The world of coffee: a journey of expertise

The origin of coffee

Coffee is a drink that originated in Africa and is said to have been first discovered in Ethiopia. According to legend, a shepherd noticed that his sheep became particularly active after eating a red fruit. So he tried the fruit and found that it could keep people awake and energetic. This is the origin of coffee.

Coffee bean processing

To make delicious and mellow coffee, you first need to process the beans. First, the ripe coffee berries are peeled, and then the inner part called the "germ" is taken out and dried. Next, the germ is roasted at high temperature until it turns black, and different degrees of roasting produce different tastes and flavors.

Different regions produce different flavors

Factors such as climate, soil and cultivation methods around the world affect the flavor characteristics of coffee beans. For example, the Brazilian region is famous for its soft and rich coffee with nutty and chocolate flavors. The Colombian region is loved for its high acidity and refreshing taste. The Kenyan region is highly regarded for its strong fruit acidity and rich berry aroma.

Different roasting levels bring different flavors

In addition to regional factors, the degree of roasting is also an important factor affecting the flavor of coffee. Light roasting usually retains more of the characteristics of the original beans, with obvious acidity and floral aroma. Medium roasting will reduce the acidity and add some nutty or chocolate-like taste. Dark roasting will make the coffee beans more bitter and give them a rich and heavy taste.

The brewing method has a great influence on the quality

Brewing method is one of the most effective ways to bring coffee grounds into contact with water and extract the nutrients and flavor characteristics. Different brewing methods can bring completely different coffee experiences. For example, coffee brewed in a French press usually has a heavier taste and oily texture, while hand brewing can better show the delicate flavor of the coffee beans.

Professional knowledge improves quality

To become a coffee expert, you need to master a lot of professional knowledge. It is essential to understand the impact of different origins, roasting degrees and brewing methods on quality. In addition, you also need to learn how to cup and how to adjust parameters such as grind size and water temperature to optimize the brewing process.
