Variety classification of high-quality coffee beans and knowledge coffee

The varieties of coffee beans (Coffee Bean) can be divided into three types, namely

Arabica-Coffee contains about 1% per cent of caffeine by weight. Generally speaking, better quality and more expensive coffee beans come from coffee beans grown by Elaraby. It accounts for 3/4 of the world's output and is of good quality. because the coffee tree itself is very sensitive to heat and humidity, the growth conditions are at least 900m higher than the highland climate at sea level. the higher the height, the better the quality of the coffee beans. The caffeine content of this variety is low (1.1 ~ 1.7%). The color of coffee beans is green to light green, oval in shape and curved in grooves.

Robusta (Robusta)-Coffee contains about 2% of caffeine by weight. It accounts for about 20% and 30% of the world's output. It has strong resistance to tropical climate and is easy to cultivate. It grows very well at a sea level of 200 ─ 300m. However, its unique resistance also makes its concentration higher and its taste more bitter. Its caffeine content is high (20.4%). Coffee beans are round in shape, brown in color and with straight grooves.

Liberica-except for a few producing countries, only Europeans drink it. The aroma is poor, the bitter taste is strong, and the top of the coffee bean is diamond-shaped.

The variety of coffee

Variety Arabica (plateau cultivation) Robusta (lowland cultivation) Liberica (minimum cultivation)

Production accounts for about 70% of the world's total output, about 80% of the world's total output, about 20% of the world's total output and 30% of the world's total output, except for the consumption of the few countries themselves, only people on the continent can use it.

Cultivated land "high 500m~1000m" slope below 500m high slope below 200m lowland or flat land

The parts should be high, low, high and low.

The amount of rain should be more rain, less rain, more rain, less rain, less rain.

The height is 5m ~ 7m5m10m

In fact, the exocarp is hard, the endocarp is also solid, and it is easy to fall when it is ripe. The pericarp is very thin between the exocarp and the endocarp, and more than a dozen conditions can be seen on the surface of the pericarp. After ripening, the pericarp is not easy to fall, and the pericarp is thin, so it is easy to separate from the seed. As a matter of fact, the pericarp, endocarp and pericarp of Arabica are all very thick, especially the peel is glued to the peel, and the hard work of removing the peel is not easy to fall after maturity.

The length of the 15cm is about the shape of the cymbals, and the surface of the slices is dark and glossy. The length of 10cm~20cm is slightly lower than that of Arabica, the meat is thinner than Liberica, the surface of noodles is bulging, and the whole noodles can be seen undulating like waves.

The taste is good, the smell is good, there is a lack of aroma, the bitter taste is strong, the sour taste is not good, the bitter taste is strong.

It is characterized by poor disease tolerance and shelter in places with low degrees from 15 to 20 degrees. The adaptability is strong, and the harvest quantity is the highest among the three original species. Because of its strong disease tolerance and adaptability, it is often used as the original rootstock of Arabica.

The highest density of the species is about 1.5 times of Robusta and 2 times of Liberica. The lowest in the middle of the river
