How Is Coffee Made: The 3 Essentials Processing Methods

How Is Coffee Made

How Is Coffee Made? Coffee is a familiar part of our daily routine that we often overlook. However, it’s important to recognize the journey that each coffee bean undergoes before reaching our cup. From its origin to the hands it passes through and the various processes it undergoes, every step contributes to the final product we enjoy. By understanding the journey of coffee, we can develop a deeper appreciation for our next cup and savor it all the more.

Growing Coffee: From Seed To Plant

The journey of coffee begins with the cultivation of coffee plants. Coffee is grown on flowering shrubs that were originally native to tropical Asia and Africa but are now cultivated worldwide. These plants thrive in specific climates near the equator, which collectively form the coffee belt. Adequate sunlight, frost-free conditions, abundant rainfall, and well-draining soil are essential for successful coffee cultivation. Other factors such as mineral-rich soils, high elevation, and consistent day-to-night temperatures contribute to the production of high-quality coffee.

There are two primary types of coffee: Arabica and Robusta. Arabica beans are considered superior, known for their sweeter and more complex flavors, but they are more challenging to grow and come at a higher price. On the other hand, Robusta beans have a bolder flavor profile and higher caffeine content, making them more resilient to adverse growing conditions. Both types of coffee beans have their unique place in the coffee industry.

Coffee plants bear fruits called coffee cherries. Within each coffee cherry, there are typically two coffee beans, although occasionally a single coffee bean called a peaberry can develop.

Processing Coffee: From Plant To Green Coffee Bean

The next step in coffee production is coffee processing, which involves separating the coffee beans from the coffee cherries and drying them. This process results in green coffee beans that can be stored until they are ready for roasting.

Here is a tabular representation of the coffee journey from cherry to cup:

Stage Description
Coffee Cherry The coffee cherry is the fruit of the coffee plant, containing the coffee beans.
Processing The process of removing the coffee beans from the cherry and drying them, resulting in green coffee beans.
Roasting The process of heating the green coffee beans to transform them into brown coffee beans.
Brewing The process of preparing the roasted coffee beans to extract their flavors and aromas, resulting in a cup of coffee.


How Is Coffee Made? Processing Methods

There are three main methods used in processing coffee:

1. Natural Processing: Also known as dry processing, this is the traditional method where coffee cherries are left to ferment in the sun. The fruity pulp is later removed, and the beans absorb sugars from the fruit during the process. Naturally processed coffees often have a sweeter taste. However, this method requires careful attention as the cherries can rot if not tended to properly.

2. Washed Processing: Also referred to as wet method or wet processing, this method involves removing the fruit from the beans before fermentation. The result is a more consistent and cleaner-tasting coffee. However, managing wastewater from this process can present environmental challenges. When done properly, washed coffees can have pure intrinsic flavors derived from the coffee bean itself.

3. Honey Processing: This method is a combination of natural and washed processing. The cherry is only partially removed before fermentation and drying. The resulting coffee is both sweet and clean in flavor.

Roasting Coffee

Roasting is the process that gives coffee its recognizable rich brown color. It also enhances the solubility of the coffee, allowing you to extract its flavors when brewing. Additionally, roasting adds its own distinct flavors to the coffee.

The flavor profile of a coffee roast depends on the time and temperature of the roasting process. Light roasts retain the origin flavors, with bright fruit and floral notes. Medium roasts develop some caramelization flavors from the roast. Dark roasts derive much of their character from the roasting process, showcasing toasted flavor notes and a full-bodied profile.

Brewing and Extraction

There are numerous methods for brewing coffee, with new ones constantly emerging. However, the fundamental purpose of all brewing methods remains the same.

Brewing involves extracting the soluble flavor compounds from the coffee beans into hot water. To facilitate this extraction, the coffee beans are ground. The fineness of the grind affects the extraction rate, with finer grounds allowing for quicker extraction. For instance, finely ground coffee is used for pulling espresso shots, while a medium grind is suitable for pour-over methods, and a coarse grind is preferred for slower methods like French press or cold brew.
