How to choose coffee beans? Explore the mystery of oil!

Coffee is a must-have drink for many people every morning, and choosing a good coffee bean is the key to making delicious coffee. When choosing coffee beans, exploring the mystery of oil can help us find the beans that best suit our taste.

First, you need to understand the difference in oil content between different types of coffee beans. Generally speaking, the deep roasting process releases the oil inside the coffee beans and covers the surface to form a smooth and shiny appearance. These oils are also called "surface oils", which give deep roasted coffee a rich and bitter taste.

Secondly, you can judge whether the coffee beans contain enough oil by touching and observing when buying. High-quality fresh roasting can retain more surface oil soon and give people a soft, smooth and moist feeling. On the contrary, if you find that the beans you choose to buy look dry and dull, they may have passed their shelf life or are low-quality coffee beans.

Another thing to consider when choosing coffee beans is their origin and type. Coffee beans from different regions and varieties have unique flavor characteristics. For example, Arabica coffee from Brazil usually has a rich and mellow taste, while Yirgacheffe coffee from Ethiopia has a strong and floral flavor.

Finally, when choosing coffee beans, you should decide based on your personal taste preferences. If you like a strong, bitter taste and prefer a dark roast style, then choosing beans with more surface oil and darker color will be more suitable. On the contrary, if you prefer a more acidic, fresh taste and tend to prefer a medium or light roast style, you should choose beans with less surface oil and lighter color.

In short, exploring the secrets of oils when buying coffee beans can help us find the beans that best suit our taste. By touching and observing the appearance of coffee beans, understanding their origin and type, and choosing according to personal taste preferences, we can make a cup of delicious coffee that meets our needs.
