista. Compared with dripping coffee drip coffee, coffee oil gives espresso a more saturated flavor and a stronger finish.

What is the perfect coffee fat for ●?

Each barista has his own idea of the definition of perfect coffee fat. But at the very least: when brewing an espresso, the coffee fat on it should not be too thin or too thick, and it can be kept in a state for about two minutes.

It's a bit complicated to flush out beautiful coffee grease because there are too many factors that affect the results. However, there are several main points that can be followed in practice:

1. Too much coffee oil will reduce the total amount of espresso. Many baristas pursue a coffee fat ratio of about 1/10 of the whole cup of coffee.

2. Both excessive extraction and insufficient extraction will affect the formation of coffee oil.

3. If the coffee oil defoams within a minute, it means that the extraction time is too short, or the roasting degree of coffee beans is too shallow.

Generally speaking, a good espresso machine takes about 15 to 30 seconds to extract espresso, but each machine is different.

5. Remember to warm the machine before brewing coffee and clean the machine regularly to ensure the quality of operation. A dirty coffee will add bitterness and miscellaneous flavor to the coffee it brews.

Factors affecting the formation of Coffee Oil by ●

In fact, it is difficult to fully master coffee fat, because in addition to the technology that practice makes perfect, it can also be affected by the following reasons:

How fresh are the coffee beans used for brewing?

Fresh coffee beans produce more coffee fat because they still release soluble fat. Try to observe that if neighboring coffee shops use self-baked beans, the espresso brewed from their own baking shops may have thicker coffee fat than other shops that do not use self-baked beans. This is the importance of fresh baking.

The roasting degree of coffee beans will also affect

Generally speaking, after the second explosion stage of roasting, the deeper the roasting degree, the less coffee oil. Because a large amount of coffee oil has been released during roasting, coupled with stirring, packaging and grinding, coffee oil will be more worn out after oxidation. In addition, the amount of fat in coffee beans that are too lightly roasted and not fully reacted is not ideal. As a result, many coffee makers offer products that are roasted at a specific degree and specially used to boil espresso to ensure that coffee beans have enough oil.

The handling of coffee beans should also be taken into consideration.

Coffee beans dried by the natural sun can usually flush out the best coffee oil because sun beans have higher oil content and more storage.

Household Italian coffee machine brewing is also one of the factors.

Many household machines have the function of one-click operation and automatic brewing, which is very convenient, but compared with semi-automatic brewing operation, automatic setting will also limit the production of coffee oil. In order to make up for this deficiency, some machines will flush out the mimic coffee oil separately.

Is ● coffee fat really important?

Although that soft layer of coffee grease seems to be a prerequisite for a good espresso, it is not so absolute. Coffee oil does add more flavor to espresso, and drinkers also expect to enjoy the visual feast brought by this luxury foam when drinking coffee, but in fact, a cup of espresso without rich coffee oil can also be rich and delicious, with aroma overflowing-for example, SOE, which is becoming more and more popular in recent years, often does not have very rich and gorgeous coffee oil because of its baking degree, but it still does not damage its delicacy.

After all, coffee is for the satisfaction of taste buds. If there is no coffee oil on the coffee, please don't be depressed or disappointed that you didn't make a good cup of coffee. As long as it tastes satisfactory, it is good coffee. Keep in mind that the quality of beans, the degree of baking, processing technology and machine quality determine the final product, these elements can not escape the taste test.

For many people, coffee has become a necessity. Whether it is mental or physical habits, you need to immerse yourself in the charm of this dark drink at some point in the day. Behind these cups of drinks, there are many unknown small details. After understanding the coffee oil, the next time you drink espresso, you can experience this brown foam more carefully. will it feel different again?
