Wine-flavor sun treatment does not refer to the addition of red wine in the process of raw bean treatment, but its fermentation method and degree is similar to that of red wine, the treatment step is similar to the sun treatment, but the fermentation time is longer, the steps are as follows:

1. After picking ripe red fruits, coffee farmers put them directly in the sun field and dry them in the sun.

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

3. Dry after a few days

4. Remove the pulp and peel of the dried raw beans with a shelling machine, and take out the raw beans.

Advantages: wine-scented coffee beans have a higher rate of ripe red fruit and longer fermentation time than ordinary sun-cured coffee beans, thus increasing the sweetness of coffee, rich layering, and taste similar to the fermented flavor of red wine.

Disadvantages: this treatment is labor-intensive and time-consuming, so it cannot be mass-produced, so it is generally used to deal with some of the more expensive coffee beans.
