You may have heard a saying: Sun-dried coffee beans taste richer, washed coffee beans are cleaner and more acidic. Is that true?

Coffee beans will have what kind of flavor, in fact, you can see some clues from the way coffee beans are processed.

Today, let's imagine how coffee tastes from the process!

First of all, we must first clarify a concept: processing process = fermentation process.

Coffee bean processing is the process of picking coffee cherries from fruit trees and processing them into pre-roasted beans. This process can also be seen as the fermentation process of coffee beans. Just like wine needs to be brewed well to produce excellent flavor wine, the processing method is similar to raw beans. It is a combination of fermentation of strains and coffee beans, which can guide the hidden secret flavor of coffee beans.

● So what kind of secret flavor will the sun and water washing method have?

The sun method, simply put, is to use the sun to dry coffee cherries with pulp and peel, so English is called Nature, but this nature treatment method seems easy but not simple, and his refinement has also gone through some effort.

Commercial sunburn treatment is to spread a piece of plastic cloth on the ground and put the coffee beans directly on it for sunburn; however, this problem will lie in the heat transfer and the thermal convection instability of coffee cherries. If they are not stirred frequently, there may be problems of excessive heating or uneven fermentation. (It is conceivable that the beans spread on the top are very comfortable, and the beans that are trapped below may smell strange).

In addition, there are many bad strains and pollution on the ground, which will also destroy the flavor of coffee beans. So traditional sunning, there's a lot of... Flavor, early good beans will not use the sun method to process, because we have a bad impression, the price is not high.

However, in recent years, the sun method has improved a lot. Most of the current solarization methods use African elevated sheds, which can effectively block moisture and soil on the ground and increase air convection. The temperature will also be strictly controlled during the sun exposure process, so as not to cause excessive fermentation due to high temperature.

The whole process of solarization usually takes more than 20 days, so that the strains and coffee cherry pulp gradually ferment, so the flavor is sweet, but also with rich tropical fruit flavor.

The washing method is to remove the peel and pulp of the harvested coffee cherries, and throw the remaining seeds and a layer of residual mucosa into a sink for fermentation with water. The entire fermentation time is only about 24-30 hours.

Compared with the solarization method, the washing method has better quality control. In the process of washing, the defective beans floating on the water surface can be easily removed, and the flavor is not easy to appear. Because the fermentation time is short, the beans are completely stripped and washed in the sink. Therefore, the washing method will present a clean and flawless taste.

● In fact, the washing method can also be subdivided into machine drying in the later stage, or drying in the later stage. Different regions will also develop unique washing methods, such as Kenyan 72-hour washing method. Let's briefly introduce it first!:

Kenyan washing

Kenyan coffee is famous for its rich layering and clean taste. Its unique Kenyan washing method, after two washing and fermentation procedures, commonly known as "double fermentation", is a rather complicated but delicate green bean treatment method; this treatment method is more time-consuming and water consuming than the general washing method, so Kenya coffee is more expensive, but it is also an indispensable method to create Kenya coffee's unique sour flavor and clean taste.

First washing and fermentation

After harvesting coffee cherries, they will first pass through the proportion of water flow to pick beans; the principle is to use the density and quality difference of coffee fruits themselves to make selection; coffee beans with high density (heavy quality) will sink into water, while coffee beans with low density will float. Ripe, high-quality coffee fruits have a high density and are selected for further processing.

After selecting good quality and ripe fruits, peel them off and soak them in water to ferment the pectin mucus attached to the outer layer of raw beans. Pectin has natural sugars and alcohols that are crucial to coffee sweetness development, acidity and overall flavor.

Fermentation time up to 24 hours, fermentation can remove 80- 90% of pectin, leaving only the flavor of coffee beans.

Second washing and fermentation

Then enter the second washing fermentation process. After the coffee beans in the previous stage are cleaned, they are soaked in water for 12- 24 hours. This process increases protein and amino acids, and the acidity of the coffee bean thus creates a complex, delicate texture.

Finally, remove all remaining pectin and move the beans to a high shelf for sun drying, depending on the weather conditions, usually about 5- 10 days to complete.

However, in general, washed beans will have high quality and bright fruit acid, flavor is also very clean, sometimes washing method can highlight the special flavor of coffee beans themselves oh.

So how does the treatment affect the flavor of coffee beans, get to the point?

The answer is: fermentation time and fermentation degree

Sunlight method, because beans will be exposed to the sun together with the peel and pulp, the degree of fermentation is higher, and the time is longer, usually can develop more tropical fruit flavor.

Washing method, leaving only a thin layer of mucosa, the overall processing time is also shorter, even if Kenya's 72 hours washing method, and the sun drying time is also a lot worse, so you can imagine that the general washing of beans, flavor is cleaner
