The secret of why coffee beans are called coffee beans is revealed. The secrets from planting to cup are fully analyzed

The birth of coffee beans and their global spread

The story of coffee beans begins in ancient Ethiopia, where the legendary discoverer of coffee was a shepherd named Kaldi. He found that his goats became extremely excited after eating a red fruit. Kaldi brought these fruits to the monks in the monastery, and after trying them, the monks found that the drink made from these fruits could refresh the mind. Initially, these fruits were called "coffee berries", and the use of coffee gradually became popular in the Arab world.

In the 15th century, coffee beans began to be widely planted and used in Yemen, an Arab country. Coffee not only became a daily drink here, but also used as part of religious ceremonies. With the development of trade, the cultivation and drinking habits of coffee gradually spread to the Middle East, North Africa and Europe. In the 17th century, coffee became a fashionable drink in Europe, coffee houses began to flourish in cities, and coffee culture began to influence Western society.

In the process of global dissemination, coffee beans have been given different cultural meanings and titles. In India, coffee is often called "coffee bean water", while in Japan, coffee culture has been integrated with the traditional spirit of the tea ceremony to form a unique way of drinking.

Botanical classification and characteristics of coffee beans

Coffee beans come from the coffee tree, a plant in the Rubiaceae family. The coffee tree's scientific name is *Coffea*, and there are two main economically important varieties: Arabica (Coffea arabica) and Robusta (Coffea canephora). Arabica coffee trees are more delicate and grow at higher altitudes, and their beans are usually complex in flavor and higher in acidity, while Robusta coffee trees are more heat-resistant and adapted to lower altitudes, and their beans have a stronger bitter taste and higher caffeine content.

The process of coffee bean formation begins with the pollination of the flowers of the coffee tree. After the coffee flowers are pollinated, they transform into green fruits, which are coffee cherries. When ripe, these fruits turn red or purple and contain two seeds, which are the coffee beans we know as coffee beans. During the processing, the skin of the coffee cherry is removed, and the remaining seeds are dried, shelled, and finally become the coffee beans we use.

Different varieties of coffee trees have a significant impact on the characteristics of the beans. For example, Arabica beans have a more prominent acidity and aroma, suitable for making specialty coffee; while Robusta beans are widely used in espresso and instant coffee due to their strong bitterness and high caffeine content. Understanding the characteristics of these varieties can help us better choose the right coffee beans to meet different taste requirements.

Why are coffee beans called 'beans'?

The reason why coffee beans are called "beans" is due to linguistic usage. In botany, the word "bean" usually refers to the seeds of legumes, such as soybeans or black beans. Although coffee beans do not belong to the legume family, their shape and appearance are similar to the seeds of these legumes, so they are also called "beans" in the language. This naming method reflects people's intuitive understanding of coffee seeds rather than their actual plant classification.

In the early history of coffee, people had limited knowledge of coffee beans, and many terms were based on the existing plant naming system. The appearance of coffee seeds is similar to that of seeds of legumes, which are flat and of a certain size, so the name "bean" was naturally given to coffee seeds. This usage is similar in different languages, for example, "coffee bean" in English also reflects a similar naming habit.

In addition, the word "bean" has the meaning of seed in many cultures. This commonality in language makes the name of coffee beans widely accepted and passed down. Although coffee beans have no direct relationship with beans in the traditional sense, this idiom has helped different cultures to recognize and accept coffee.

Coffee beans from planting to harvesting

The growing process of coffee beans has a crucial impact on their final quality. Coffee trees need to grow in a warm climate, with an ideal temperature range of 15 to 24 degrees Celsius, as well as sufficient rainfall and good drainage. Coffee trees are usually grown at high altitudes, which allows the coffee beans to better develop complex flavor characteristics.

During the planting stage, coffee trees need to be fertilized and pruned regularly to promote healthy growth and increase yields. Fertilization usually uses organic fertilizers to keep the soil nutrient balance. Pruning helps control the shape of the coffee tree and ensure that sunlight can evenly reach every part, which is essential for the ripening of beans.

The harvesting of coffee beans is usually divided into two methods: manual picking and mechanical picking. Manual picking can select ripe fruits, thus ensuring the quality of the beans. Mechanical picking is suitable for large-scale planting, but it may mix in unripe or overripe fruits, thus affecting the final quality of the beans. Harvested coffee cherries need to be processed as soon as possible to prevent the fruits from fermenting or rotting, which is directly related to the flavor and aroma of the coffee beans.

Every step from planting to harvesting has a profound impact on the flavor of coffee beans. Climate conditions, soil quality, and processing methods can all affect the acidity, sweetness, and flavor complexity of the beans, so understanding these processes will help you appreciate and select high-quality coffee.

Key steps in coffee bean processing and their impact on flavor

After being picked, coffee beans need to go through a series of processing steps before they can become roasted beans. These steps include peeling, airing, drying and shelling, each of which has an important impact on the flavor and characteristics of the beans. First, the coffee cherries need to be peeled after being picked. This process removes the outer skin of the fruit and only retains the seeds inside. The peeling method can be wet or dry, and the wet method usually better preserves the flavor of the beans.

After the skin is removed, the coffee beans need to be dried to remove excess moisture. The drying process can be done in the sun or in a dryer, which can prevent mold and ensure that the beans are evenly dried. The degree of drying directly affects the taste of the coffee beans. Over-drying will make the beans bitter, while too high humidity may cause mold.

Next, the coffee beans need to be shelled, which means removing the inner skin that surrounds the seeds. This step helps improve the quality of the coffee beans and makes them more uniform when roasted. The shelled coffee beans are called "green beans" and they still need to be further screened and graded before roasting to remove defective beans.

Each processing step affects the flavor of the coffee beans. For example, wet processing usually brings out a fresher acidic taste, while dry processing may retain more fruity aromas. Understanding these processing steps can help consumers better understand

The multiple roles of coffee beans in modern society

In modern society, coffee beans are not only a daily consumer product, but also play an important role in the economic, cultural and social fields. From an economic perspective, coffee is the second most traded commodity in the world, second only to oil. Its production and sales involve the livelihoods of millions of people, and every link, from growers to roasters to retailers, has a profound impact on economic development.

Culturally, coffee has become a cultural symbol of many countries and regions. In Italy, coffee culture is closely linked to daily life. Cafés are not only providers of beverages, but also important places for social interaction.
