Professional barista communication, please pay attention to coffee workshop (Weixin Official Accounts qianjieccoffee)

Sun-drying is the most traditional method of processing. The fruits are naturally sun-dried after harvest. The steps are as follows:

1. After harvesting, coffee farmers are placed directly in the sun field and dried by sunlight;

2. During the exposure process, it is necessary to stir in time to avoid uneven drying or fermentation;

3. After a few days, it will be dried;

4. Remove the pulp and pericarp of the dried raw beans with a shelling machine and take the raw beans.

Advantages: The coffee fruit treated by the sun treatment method retains its pectin during treatment, and the pectin itself is sweet. During the sun treatment process, the sugar will be converted into coffee beans, so the processed coffee will be relatively sweet, rich in taste and strong in layering.

Disadvantages: there will be more defective beans, beans appearance is not uniform, easy to absorb the smell of the ground and soil (now many are used to avoid contact with the ground).

Wine fragrance solarization treatment method, than "solarization treatment method" more "wine fragrance" two words. Is alcohol involved in this process? The answer is no, this method does not refer to the addition of red wine in the processing of raw beans, but its fermentation method and degree are similar to the fermentation of red wine. The processing steps are similar to the sun treatment method, but the fermentation time is longer, so it is called it. The procedure is as follows:

1, coffee farmers harvest mature red fruit, directly placed in the sun field, sun exposure drying;

2. The degree of fermentation will be continuously tested during the exposure process.

Advantages: the aroma of the sun coffee beans than ordinary sun coffee beans mature red fruit rate is higher, fermentation time is longer, so increase the sweetness of coffee, layered feeling is more rich, taste similar to red wine fermentation flavor.

Disadvantages: This method of processing costs labor and time, so it cannot be mass produced, so it is generally used to process some more expensive coffee beans.
