What are water-washed sunny coffee beans?

Semi-washing method, also known as wet stripping or wet planing. Different from other treatments, the coffee beans are not directly dried to a moisture content of 11 murmur12%, but when the moisture content is about 30-35%, the surface hard shell is removed and the surface of the raw beans is directly exposed, and then continue drying until the moisture content is non-perishable and easy to store, and this secondary drying gives the coffee beans a swampy dark green appearance. Coffee beans treated with semi-washing have lower acidity and thicker characteristics.

The biggest difference in washing sun-dried coffee beans

The flavor of semi-washed coffee is between sun-washing and water-washing. This method is popular in Indonesia. Mantenin uses more semi-washing methods, and Brazil has also begun to use semi-washing methods in recent years.

The semi-washing method is similar to the water washing method, first removing the outer skin and part of the pulp of the coffee cherry berries, then drying the berries, making the berries dry and then moistening them, and then using a special machine to grind off the pulp and remove the seeds.

Remove the shell

After the end of the sun, the outer layer of the coffee seed has been dry and hard, at this time, the shell is removed by the sheller, that is, the treatment step of the sun method is completed.

Advantages:

Tanning method does not need water except for the steps of removing floating beans, and a bucket of water can be reused with low cost, so it is widely used in areas where water resources are not abundant and less affluent.

Disadvantages:

1. Sunburn method because the coffee beans must be placed outside, so there are often a lot of dead branches and leaves and other impurities mixed with it.

two。 Because it is the use of the sun's energy, the degree of dryness of coffee beans is not easy to control, resulting in coffee fruit "overdrying" situation, internal coffee beans are damaged as a result.

3. In the process of the sun, because the pulp has not been removed, it is often moldy and rotten.

Flavor:

Because the sun drying method is to let the coffee fruit dry naturally, the coffee beans can ripen naturally inside the fruit and will not be disturbed by the external environment, so the coffee beans treated by the sun method will enlarge their own flavor, mellow and strong flavor. and give off a sweet taste.

Washing method

Is to remove the peel and pulp of the screened coffee fruit through the shelling machine, and the remaining coffee beans containing pectin layer will be fermented for 12 to 24 hours by the symbiotic bacteria of the coffee itself, such as acetic acid bacteria and lactic acid bacteria. These strains will digest the pectin layer outside the coffee beans, and then the acid will seep into the coffee beans, making the flavor of the coffee beans sour, and then treated by water washing, so it is called water washing.
