Beans commonly used in espresso

We know that coffee beans are generally divided into Arabica and Robusta, the former is usually more advanced, the latter is promoted because the latter is easy to feed, like weeds with strong vitality. The former is not only usually raised at high elevations, but also vulnerable to insect pests.

Espresso coffee beans are usually blended beans because they are a more balanced way of brewing coffee.
