The road to coffee bean extraction: from source to aroma

introduction

Coffee, one of the most popular drinks in the world, has a delicate and complex process behind it - the extraction of coffee beans. From planting to picking, processing to roasting, each link has an important impact on the final aroma and taste of coffee. This article will take you into this magical and delicious journey.

Planting and harvesting

The birth of a high-quality coffee bean begins when it is cultivated at high altitudes. These areas usually have a cool climate, plenty of sunshine, and nutrient-rich and well-ventilated soil. Farmers patiently wait for the fruit on the tree to ripen, and when the fruit turns from green to red, it is harvest time.

Peel removal and fermentation

The picked coffee cherries are washed and then sent to the peeling machine, where the outer skin is peeled off. Next, the pulp with two seeds (i.e. coffee beans) inside is retained and sent to the fermentation tank along with the pectin. During the fermentation process, the pectin breaks down and produces unique chemical changes, giving the coffee beans a richer flavor.

Wash and dry naturally

After fermentation is complete, the coffee beans need to be washed to remove residues. There are usually two methods for this step: water washing and natural drying. The water washing method soaks the coffee beans in water and uses mechanical force to remove the pulp and pectin; while the natural drying method spreads the coffee beans out in the sun for several days. Each method has its own characteristics and has different effects on the final taste.

Filter and sort

After washing and drying, the coffee beans will go through the screening and sorting process. This step is to grade the coffee beans according to factors such as size, shape, density, etc., and remove inferior or damaged particles. Only high-quality coffee beans that pass strict screening can enter the next key step - roasting.

Baking and blending

Roasting is one of the most influential steps in the coffee bean extraction process. By controlling the temperature and time, the moisture and chemicals inside the coffee beans are transformed to produce specific flavors and aromas. Different degrees of roasting will bring completely different taste experiences, from light roasting to dark roasting, each has its fans.

Grinding and Brewing

After careful preparation, the coffee beans need to be ground carefully and accurately. This step takes into account both the brewing method (such as drip, espresso, etc.) and the desired coarseness according to personal taste preferences. Then, add the coffee powder to boiling water and brew it to enjoy delicious coffee full of aroma and flavor.

Conclusion

Whether it is from planting to the end of the final cup of mellow taste, the entire coffee bean extraction process requires many steps, and each step has an important impact on the final product. By understanding the extraction path of coffee beans, we can better appreciate and taste this wonderful drink.
