Flavor description of raw coffee beans treated with red wine grinding scale of manor production area
Honey treatment (Miel Process in Spanish) is said to refer to the process of making raw beans by sun-drying with mucous membranes.
After the outer pulp of the coffee bean is removed, there will be a layer of sticky jelly. The traditional method of washing is to wash it off with clean water, but because of the limitation of water resources in some high-altitude areas, there is this way of direct drying.
The honey treatment process is vulnerable to pollution and mildew, so it needs to be closely watched throughout the process, constantly turning, and speeding up drying, so as to avoid bad fermentation flavor. Its advantage is that it can best preserve the original sweet flavor of coffee ripe fruit, making the coffee show elegant black sugar flavor and drupe flavor, while the berry flavor also supports the basic aroma of red wine, which is considered to be a very elegant product. The popularity of honey-treated boutique coffee beans is largely due to its sweet and thick characteristics. in recent years, there are more and more boutique coffee beans called "Miel Process", and they have also become the preferred material for international boutique coffee contestants.
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.
