Coffee bean display: unique taste, mellow black magic

Coffee beans are seeds from the coffee tree that are roasted and ground into our favorite drink. They are known for their unique taste and black magic. Here we will introduce this fascinating food from three aspects: the origin, production process and taste characteristics of coffee beans.

First of all, coffee beans originated in Africa, and are said to have been first discovered in the Ethiopian Plateau. Today, coffee trees are grown in dozens of countries around the world, and each region produces coffee beans with different flavor characteristics. For example, Brazil produces a large amount of high-quality and balanced Brazil Bourbon; Colombia is famous for its smooth and layered Colombia Yirgacheffe; Kenya produces Kenya AA with rich fruity aroma and obvious acidity. The unique and irresistible coffee beans produced in these different regions provide us with a rich and diverse choice.

Secondly, coffee beans need to be roasted and ground before they can be made into delicious coffee. Roasting is a key step that not only changes the color and shape of the coffee beans, but also affects their taste and flavor. Light roasting retains more of the original flavor, with obvious acidity and floral and fruity aroma; medium roasting reduces acidity, increases sweetness, and brings a certain degree of cocoa or nut aroma; deep roasting further reduces acidity, increases bitterness, and gives a rich and deep chocolate or caramel aroma. Before use, the coffee beans need to be crushed into particles of the size required for the brewing method.

Finally, when tasting a cup of high-quality coffee, we can experience its unique taste characteristics. High-quality coffee usually has a strong and complex taste, exuding a rich, long-lasting, and endless aftertaste on the tip of the tongue. The taste of coffee can be divided into four aspects: acidity, sweetness, bitterness, and mouthfeel. Acidity refers to the brightness and freshness that coffee brings on the tip of the tongue, which can enhance the layering of coffee; sweetness gives people a pleasant and rich feeling, making the coffee more balanced; bitterness is caused by the chemical reaction produced during the roasting process, and the right amount of bitterness can increase complexity; and mouthfeel includes the texture and heaviness of coffee in the mouth.
