The origin of coffee

Coffee is a drink made from ground coffee beans that originated in Africa. According to legend, in the 9th century AD, a shepherd named Kaldi found that his sheep became unusually active after eating a kind of red fruit. So he tried to boil these fruits and drink them, and found that he also became energetic. This is the earliest story of coffee known to people.

Coffee Culture

Over time, people began to enjoy coffee as a social and cultural activity. From Europe to Asia, different regions have formed their own unique coffee culture. For example, in Italy, strong and concentrated espresso is popular, while in Turkey, there is the Turkish sand pot brewing method.

Different types of coffee beans

There are two common types of coffee beans on the market: Arabica and Robusta. Arabica beans have a softer taste and higher acidity, suitable for making delicate coffee, while Robusta beans are more intense and bitter, suitable for making espresso.

Baking process

Roasting is the process of subjecting raw beans to high temperatures to produce aroma and flavor. Different degrees of roasting will bring different tastes and flavors of coffee. For example, light roasting will retain the original acidity and floral and fruity aroma of the beans; medium roasting will add some chocolate or nutty flavors; and deep roasting will produce bitterness and cocoa flavors.

Brewing method

Brewing is the process of bringing coffee powder into contact with water and extracting the dissolved substances. Common brewing methods include drip, French press, espresso, etc. Each method has its own characteristics, and you can choose the brewing method that suits your taste needs according to your personal preferences.

Mixing Tips

In addition to basic brewing techniques, blending is also an important skill. By adjusting factors such as the amount of coffee powder, water temperature and brewing time, you can affect the taste and flavor of the coffee. For example, finer ground coffee powder is suitable for espresso, while coarser ground coffee is suitable for drip coffee.
