What are the characteristics of Robusta coffee beans?

Recently, a friend came to ask if there are any Luodou in Qianjie. I'd like to taste it. It turned out that when he was reading coffee books, he saw a description of the flavor of Luodou and thought it was very interesting, so he wanted to give it a try.

Of course, there are Luodou in the front street, but it is generally not easy to take it out, because according to the law, every time Luodou is sacrificed, a guest will be lost (joking). In front of the street, let's briefly talk about what Luo Dou is. Luodou is Robusta, this kind of coffee beans and Arabica coffee beans almost contract people's coffee consumption, of course, in the field of boutique coffee, it is mainly Arabica, you can hardly see Luodou, so if you want to taste 100% Luodou in a shop that sells hand-brewed coffee. Robusta is not a valuable coffee bean. in the futures market, its price is just over half that of Arabica coffee beans. However, because it is relatively rare in coffee shops, it is a novel coffee bean for those who like high-quality coffee.

In this regard, Qianjie intends to brew Luodou by hand and describe its flavor to everyone. The Luodou in Qianjie is from Vietnam, which is the world's largest producer of Luodou, and coffee production accounts for about 20% of the world's total coffee bean production. First, let's take a look at the characteristics of Luodou in appearance. The middle line of Luodou is "1-shaped". The baked beans are swollen and full, like small steamed buns. Dry fragrance is generally the smell of spices, baked nuts and baked bread.

The Luodou in the front street uses deep roasting, so the hand flushing parameters use the method of deep roasting coffee beans. Filter cup: Kono filter cup powder quantity: 15g grinding degree: medium coarse (20 sieve pass rate 70%) powder to water ratio: 1:15 water temperature: 87 degrees water injection method is divided into three stages of water injection, the first stage is injected with 30ml water for 30 seconds, the steam exhaust effect of this bean is very good.

The second stage of clockwise circle water injection 100ml, as far as possible to raise the silt layer, and then wait for a slight drop in the water level to continue the third stage of water injection, the same clockwise circle water injection 95ml, to achieve the total water injection 225ml. After the coffee liquid of the filter cup is filtered, the extraction is finished for 2 minutes and 20 seconds.

First, let's smell the wet fragrance, the aroma is not obvious, it smells like hazelnut and caramel. When tasting, the first feeling is that there is not too much taste, will not be very bitter, but the taste of grain is very heavy, a little like the very rich mugi-cha, the taste is relatively rich, the taste is also relatively thick. The flavor performance at this stage is not brilliant, and it is not bad, so keep to the rules! When you taste the coffee again in the medium and low temperature stage, the first smell of rubber will come to the nostrils, and then the taste of the grain will be heavier, the cleanliness will be lower, and the tail rhyme will have a fishy, bitter taste.

The flavor of Robusta coffee beans is not flattering, because the sources of bitterness such as chlorogenic acid and caffeine in Robusta are higher than those in Arabica, which is still the same. Robusta is naturally more bitter than Arabica. And Robusta is generally planted below 800 meters above sea level, and its cleanliness and flavor are naturally not as good as those grown in Arabica at high elevations. Of course, there are some better quality Luodou, the flavor of this kind of Luodou will be cleaner, but the main flavor is peanut butter, walnut, hazelnut, wheat, caramel and so on. Of course, Luodou also has advantages, such as Luodou has higher caffeine and rich fat, which can provide mellow taste. Luodou may not have the desired flavor when used alone, so the Luodou in front street is used to match with Arabica. This coffee bean is an Italian commercial mix in front street, using 10% Robusta made from Brazil and Arabica of Colombia. Make espresso that can enrich the oily taste without losing the flavor. Finally, if you really want to try 100% Luodou, you can go to some department stores with international zones, and there will be some imported coffee beans on the shelves. Qianjie bought a bag of Vietnamese Zhongyuan No.1 Luodou a few years ago, and when it was opened, it was greasy and milky (it was later found out that condensed milk and sugar were added to the roast). It smelled very good. The espresso oil extracted is very thick and delicate, and everything is very beautiful, until after a mouthful of boredom, it is shocking and hits the heart. You have to experience it.
