Coffee basic knowledge five rumors about coffee
Espresso coffee contains more caffeine than drip coffee.
Given the small portion size of Espresso coffee, it may contain more caffeine than drip coffee. But in fact, the two kinds of coffee are only relatively comparable, and the caffeine content of coffee depends on the variety of coffee, the degree and level of coffee roasting and the brewing technology. USDA data show that 2oz's espresso contains about 120mg caffeine, which is roughly equivalent to the caffeine content of 10oz dripping or soaking coffee.
But in fact, people think that Espresso coffee is refreshing, more because espresso has a strong taste, and there are few factors in caffeine content.
Arabica is king.
This statement is not scientific. Because Arabica and Robusta have different levels of application, there is no so-called contest between them. In recent years, the growth of boutique coffee market is the real reason for the increase in planting area and output of Arabica coffee. About 75% of the world's coffee producers choose Arabica simply because Arabica is more profitable.
However, the cultivation and yield of Robusta is more stable, because the main application of Robusta is in the production of instant coffee and espresso beans.

People avoid caffeine for many reasons, such as pregnancy, heart disease, allergies, insomnia, ideology and so on. But this does not hinder people's love of coffee, decaffeinated coffee drinkers are real coffee lovers, they simply enjoy the taste of coffee, not for the stimulation of caffeine.

Every cup of fancy coffee requires a lot of labor, from the cultivation of coffee beans, the production of raw beans, the roasting of coffee beans and the production of baristas, which are labor-intensive manual work, unlike enjoying a cup of instant coffee at home. Its price is cheap because of mechanical mass production.
