On the difference between Arabica Coffee and Robusta Coffee the difference between good beans and bad beans
The global coffee bean tree species are mainly divided into Arabica and Robusta, of which Arabica coffee beans account for about 65% and 80%.
Arabica coffee has harsh planting conditions, weak disease resistance, high altitude requirements, slow growth, high quality, and fine processing of raw beans. Arabica coffee beans are elegant and slender in shape, with large and uniform grains. 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). Robusta coffee has a round and rugged shape, relatively small grains, mixed beans, bright and strong flavor, mainly bitter taste, and has a bad rubber taste or mildew smell because of its low level of raw bean treatment. most Robusta beans are not suitable for drinking as a single coffee, and a few Robusta beans are used as Italian ingredients. The proportion is very low (but it does not rule out the fact that very few high-quality Robbosa beans can reach more than half of them). 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%.
The author believes that Arabica coffee and Robusta coffee can not be directly compared, after all, they belong to different tree species, each has different opportunities to show their talents! Just like beef cattle and cows, which side of the milk quality can be compared? Which side of the beef is of good quality?
Even all-Arabica coffee beans are not necessarily good coffee beans, even if more than half of the robusta coffee beans (refined beans) may be good coffee! Blending itself is to carry forward the espresso, but it is contemptible to mix it in a single cup of coffee.
