Description of Flavor of Coffee Bean Red Wine by Solar treatment

The color of raw beans treated by drying is yellow, and the water content of coffee beans is generally about 11%, 12%. The advantage is that sun beans have better sweetness and mellow thickness, and less sour taste, so many coffee fans like it very much. The disadvantage is that due to the use of artificial and natural treatment methods in the process, the beans of the sun method do not look good in appearance, the quality is not good-looking, and the coffee beans processed by washing will have greater ups and downs. The appearance of coffee beans is neat, and there are fewer impurities and defective beans, and the water content of coffee beans is generally about 16%. The advantage is that it has less miscellaneous flavor, clear taste and bright sour taste; the biggest disadvantage is that coffee beans are easy to get sour and astringent during fermentation, and a fermented bean will spoil 50 grams of beans

The traditional treatment method is difficult to control the changeable fermentation degree of coffee beans. But red wine treatment rules can ensure the quality of coffee beans by controlling PH value, even temperature and humidity, and airtight fermentation makes aroma less volatile.

Next, let's talk about the specific process of fermentation. First of all, Colombian farmers carefully pick coffee cherries and carefully select coffee red fruits to ensure that among the coffee cherries selected for processing, the percentage of immature cherries is less than 2%, defective beans less than 3%, and floating beans less than 5%.

The selected coffee cherries are placed in a specific container by the farmer's uncle, which should have a device similar to a red wine fermentation suppository or a single exhaust valve. In this way, carbon dioxide can be spilled through the device to control the concentration of air in the container. At this time, the coffee cherries in the container are fermented with acetic acid, and the beans are relatively bright, clean and citric acid.

In general, the processor injects carbon dioxide into the container to prevent oxidation from producing volatile acid. this process is called lactic acid fermentation, which produces malic acid and stone acid, which is relatively stable, so the beans fermented by lactic acid are more sour, with cheese, nutty and creamy flavor.

Do you feel surprised by this process? have you ever tasted the coffee made by this method?
