People love coffee more and more, and slowly understand coffee more and more deeply, from only paying attention to coffee bean packaging to coffee bean varieties, and then to paying attention to the treatment of coffee beans, which is a process of slowly accumulating coffee knowledge. In this article, Qianjie Coffee will share the relevant knowledge about the treatment of raw coffee beans.

If you often come to Qianjie coffee, you will find that there are many kinds of Qianjie coffee, among which these coffee beans come from more than 50 different producing areas. In addition, baristas on Qianjie often make coffee beans that are not on the shelves and share them with each other. Among these beans, the most are washed and sun-treated, and there are some anaerobic sun-treated coffee beans that are rarely heard of.

The anaerobic fermentation mentioned in Qianjie Coffee is a very popular post-processing method in recent years, usually putting the coffee fruit in an airtight container or in a washing tank to ferment in water. In this process, different microbes are used to ferment to produce a special flavor, and after the fermentation is completed, the coffee fruit is taken to the sun to dry. The main features of this method are:

1. The coffee fruit is placed in a stainless steel container (which will not absorb the previous coffee bean flavor) to make the flavor cleaner.

two。 Fermentation in a closed environment, various factors are easier to control, each treatment of coffee beans tend to be more consistent, and the aromatic substances are not easy to volatilize.

3. Fermentation in an oxygen-free environment, the flavor is more round, easy to have cheese, cream aroma.

4. The coffee bean flavor using this method usually has a fuller mellow thickness and wine aroma.

One of the reasons why Qianjie coffee is seldom used in anaerobic sun treatment is that when this coffee bean is on the shelf, Qianjie coffee will go through several rounds of necessary procedures such as roasting plan adjustment and cup test brewing. If this coffee bean is not special, Qianjie Coffee will establish a file about the beans, but will not be on the shelves.

So every bean on the front street coffee shelves has a reason. Although there are fewer coffee beans in anaerobic sun treatment than in water-washed sun beans, Qianjie coffee still has anaerobic sun beans on the shelves. Coffee beans from Colombia, for example, are treated with anaerobic sun treatment.

Qianjie Coffee this moonlight coffee bean comes from Estogatine Farm in Huilan area, which is the most famous boutique coffee producing area in Colombia. Huilan coffee is generally grown on the slopes of the canyon, with high altitude and high-quality climate type, Rain Water is abundant. Qianjie coffee cup tested many kinds of coffee beans from Huilan producing area, and agreed that the coffee beans in Huilan producing area have full taste and heavy texture. It has nutty, chocolate, caramel and other aromas and supple pleasant acidity.

And this anaerobic sun-treated Huayue Night coffee beans have also undergone a corresponding cup test process. Qianjie baristas use the 200ml standard cup to test the bowl, using the 20th standard sieve with a grinding rate of 70% Mel. 75%, powder content 11.3g, water temperature 94 degrees Celsius, first grind to smell dry fragrance, the dry aroma of Huayue Night coffee beans exudes fermented wine flavor and chocolate flavor, and then fill the bowl with water to confirm the wet fragrance. After 4 minutes, the residue was broken and the flavor was identified. The wet fragrance smells of strawberry jam. The next step is to hand-flush and confirm this coffee bean once again.

Qianjie Coffee uses a filter cup: hario v60, grind degree: BG#6m (the size of fine granulated sugar), coffee powder / water ratio of 1:15. The water temperature is 90-91 degrees. The method of brewing and cooking is the three-stage extraction method, which is most commonly used in Qianjie coffee shop and is more suitable for beginners.

In the first stage, 30 grams of water is injected for 30 seconds, followed by 95 grams (about 125 grams indicated by the electronic scale). The injection is completed in about 1 minute, and the remaining 100 grams are injected at 3 places in the powder layer when the water level drops to 2 grams (about 225 grams shown by the electronic scale). About 1 minute and 40 seconds. 2 minutes-2 minutes 10 seconds drip filtration is completed, remove the filter cup, complete the extraction. Floral flavor: intense strawberry aroma, acidity of imported strawberries, mid-jam sweetness, slight cocoa tail, juicy taste.

You will find that coffee beans treated with anaerobic sun will have a stronger flavor and a higher thickness of fermented wine than those treated with water or sun treatment. In addition to this moonlight night, Qianjie Coffee also has a coffee bean from Costa Rican Monster Manor, which is also treated by anaerobic sun treatment. Qianjie Coffee also tested it and found that its dry aroma has a very strong cinnamon flavor, while the wet fragrance not only has a strong cinnamon flavor, but also has the sweetness of caramel. Then Qianjie coffee brewed it, sure enough, with a very strong cinnamon flavor, caramel, gingerbread flavor, so Qianjie coffee also jokingly called this coffee bean from the monster manor Christmas coffee beans.

It seems that the treatment of coffee is also one of the important reasons that affect the flavor of coffee beans, so we can start from here when buying coffee beans. Qianjie Coffee believes that washing treatment can maximize the origin characteristics, variety characteristics and sour taste of coffee. In addition, washing treatment first remove the pulp and then dry the beans, which can reduce the risk of coffee beans making mistakes. In the case of sun treatment, the coffee fruit is first dried with the coffee peel and pulp, and the taste of the coffee fruit will enter the beans during the drying process, rather than being washed off like washing. The flavor brought by the sun treatment is very unique, which is more mellow than the fruit of washed beans, with reduced acidity and sweetness at the same time.

Therefore, the flavor brought by each kind of processed beans is different, and we can choose according to the taste of our own coffee.
