Introduction of flavor characteristics of Robusta coffee beans introduction of varieties of Robusta coffee beans

Qianjie knows that there are many coffee lovers who can name the three major varieties of coffee-Arabica, Robusta, and Liberica. Among them, Arabica coffee accounts for more than 70% of global coffee production, while Robusta coffee beans with high production capacity account for only about 20%.

Robusta is mostly used in the production of instant coffee, which contains high caffeine, and the addition of acrylamide, a carcinogen in instant coffee, makes people even more disdainful of Robusta, which is used to make instant coffee. But existence is reasonable, and there must be a reason why Robusta has been in circulation for so many years.

Robusta coffee is a natural variety in West Africa. We often compare Arabica with Robusta, but this is not rigorous, because the two are not at all the same level in botany. Robusta actually belongs to the Canefa species, also known as the Congolese species, just as Ironka belongs to the Arabica species. But unfortunately, there is only one species called Robusta in the Canefra species that can be commercialized and well known, so that now Robusta has almost replaced Canefra as a synonym for the species.

The advantages of Robusta

As far as planting is concerned, Robusta coffee trees have the characteristics of high temperature resistance, cold resistance, drought resistance, moisture resistance, resistance to diseases and insect pests and strong adaptability, and can grow well in flat land and low altitude areas. Unfortunately, the coffee beans produced are lack of aroma. Strong bitterness (due to high caffeine) and lack of acidity, so it is mostly used for instant coffee, canned coffee, or brewed three-in-one coffee. Many coffee shops add an appropriate proportion of Robusta robusta beans to make espresso (Espresso) to deepen the "taste" (such as strong, rough, etc.) and increase the fat concentrate (crema).

Qianjie Coffee learned from the observation of Robusta raw beans that Robusta coffee beans are round in shape and have larger granules, and their caffeine content is nearly twice that of Arabica coffee beans. It is precisely because of the high caffeine content that caffeine has become a natural insect repellent that helps drive away most pests. In other words, Robusta coffee is relatively cheap and easier to grow.

Robusta is widely planted and can be seen in Vietnam, Brazil, India and other countries. Robusta coffee plants can be found even in Hainan and Fujian provinces of China.

The disadvantage of Robusta

Qianjie mentioned earlier that Robusta has higher levels of caffeine, amino acids and chlorogenic acid than Arabica coffee varieties. Among them, chlorogenic acid is the source of bitter taste, so Robusta's flavor is not as charming and elegant as Arabica, replaced by a more mellow, lower taste, as well as walnut, peanut, hazelnut, wheat, grain and other flavors. there will even be a pungent earthy smell.

It is precisely the poor flavor of Robusta coffee beans that is spurned by the boutique coffee industry, so it is often used as the raw material of instant coffee, or mixed with Arabica coffee beans to make Italian beans.

[the shape of Robusta coffee beans]

Robusta coffee beans are one fruit and one bean. After observation in the front street, it is found that the shape of Robusta is more round, showing a "C" shape; the middle line is in the shape of "I", and the color of raw beans is yellowish brown.

Commercial mixed beans

Blended coffee is also known as mixed coffee, that is, a variety of individual coffee is mixed together, so as to integrate and give full play to the strengths of a variety of individual coffee beans, blended beans from different areas of coffee beans mixed to make a more balanced taste.

There are also two types of coffee beans: first mix the beans and then bake them, which is called raw spelling; and roast and then mix the coffee beans, which is called cooked spelling.

In the front street coffee bean list, a single product of coffee beans is impossible to see the existence of Robota beans. But isn't there no Robusta coffee on the front street? No, Robota beans are found in the commercial beans of Qianjie Coffee for making espresso.

The commercial mix of front street coffee beans contains 30% of Colombian beans, 60% of Brazilian beans and 10% of Robusta beans.

In terms of the flavor of individual beans, the taste of coffee obtained from commercial beans is much lower than that of high-quality coffee beans. Generally, commercial beans are chosen to be used for blending. After mixing the beans, you can also make coffee with a good export flavor, which can be used to make lattes. Cabo and other espresso. And our commercial mix to make Espresso, because there are robusta beans, oil will be richer, taste classic, caramel sweet, nut and cocoa, dark chocolate flavor, sweet and sour balance, a little bittersweet, long-lasting.
