Coffee Beans Plant Origin and Extraction Process

Coffee beans come from a plant called coffee tree, which belongs to the Rubiaceae family. The coffee tree is an evergreen shrub that grows mainly in tropical and subtropical regions. There are many varieties of coffee trees, but the two most common are Arabica (Coffea arabica) and Robusta (Coffea canephora). Arabica coffee trees grow at higher altitudes and produce beans with a more complex flavor, while Robusta is adapted to lower altitudes and produces beans with a stronger flavor.

The growing environment of coffee beans requires a warm and humid climate, with a suitable temperature range of 15 to 24 degrees Celsius, and the soil needs to be rich in organic matter and well-drained. When the coffee tree matures, it will produce red or purple fruits, which are called coffee cherries.

The process of extracting coffee beans from the fruit of the coffee tree is quite complicated. First, the ripe coffee cherries need to be picked by hand or harvested mechanically. Next, the cherries are shelled to remove the outer pulp and membrane, leaving only the coffee beans. The coffee beans are then washed, dried and roasted to become the coffee powder we know as coffee.

Ideal conditions for growing coffee trees and how they affect flavor

Coffee trees have strict requirements for their growing environment, mainly including climate, soil type and altitude. First of all, coffee trees grow best in tropical climates, especially warm and humid conditions. The ideal temperature range is 15 to 24 degrees Celsius. Too high or too low temperatures will affect the development of coffee beans.

Soil type also has a significant impact on the growth of coffee trees. Coffee trees prefer acidic soils that are rich in organic matter and well-drained. This type of soil provides the necessary nutrients to ensure the healthy growth of coffee beans. If the soil is too alkaline or poorly drained, coffee trees may suffer from root diseases or slow growth.

Altitude is an important factor affecting the quality of coffee beans. Generally speaking, coffee trees in higher altitude areas grow more slowly, and the flavor substances in the beans are more abundant. Therefore, coffee beans produced in high altitude areas are more delicious.

Detailed explanation of the planting and picking process of coffee beans

The coffee bean planting process starts with sowing. First, you need to select suitable seeds and grow seedlings in a warm and humid environment. Coffee seedlings need sufficient sunlight and stable humidity during their growth, and are usually cultivated in a greenhouse or shaded place. When planting, the seedlings are transplanted into the prepared fields, and the spacing needs to be moderate to ensure sufficient light and air circulation.

The growth cycle of coffee trees is long, and it usually takes three to four years from sowing to the first fruiting. During this period, coffee trees need regular fertilization and irrigation to ensure their healthy growth and effective prevention and control of pests and diseases. As time goes by, coffee trees gradually enter the fruiting period, and coffee cherries begin to mature on the trees.

Picking coffee beans is a critical process, which is usually divided into two methods: manual picking and mechanical picking. Manual picking is more precise, and the pickers can select ripe cherries to ensure the quality of each coffee bean. Mechanical picking is suitable for large-scale planting, but it may pick unripe cherries together. In order to ensure the quality of the beans, the picked coffee cherries need to be strictly screened and processed to remove defective beans and unripe beans.

Coffee bean processing and its impact on flavor

After being picked, coffee beans need to go through a series of processing steps before they can become the final coffee powder. The first is the shelling stage, which removes the outer skin and pulp of the coffee cherry, leaving only the raw coffee bean at the core. Shelling can be done by wet processing or dry processing, of which wet processing usually better preserves the flavor of the beans.

Next comes the washing process, which aims to remove impurities and pulp residues on the surface of the beans. The washed coffee beans will enter the drying stage, which can be dried naturally or mechanically. This step is crucial to ensure the quality of the beans, because excessive or insufficient drying may affect the flavor of the coffee beans.

Finally, the coffee beans need to be roasted, which is a key step in affecting the flavor of the coffee.

Global coffee production and its market impact

The main coffee producing countries are located in tropical regions, with Brazil and Vietnam being the world's largest coffee producers. Brazilian coffee beans are known for their balanced flavor and nutty aroma, and mainly produce Arabica beans. Vietnam is dominated by Robusta beans, which usually have a stronger bitter taste and higher caffeine content.

In Africa, Ethiopia is known as the birthplace of coffee, and its beans are famous for their complex flavor and rich fruity aroma. Kenyan coffee beans are favored for their high acidity and distinct fruity flavor. These unique flavor characteristics make them competitive in the global market.

Colombia and Guatemala in Central America are also important coffee producers. Colombian coffee beans are admired for their balanced flavor and sweet and sour taste, while Guatemalan beans are known for their rich chocolate and smoky flavors. Coffee beans from these regions usually have a high-quality flavor and are deeply loved by coffee lovers.

Coffee beans from these different regions have their own characteristics due to their unique growing conditions and processing methods, which influence the flavor trends and supply chain of the global coffee market. The diversity of producing countries not only enriches the choice of global coffee, but also promotes the innovation of various flavors in the market.

The cultural value and economic impact of coffee beans

Coffee beans are not only an important cash crop worldwide, but also a symbol of many cultures. In many countries, coffee is not only a daily drink, but also an important medium for social activities and cultural exchanges. For example, in Italy, coffee culture is deeply rooted in social life, and espresso is almost a daily necessity. In Ethiopia, the coffee ceremony is a traditional social activity that reflects the local people's respect and love for coffee.

Economically, the coffee industry’s contribution to the global economy cannot be underestimated. Coffee is one of the world’s most important traded commodities, second only to oil. Millions of farmers around the world rely on coffee cultivation for their livelihoods, and the upstream and downstream of the coffee industry chain, including production, processing, transportation and retail, also create huge value for the global economy. Especially in developing countries, coffee cultivation and trade provide important economic support for many communities.

In addition, the global circulation of coffee beans has promoted cultural exchanges and economic development. Consumers in different countries have different preferences for coffee beans.
