Comparison of parameters between Arabica and Robusta Coffee

Coffee beans are the seeds of Rubiaceae Family plants. There are at least 25 main varieties of Coffea Genus, among which the two most important varieties are Arabica species Coffea arabica (Arabica coffee) and Canafora species Coffea canephora (Robusta coffee), also known as Robasta Coffee. Arabica coffee beans account for 70% of the world's production, Robasta coffee beans account for about 30%, Arabica coffee has 44 chromosomes, while Robasta coffee has 22 chromosomes. therefore, Arabica coffee is a crop that cannot be crossed with Robasta coffee.

Coffee trees will be affected by regional climate, altitude, soil and other factors, affect the quality and flavor of coffee beans, like other agricultural products, such as tea and wine and so on. So even if you come from the same country, different regions have different flavors, and the price is naturally different. Coffee trees are evergreen plants and are cultivated in tropical and subtropical areas. the most suitable growth conditions are that there should be an appropriate amount of Rain Water, and the drainage of the land is good, so they are mostly selected on sloping slopes rich in volcanic ash (rich in organic matter). Therefore, most of the high-quality Arabica coffee beans are harvested manually and carried down the mountain by horses or mules.

The bean shape of Arabica coffee is small, the front is long oval, the middle split crack is narrow and tortuous, S-shaped, and the arc on the back of the bean is more complete. The bean shape of Robasta coffee bean is larger, the front tends to be round, and the split line crack in the middle is in a straight line.

As far as planting is concerned, Robasta coffee tree has the characteristics of high temperature resistance, cold resistance, drought resistance, moisture resistance, resistance to diseases and insect pests and strong adaptability, and can grow well on flat ground. unfortunately, the coffee beans produced are lack of aroma. Strong bitterness (because of too much caffeine), lack of acidity, so it is mostly used in instant coffee, canned coffee, or brewed three-in-one coffee. In Italy, many coffee shops add an appropriate proportion of Robusta Robasta beans to make espresso (Espresso) to enhance the "taste" (such as strong, rough, etc.).

Many people know that Arabica Coffee is famous, but they don't know the difference between Arabica Coffee and Robasta Coffee, which is commonly used in canned drinks.

In the end, there should always be a conclusion, perhaps it should be called the comparison of quality and quantity (quality vs. Quantity), Arabica coffee represents [quality], while robastian coffee represents [quantity].
