Today's protagonist is Yega Xuefei, which is the most common in the sun and water, because the treatment is different, so the two cooking methods are not the same.

The difference between the appearance of sun-cured and washed coffee beans

Observe from silver skin

In the process of processing, the refined washing method usually removes the silver skin from the coffee beans, showing a special luster, but the dry and refined method (sun-drying method) only takes off the coffee shell, and the silver skin is still intact.

The difference between raw beans: generally washed raw beans are turquoise, while sun-washed raw beans are yellowish green.

If we roast and heat the coffee beans, the coffee beans processed by drying will peel off a lot of silver, while the coffee beans processed by washing will be much less.

When we look at the central concave line of coffee beans, if we retain a lot of white silver skin, the coffee beans processed by water shampoo are more likely.

Silver Skin/Chaff: there is a thinner film inside the parchment that wraps the coffee beans. Because the color is glossy and silvery, people used to call it "silver skin".

This layer of silver will fall off during baking. Usually when you grind the coffee, you find some silver crumbs in the coffee powder. These crumbs are the silver skins that fail to peel off the coffee beans during baking.

Cooked beans: there is more silver skin washed in water and less in the sun.

The outer silver skin of the beans in the sun is relatively more, and it takes off more thoroughly when baking, so it is relatively less when grinding; there is more silver skin in the beans washed in water, and there will be a lot of residue after baking and more when grinding. Of course, it is directly related to the baking degree. The deeper the baking, the cleaner the silver skin will take off.

If there is too much silver skin, it will taste astringent, but if the raw bean treats the silver skin too much, it will lead to a decrease in flavor.

Moreover, there must be silver skin on the central line of washed beans, but the problem is that that part may not produce obvious astringency, so don't pick out the silver skin completely.

The difference between dried incense:

Sun Yega Chuefei: light fermented wine, spices

Washed jasmine, lemon or lime acid

Referring to the parameters of coffee hand in front street, water temperature and degree of grinding, there are some differences:

[water washing Yega Fischer]: it is recommended to use 15 grams of powder at 92 degrees water temperature, grinding degree of small Fuji 3.5.The ratio of water to powder is 1: 15 and 15 V 60 filter cup, the ratio of water to powder is 1:14, the first water injection is 30g, steaming for 30s, the second water injection is 110g water cut off, the second water injection is 215g water, the water in the tail section is not needed, the extraction time is about 2Rd 05s.
