Arabica coffee beans grow at colder high elevations in the tropics, and those high temperatures and low elevations that are not suitable for Arabica are the land of Robusta.

Robstado grows in the lowlands at 200-600m above sea level and likes warm climates. the temperature is 24-29 ℃, and the requirement for rainfall is not high. However, the variety depends on insects or wind to pollinate, so it takes 11 months from pollination to fruit, which is longer than the Arabica species.

Feature editor

The coffee tree planted by Robusta is a kind of tree between shrubs and tall trees. Its leaves are long and bright green. The tree can be up to 10 meters high, but its roots are very shallow. The fruit is slightly rounder and smaller than Arabica coffee. The bean body is flat and round. The middle pit is straight.

Robusta has a unique aroma (known as "Rob smell", which some people think is moldy) and bitter taste. If 23% of the coffee is mixed with other coffee, the whole cup of coffee will become Rob flavor (therefore, Robusta coffee beans can not be drunk as individual coffee beans).

Its flavor is so bright and strong, but if you want to taste it directly, you have to be prepared.

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.

Its caffeine content is much higher than that of Arabica, about 3.2%.

Luodou is indeed relatively cheap, as for the flavor, this is more complex, beans are characterized by bitter taste and astringent feeling. In addition, mugi-cha is usually shown in the treatment of origin. If you walk back, there will be cream and so on. And then there's a disgusting smell of rubber leather. As for why Luodou is used, I dare not make a wild guess. But Luodou is a primitive bean species, with the different processing of the origin, the performance is also thousands of, I have not come into contact with the first-class, but can not deny that it does not exist.
