Introduction to the steps of Qianjie-Solar treatment process

We should know what flavor coffee beans will have, and the handling of coffee beans is the main influencing factor. How to imagine the flavor of coffee from the processing process? First of all, it is necessary to clarify a concept: treatment process = fermentation process.

The treatment of coffee beans is the process of picking coffee cherries from fruit trees and turning them into raw beans before baking. This process can also be regarded as the process of coffee bean fermentation. Just as wine needs to be well brewed to produce wine with excellent flavor, the method of treatment is similar to that of raw beans, which is a combination of bacteria and coffee beans, which can lead to the hidden flavor of coffee beans!

So what kind of secret flavor will there be between tanning and washing?

To put it simply, the sun is used to dry coffee cherries with pulp and peel, so it is called Nature in English, but this nature treatment seems easy but not simple, and it has also made some efforts.

The way to deal with the commercial sun is to spread a piece of plastic cloth on the ground and put the coffee beans directly on it for the sun; however, the problem will lie in the transfer of geothermal heat and the unstable heat convection of coffee cherries, if not stirred frequently, there may be problems of excessive heating or uneven fermentation. You can imagine that the beans laid on the top are very comfortable in the sun, and the beans stuffed at the bottom may smell funny.

In addition, there are many bad bacteria and pollution on the ground, which will also destroy the flavor of coffee beans. So the traditional sun, there are a lot of flavor, early good beans will not use the sun method to deal with, because everyone's impression is very bad, the price is not high.

However, the solarization method has made great progress in recent years. Most of the current solarization methods use African-style viaducts, which can effectively block moisture and soil on the ground and increase air convection. In the process of sun exposure, the temperature will also be strictly controlled to prevent the high temperature from causing excessive fermentation.

The whole process of sun treatment usually takes more than 20 days, allowing the bacteria and coffee cherry pulp to gradually ferment, so the flavor is relatively sweet, but also with rich tropical fruit flavor.

In short: Qianjie is a coffee research hall, happy to share the knowledge about coffee with you, we share unreservedly just to make more friends fall in love with coffee, and there will be three low-discount coffee activities every month. The reason is that Qianjie wants to make more friends drink the best coffee at the lowest price, which has been Qianjie's tenet for 6 years!
