Which beans contain more oil? Explore the oil content of coffee beans!

Coffee is one of the most popular drinks in the world, and the amount of oil produced by coffee beans plays an important role in determining the taste and flavor of coffee. So, which beans contain more oil? Let's explore.

First of all, it is important to understand that the oil contained in coffee beans mainly comes from internal fat. Coffee beans of different types and origins will have different oil yields. For example, Arabica coffee beans produce relatively little oil, while Robusta coffee beans are more likely to release a lot of oil.

Secondly, the roasting process will also affect the amount of oil produced by coffee beans. As the temperature gradually rises during the roasting process, the internal fat begins to melt and gradually releases from the surface to form a smooth and shiny "skin" with aroma and flavor characteristics. This "skin" is what we often call "peanut kernel", which is responsible for the rich aroma, rich taste, and long aftertaste in the cup.

In addition, the degree of roasting of coffee beans will also affect the amount of oil. Generally speaking, the deeper the roasting, the higher the oil content in the coffee beans. Lightly roasted coffee beans usually have a drier surface and relatively less oil, while dark roasted coffee beans have a smooth surface and a certain degree of oil exudation.

Finally, you can also see the oil release of coffee beans during the brewing process. When brewing with water, the high temperature water will further dissolve the residual internal fat in the coffee beans and release it into the cup to form "floating foam". These "floating foams" not only give the coffee aroma and taste more layers, but also form beautiful, artistic and visual enjoyment on the wall of the cup.

In summary, the amount of oil in coffee beans depends mainly on two factors: the type and origin, and the degree of roasting. Arabica and Robusta are the two most common and popular coffee beans on the market, and they differ in the amount of oil they produce. In addition, the degree of roasting will also affect the amount of oil produced by coffee beans. Therefore, when choosing and brewing coffee, we can choose coffee beans of different types and roasting degrees according to our personal taste preferences.
