Coffee knowledge and skills: fully master the varieties, roasting, brewing and preparation methods of coffee

Coffee Varieties

Coffee is a beverage made from coffee beans, which come in many different varieties. The most common varieties include Arabica and Robusta. Arabica beans are generally considered high quality, with lower acidity and bitterness, while having a rich and complex taste. Robusta beans are more intense and bitter, suitable for full-bodied and darker roasted coffees.

Coffee roasting

Roasting is heating green beans to a specific temperature to change their color, aroma and flavor characteristics. Different types of coffee can be obtained according to different degrees of roasting. Light roasting usually retains the original flavor of the origin and has a bright and fresh taste; medium to medium-dark roasting adds some sweetness and chocolate-like taste; dark roasting makes the flavor more intense, bitter and has a distinct charred aroma.

How to brew coffee

Brewing is the process of bringing ground coffee powder into contact with water to extract the coffee. Common brewing methods include drip, French Press, and espresso. Drip is the most common and simple method, which involves slowly pouring water over the coffee powder and letting it flow into the container through filter paper; the French Press requires mixing the ground coffee powder with water and pressing it with a piston; and espresso is a type of coffee that is quickly extracted under high pressure and has rich oils and a strong flavor.

Coffee Preparation Method

In addition to the basic brewing method, there are many other ways to prepare coffee with different tastes and flavors. For example, adding milk or milk foam can make different types of drinks such as latte and upgraded half latte; adding chocolate or caramel can increase sweetness and complexity; adding spices such as vanilla or cinnamon can also add special flavors to coffee.
