Coffee beans: the heart of coffee processing

Types of coffee beans

The core of coffee processing is coffee beans, and coffee beans come in many different varieties. The two most common varieties are Arabica and Robusta. Arabica beans are generally considered high-quality and high-value options because they have lower acidity and bitterness and a rich and complex taste. Robusta beans are easier to cultivate and contain higher levels of caffeine, so they are often used to make strong and intense coffee.

From fruit to green beans

During the processing, the fruits with moderate maturity and bright red or yellow color need to be picked first. Then these fruits are peeled and pulped to obtain the two little elves wrapped inside - green beans. These green beans also need to go through fermentation, cleaning, drying and other steps to reach the appropriate moisture content and maintain their original characteristics.

Roasting: releasing aroma and flavor

Roasting is one of the key steps in coffee processing. It not only gives coffee beans their unique aroma and flavor, but also changes their color and shape. During the roasting process, coffee beans undergo a series of chemical reactions, including water evaporation, reduced acidity, increased bitterness, etc. Different degrees of roasting will produce coffee with different tastes and flavors.

Grinding: Unleash the vitality of coffee powder

In order to make delicious coffee drinks, the roasted beans need to be finely crushed into powder. This process is called grinding. By adjusting the coarseness to suit different types of brewing methods (such as drip, soaking, etc.), you can control the extraction time and extract the ideal taste and flavor.

Brewing: Enjoy the perfect cup

The last step is the brewing process, in which we will mix the processed and ground coffee beans with water using boiling water or other liquids. In this process, the hot water will dissolve the chemicals in the coffee beans and release the aroma and flavor. Through different brewing methods (such as drip, soaking, espresso, etc.), coffee drinks with different tastes and flavors can be produced.

Conclusion

Coffee processing involves multiple steps from planting to brewing. Each step has an important impact on the quality of the final cup. Understanding these processes and mastering the corresponding skills can help us better appreciate and enjoy a cup of delicious coffee.
