Coffee, that beverage that awakens the senses and accompanies moments, has behind it a complex and fascinating production process. From the cultivation of its beans to the moment it is served in our cup, coffee travels a long road full of dedication and passion. This journey begins in the fertile lands of the coffee growing regions and ends in the delight of our palate, covering key stages that define its quality and flavor.
1. The Cultivation of Coffee
It all begins in the coffee plantations, where two main species are cultivated: Arabica and Robusta. The choice of species depends on several factors, including altitude, climate and soil type. Arabica, with a milder and more aromatic flavor, thrives at higher altitudes, while Robusta, stronger and with a higher caffeine content, adapts well to hot and humid climates.
Coffee needs a tropical climate, with stable temperatures between 15 and 24 degrees Celsius and abundant rainfall. The planting process begins with the sowing of seeds in nurseries. After several months, the young seedlings are moved to open fields where they will grow for the next 3 to 4 years before they begin to produce fruit.
2. The Harvest
Coffee harvesting is mostly manual, especially in mountainous terrain where mechanization is difficult. This process is carried out once a year, although in some countries there can be main and secondary harvests. The selection of the beans at the right point of maturity is crucial; the fruits must be red and firm, indicating that they are ready to be picked.
3. Coffee Processing
After harvesting, coffee must be processed quickly to prevent fermentation. There are two main methods: dry and wet. The dry method, the most traditional, involves drying the whole fruits in the sun before threshing to extract the beans. The wet method, on the other hand, removes the pulp from the fruit before drying the beans, which requires less time and produces a higher quality coffee.
4. Drying
Regardless of the processing method, the coffee beans should be dried until they reach a moisture content of 11%. This can be done in the sun, in drying patios, or with drying machines. Uniform drying is essential to avoid the proliferation of fungi and to ensure the quality of the coffee.
5. Roasting
Roasting is where coffee acquires its characteristic flavor and aroma. This process involves heating the green beans to temperatures between 180 and 240 degrees Celsius. During roasting, the beans undergo chemical changes, expanding and changing color to brown. The duration and temperature of roasting varies according to the desired flavor, from light to dark roasted.
6. Milling
Milling is the process of grinding roasted beans to prepare them for extraction. The size of the grind affects the surface area exposed to water and, therefore, the extraction of flavors. A fine grind is ideal for fast extraction methods such as espresso, while a coarse grind is used for slower methods such as French press.
7. Extraction and Service
Finally, the ground coffee is subjected to extraction, the process of passing hot water through the coffee to obtain the beverage. The temperature of the water, the contact time and the extraction method (drip, French press, espresso, among others) play a crucial role in the final profile of the coffee. Once extracted, the coffee is ready to be served and enjoyed, closing the cycle of its production.
This journey from bean to cup reveals the complexity and art behind each cup of coffee. From the careful cultivation and selection to the meticulous roasting and grinding process, each step contributes to the unique characteristics we appreciate in coffee. So, the next time we enjoy this beverage, let us remember the extensive process that has allowed that aroma and flavor to reach us.
