Follow the caf é (Wechat official account vdailycom) and found that Beautiful Cafe opened a small shop of its own.

It is not difficult to distinguish between Arabica beans and Robota beans. You can easily tell the difference between Arabica beans and Robota beans by their appearance. The former is slightly oval and slender, and the central line (Center Cut) is S-shaped and green, while the latter is round and fat, the central line is almost straight, and the color is whiter. For a detailed comparison, please refer to the table below, where Robusta contains almost twice as much caffeine as Arabica.

Differences in coffee taste

Arabica has a strong and round wet aroma. Coffee made from Arabica coffee has strong complex flavors such as flowers, fruit, chocolate caramel and so on. Arabica beans are rich in aroma and taste, and taste softer and palatable. Therefore, it occupies a major position in the market. The caffeine content is about 1.5%.

With a faint wet aroma (aroma) and a woody flavor (woody), Robusta produces coffee with a strong, distinct bitterness and low acidity. Robota beans have a single taste, bitter, and do not taste good enough. They are generally used in instant coffee, canned coffee, liquid coffee and other industrial production coffee, and a small part of them are used to prepare Italian concentrated mixed beans. It can improve the mellowness of espresso.

Planting condition difference

Arabica coffee has harsh planting conditions, weak disease resistance, high altitude requirements, slow growth, high quality, and fine processing of raw beans. Different producing areas have their own different flavor and aroma, rich taste and different taste! It makes it the only coffee among these original species that can be drunk directly and alone, and can be used as a single product or as an Italian blend of coffee.

Robusta coffee has the advantages of strong adaptability, easy planting, fast growth and high yield. in general, the treatment of raw beans is relatively extensive and low quality (there is also a small amount of washed refined robusta). The flavor is bright and strong, mainly bitter, with a bad rubber or mildew smell because of its low-level raw bean treatment. Most of the robusta beans are not suitable for drinking as a single product coffee. A few robusta beans are used as Italian blending ingredients, the proportion is very low (but do not rule out the possibility that very few high-quality robusta beans can reach more than half). In general, robusta coffee is used in instant coffee (which extracts about twice as much liquid as Arabica), canned coffee, liquid coffee and other industrial coffees.

Different flavors and characteristics

Arabica smells like grass when it is not baked, and after proper baking, it shows "fruity" (light baking) and "caramel sweetness" (deep baking). Generally speaking, it has a better aroma and flavor than Robota beans.

Robusta smells like raw peanuts when unbaked, and cheap robusta coffee beans usually taste between "wheat tea" (medium roasting) and "rubber tires" (deep roasting). It is difficult to show a fine flavor.

Difference between market price and use

High-quality Arabica coffee requires complicated manual picking, selection and meticulous processing, so the most expensive and best coffee beans in the world are Arabica coffee. "Robusta" coffee is usually used to produce instant coffee and canned coffee because of its low cost. A small number of better quality "Robusta" coffees are also used in blending (mixed with Arabica coffee) espresso beans.
