Qianjie-Introduction to Coffee Bean Varieties

Arabica, synonymous with premium coffee

Arabica accounts for about 70% of the world's coffee production, and most of the coffee beans we call "raw beans" in daily life are Arabica varieties. Arabica coffee is considered synonymous with premium coffee beans because of its attractive aroma and rich flavor. This coffee characteristic is closely related to its cultivation environment.

Ethiopia's plateau is the origin of Arabica species, probably Arabica species in the equatorial plateau, it is neither heat nor cold, only in the annual average temperature maintained at 15-25℃ can be cultivated.

The equatorial circle is the only place where the temperature is stable and there are no seasons like this. But the average temperature in this area is quite high, making it difficult to grow directly on the ground. Therefore, coffee is cultivated on the plateau by using the principle that the temperature drops by 1℃ for every 100m rise in altitude. For example, in the equatorial region with an annual average temperature of 40 ° C, the temperature can be maintained at about 25 ° C in the plateau area with an altitude of 1500m. Only in this place can coffee grow.

In addition, the average temperature in the plateau is maintained at about 25 ° C, but the temperature difference between day and night is very large, which has a close impact on plant photosynthesis and respiration.

During the day, the temperature is high, the sunshine is strong, the photosynthesis is very active, and a large amount of glucose and other good components can be formed. On the contrary, the temperature drops sharply at night, which relatively reduces the respiration. Such cultivation conditions highlight the characteristics of Arabica species, making the fragrance more rich and complex, and producing high-quality sour taste. Just like vegetables at high altitudes and in cold weather, they taste crisper and sweeter than ordinary vegetables.

Arabica seed beans are flat, with a curved center line and almost no gaps. From the side to see the winding curve, touch slightly moist soft feeling.

Robusta, not just for instant coffee

Robusta species, first found in Congo. More tolerant of heat and humidity than arabica, it can be grown at lower elevations, where respiration is more active than photosynthesis. The sugar and other components produced by photosynthesis in this flatland plant are partly consumed in the production of coffee aroma and taste, and most of them are consumed in the formation of plant root and branch tissue. Such cultivation conditions give Robusta beans their inherent characteristics.

Compared with Arabica species, Robusta species has a lighter aroma and a bitter taste than sour taste. Extract this freshly roasted Robusta coffee beans, exudes a corn tea like aroma, alcohol, thickness are very strong.

Robusta is generally used to make canned coffee and drink instant coffee. The main reason is the relatively low price compared to Arabica. In addition, there is a strong correlation with Robusta's bitter taste and good texture. Robusta coffee itself has a very good texture, and some aroma may be lost during processing, but some coffee that can enhance aroma can be added to make up for it, which can also reflect the freshness of coffee. It is also used in espresso coffee blends. Robusta seeds can extract rich coffee and high quality oils even when lightly roasted.

It is difficult for consumers to buy good Robusta coffee beans because most Robusta beans are mass-produced as instant coffee, and most Robusta beans in circulation are poor quality and low price raw beans. Because of this, Robusta beans are often misunderstood as inferior coffee beans.

Robusta beans are fuller than arabica beans, split vertically along the center line, usually flat or raised in the middle when viewed from the side, harder to the touch than arabica beans, and feel like pebbles.

Knowledge point: Robusta coffee beans not only act as a "price changer," but also enhance the body of coffee.

In brief: Qianjie is a coffee research center, happy to share knowledge about coffee with everyone, we share it without reservation only to let more friends fall in love with coffee, and there will be 3 low discount coffee activities every month, because Qianjie wants to let more friends drink the best coffee at the lowest price, which is also the purpose of Qianjie for 6 years!
