Coffee beans knowledge revealed: from origin to roasting, a comprehensive explanation of the story of coffee beans!

Coffee beans are an indispensable part of our daily life, but do you know their story? From origin to roasting, coffee beans go through a delicate and complex process. Let's unveil the mystery of coffee beans together.

First, let's look at where coffee beans come from. There are three main producing regions in the world: Latin America, Africa, and Asia. Each producing region has its own unique climate and soil conditions, which directly affect the taste and flavor of coffee beans. For example, Latin America is generally known for its soft and balanced taste; Africa is known for its high acidity, rich floral and fruity flavors; Asia is mostly characterized by low acidity and a strong taste.

Next comes the harvesting and processing stage. When the coffee trees bear ripe red berries, farmers will pick these ripe berries by hand and process them initially. The most common methods are wet or dry processing. Wet processing requires separating the pulp from the seeds, and then fermenting the seeds in water. This process can make the coffee beans cleaner and softer in taste. Dry processing, on the other hand, dries the whole fruit and then removes the pulp. This method usually produces some natural sweetness and fruity aroma.

The last key step is roasting. Roasting is to heat the raw coffee beans to a high temperature, which changes their internal structure and releases rich aroma and flavor. Different degrees of roasting will produce different taste characteristics: light roasting usually has a bright, high acidity and light flavor; medium roasting has a balanced and rich taste; deep roasting brings a strong, bitter but powerful flavor.

In summary, coffee beans go through three main stages from origin to harvesting and processing to finally being carefully roasted. Each stage has an important impact on the quality and taste of the final product. Therefore, when tasting a cup of delicious coffee, please remember the story behind it and experience the wonders in it.
