Professional coffee knowledge exchange More coffee bean information Please pay attention to coffee workshop (Weixin Official Accounts cafe_style)

Qianjie previously shared knowledge about sun treatment and washing treatment, so this article will compare the differences between the two different treatments. All know the difference between the flavor of the sun and the washing treatment, but that is the beans of different producing areas to compare, then the same coffee to do the comparison will have a more intuitive performance, interesting is not, then go with the front street!

Most solar treatments use African overhead sheds, which can effectively block moisture and soil from the ground and increase air convection. The temperature will also be strictly controlled during the sun exposure process, so as not to cause excessive fermentation due to high temperature. The whole process of solarization usually takes more than 20 days, so that the strains and coffee cherry pulp gradually ferment, so the flavor is sweet, but also with rich tropical fruit flavor.

The washing method is to put coffee cherries into water after picking, pick out the fruits with insufficient maturity by using the buoyancy of water, and then remove the peel/pulp of the berries with a peeling machine, and place them in a fermentation tank for one night to decompose and shed the pectin layer. After fermentation, the shelled beans will be washed in the channel for 30-60 minutes. Through the special channel and water flow washing, the beans with low specific gravity and poor quality can be removed, and then the high-quality coffee beans will be drained of water. Finally, they will be spread on the shelf to dry, and the target moisture content can be packaged and stored.

After harvesting, coffee beans must be immediately processed, otherwise they will start to ferment and cause coffee beans to produce odors. There are two methods of treatment: solarization and washing, which cause different flavors. The beans of solarization method have complete natural mellow flavor, gentle aroma and more colloid; washing method has good mellow flavor, high aroma and lively acidity. Compared with the solarization method, the washing method has better quality control. During the washing process, the defective beans floating on the water surface can be easily removed, and the flavor is not easy to appear. Because the fermentation time is short, the beans are completely stripped and washed in the sink. Therefore, the washing method will present a clean and flawless taste.

Take Yega Shefi for example. What is the difference in taste between washed and sun-dried Yega Shefi?

The washing and sunning of the yega-shefi cup test notes:

The difference between dry incense:

Sunburn Ye Jia Xue Fei: light fermentation wine fragrance, spice fragrance

Wash Ye Jia Sherfie: Jasmine flower fragrance, lemon or lime acid fragrance

[Soak coffee in a cup at a ratio of 8 grams of powder to 150 ml of 93 ° C hot water for 3-4 minutes until coffee grounds form]

Difference in taste:

Sunlight plus snow: Sunlight is a little complicated, light fermentation wine fragrance, burnt bitterness will be heavier, taste will be a lot richer, honey sweet, cocoa rhyme with a little spice, body thick and lasting aftertaste.

Washing Ye Jia Xue Fei: The acidity of washing treatment will be brighter, just like citric acid, taste more fragrant, citrus fragrance is more obvious, and there is some black tea feeling in the later stage.

Same: Both have fruit acid flavors, similar to lemons and citrus fruits.

[Manual data]

[Sunburn Ye Jia Xue Fei]: It is recommended to use 15 grams of powder at 89 ° C, small Fuji grinding degree 4, V60 filter cup, water powder ratio 1:15, first water injection 30g, stewing for 25s, second water injection 104 g water cut off, second water injection to 230g water, tail water do not, extraction time 2:12s;

[Washing Ye Jia Xue Fei]: It is recommended to use 15 grams of powder at 92 ° C, water powder ratio 1:15, V60 filter cup, water powder ratio 1:15, first water injection 30g, stewing 28s-30s, second water injection 110 g water cut off, second water injection to 230g water, no water at the end, extraction time 2:15s;

In this way, you can feel the comfort of the taste buds and nasal olfactory cells activated by Ye Jia Xue Fei just like flowers.

Every coffee growing area in the world has its own unique climate and production culture, and the quality of coffee depends on what treatment is used, if it is solarization, it is direct sunlight. However, if it is water washing, the treatment process is very different. Those "peeled" coffee is subjected to a honey-treated solarization process, while the washed coffee goes to a fermentation tank to remove residual pectin layers and substances. Careful monitoring ensures that the fermentation of the coffee beans is controlled and consistent. This is also why most of the fine coffee beans are washed.
