Comparison between Arabica coffee and Robusta coffee

When comparing  Arabica and Robusta which is better, people will feel and judge based on the taste of each. Arabica coffee has a mild bitter taste, pure gentle aroma due to the caffeine content of Arabica beans only from 1-2%. Robusta has a bitter, slightly acidic taste and a stronger aroma than Arabica because the caffeine content in Robusta beans accounts for 2-4%.

That is why many people prefer the taste of Arabica over Robusta because of its mild and moderate purity. However, in some countries, they prefer the sour and bitter taste of Robusta coffee. Today, to create the perfect flavor for coffee, people often mix both types of coffee together in certain proportions. For example, Italian Espresso coffee often uses the ratio of Arabica: Robusta according to the formula 9 : 1 to get a little sour taste of Robusta blended to enhance the taste of pure Arabica.

Arabica coffee has a caffeine content of only 1-2%, so it has a mild bitter taste, a gentle aroma and a sweet and sour taste. As for Robusta beans, due to the higher caffeine content than Arabica, accounting for 2-4%, the taste is somewhat darker.

Therefore, according to experts and "coffee connoisseurs", Arabica beans will give a more delicious, diverse and delicate flavor than Robusta. However, for Vietnam - the capital of Robusta, the taste of Arabica beans is still quite new. People are more "infatuated" with Robusta's rich bitter taste, especially when mixed with condensed milk. That's why the culture of "coffee with iced milk" is favored by Vietnamese people.
