If coffee beans produce oil, can you still drink it?

Coffee bean oiling refers to the layer of oil that seeps out of the surface of coffee beans during the roasting process. This oil is called the essence of coffee beans, and it contains rich aroma and flavor substances. However, many people have doubts about whether coffee bean oiling affects the drinking experience.

First of all, we need to understand that the oiliness of coffee beans does not mean that they have gone bad. On the contrary, it is actually an important indicator of the freshness and quality of the coffee beans. When you buy freshly roasted coffee beans, you may see some tiny oil stains or gloss in the packaging bag.

Secondly, during the brewing process, this layer of surface oil will also dissolve in the water and combine with water molecules to form a rich aroma and taste. So even if you choose to use coffee beans with obvious surface oil to brew, there will not be much residue in the final cup.

However, not everyone likes to drink coffee with oil. For some people, this oily feeling may affect their taste and comfort of coffee. If you are one of them, you can choose to buy lighter roasted coffee beans because they usually produce less oil.

In addition, it is important to note that the oiliness of coffee beans does not mean that they have gone bad or expired. On the contrary, if properly stored, freshly roasted coffee beans can maintain their high-quality characteristics for weeks or even months.

In summary, although it is normal for coffee beans to produce oil and it will not have much impact on the drinking experience, if you don’t like coffee with surface oil, you can choose lighter roasted beans or try other processing methods (such as the follicle method) to reduce the amount of surface oil dissolved into the cup.
