How to quickly tell the difference between Robusta and Arabica?

In today's coffee consumption market, we can see three major coffee varieties, of which Alabia Arabica and Robusta Robusta occupy the most, while Liberia is relatively rare. When the coffee beans have not yet been roasted, we can quickly distinguish Adou and Luodou by special diagnosis of their appearance. Arabica coffee beans are long oval, flat, with S-shaped or C-shaped midline, while Robusta coffee beans are oval, spherical or nearly spherical, and the midline is straight.

But if you mix baked Robusta and Arabica together, it's not easy to tell them apart. So whether there are Luodou in a bag of coffee, we usually combine the taste and aroma to tell.

Most Luodou use deep baking, usually with ultra-high alcohol thickness, low bitterness, low acidity, flavor to walnut, peanut, hazelnut, mugi-cha, grain-based. When not handled properly, there will be a strong irritating earthy smell, such as rubber-like negative taste. This also makes everyone sum up as "Luodou flavor". Therefore, Luodou is mostly used as the formula of deep-roasted espresso, which is helpful to improve the consistency of espresso oil during extraction. For example, the commercial matching launched in Qianjie contains 10.

% of Luodou.

As the most popular variety on the market, all kinds of Arabica subvarieties will form unique and rich aroma and sweet and sour flavor according to the local conditions of the growing environment, especially high altitude, volcanic soil and microclimate, and the soft taste is more acceptable. Arabica usually shows floral and elegant flavors, reminiscent of flowers, fruits, chocolates, baked hazelnuts, etc., with a higher cleanliness.

Arabica is the most popular variety in the market, all kinds of sub-varieties will form a unique and rich aroma and sweet and sour flavor according to the local conditions of the growing environment, especially high altitude, volcanic soil and microclimate, and the soft taste is more acceptable.

When we analyze the substances contained in Robusta and Arabica, we can find that Arabica has almost twice as much sucrose as Luodou. Sucrose is converted into aromatic substances during baking, making the coffee more fragrant and sweet. With the continuous promotion of boutique coffee culture, people have higher requirements for the taste, taste and quality of coffee, so aroma-diverse Arabica beans are more in line with the high demand of the current boutique coffee market than Robusta. For example, the rosy summer coffee in front of Panama has a unique fragrant orange honey rhyme, which makes the taster feel as if he is drinking a cup of fruit tea.

Compared with Arabica, the Robusta variety has a higher caffeine content, about 2.7% Mel 4%, twice as much as Arabica. As a natural pesticide of plants, caffeine can be protected from most insects.

From the planting point of view, Robusta coffee tree can withstand high temperature, cold, drought and humidity. In addition, the fruit yield of a single plant of Robusta is also very high, and it has a strong ability to adapt to the environment. It can generally be planted in low-altitude plains, and it can be directly managed and picked by machine, and the price is naturally cheaper. Therefore, the production cost of Robusta planting is lower, and it is more suitable for commercial mass production.

Although Arabica is liked by more people, it does not mean that it has no shortcomings. Arabica's plants are very "picky" about their growing environment.

Arabica is more vulnerable to pests because of its low caffeine content, so it needs to be planted above 800 meters without frost. The higher the altitude, the formation of a significant temperature difference, more conducive to the accumulation of coffee fruit flavor substances, aroma development will be more full. If you want to show a variety of positive flavor, in addition to high altitude, but also need to have a unique microclimate blessing, many well-known boutique coffee are produced in the microclimate. The terrain at high altitude is often uneven, and it is more difficult to plant, manage and pick, so high-quality Arabica coffee requires more production costs.
