Coffee tanning treatment, washing, taste and flavor advantages processing process

The process of washing taste and flavor price of coffee in the sun

Water washing is the most popular treatment method at present, and most boutique coffee beans will choose water washing method. Washing coffee refining process: harvesting → storage tank (removal of impurities and immature beans) → pulp removal machine (removal of pulp and impurities) → fermentation tank (removal of mucous membrane on endocarp) → washing pool (selection of light and hard beans) → sun drying field (or dryer) → sheller (removal of endocarp) → grading (electronic bean selector or hand selection, (screen, etc.) the appearance of coffee beans washed and processed at → export is relatively neat. And there are few 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 taste in the process of fermentation. 50 grams of fermented beans will be spoiled by semi-water washing, also known as "honey treatment", which is a compromise between drying and water washing, eliminating the link of water-washing fermentation of coffee fruit. Harvest → storage tank (remove impurities and unripe beans) → pulp removal machine (remove pulp and impurities) → washing pool (select light and hard beans) → sun field (or dryer) → sheller (removal of endocarp) → classification (electronic bean selector or hand selection, sieve, etc.) → outlet

The sun method depends entirely on the weather, and the dryness of coffee fruit is difficult to control. If the sun is not clean, it is easy to mix with impurities. In the process of the sun, the pulp of the coffee fruit has not been removed, so it is often moldy and rotten. Therefore, in the view of many people, the quality of sun-exposed coffee beans is not controllable and the level is not too high.

Advantages

Except for the first step of using water to filter out inferior beans, the other steps no longer need any water, and can be used repeatedly. In areas where water resources are not abundant, this method is simply awesome.

And because sun-dried beans have irreplaceable special flavor, some excellent farms begin to take sun-dried beans seriously, such as putting them on shelves to prevent pollution and fine selection, so today we can see a lot of high-quality sun-dried coffee beans.

Flavor

Although the sun-cured beans are uneven in appearance and different in color, because the coffee beans ripen naturally inside the fruit and are not disturbed by the external environment, the sun-cured coffee beans have a stronger flavor, wine-like fermented taste and sweet taste.
