espresso: 35 grams of essence extracted from 20 grams of coffee, of which the importance of coffee powder can be imagined.

When buying coffee, it is better to buy coffee beans rather than ground coffee. Although they are essentially the same, the reality is that ground coffee is very easy to oxidize and is not easy to preserve. Even if those coffee powders that seem to be able to be preserved for a long time are actually added with a lot of preservatives, which will greatly affect the taste of the coffee that will be brewed later. Therefore, if you want to make a good cup of coffee, the best and most correct way is to grind the coffee on the spot before brewing the coffee, so as to maintain the aroma and taste of the coffee to the greatest extent. Generally, coffee beans can be preserved for about a month. But if it's coffee powder, it shouldn't last more than five days.

There are two types of coffee beans: Arabica and Robusta. Generally speaking, Arabica is mainly used for single or fine coffee, and Robusta is used to make instant coffee. Although Arabica can be defined as premium coffee and Robusta as secondary, it does not have to be classified as such, and it is more appropriate to distinguish it according to your preferred taste. In terms of taste orientation, the United States and Japan drink Arabica brewed weak coffee more often, while Europe prefers Arabica mixed with Robusta espresso. So if you have the right conditions, you'd better choose Arabica Italian beans.
