Coffee knowledge and skills revealed

Coffee is a popular drink that is indispensable for both morning refreshment and afternoon tea. However, do you know the knowledge and skills behind coffee? This article will reveal the secrets of coffee for you.

1. Classification of coffee beans

First, let's take a look at the classification of coffee beans. Depending on their origin and processing methods, coffee beans can be divided into two categories: Arabica and Robusta.

Arabica beans are higher quality and lower yielding, grow at higher altitudes, and require more attention and care. They typically have a floral and fruity aroma, a smooth taste, and moderate acidity.

Robusta beans grow at lower altitudes and are more adaptable to the environment. They usually have a strong bitter taste, higher caffeine content and are relatively cheap.

2. Coffee roasting degree

The degree of roasting of coffee beans has an important influence on the taste and flavor. Generally speaking, coffee beans can be divided into three different roasting degrees: light roasting, medium roasting and dark roasting.

Light roasting usually retains the original acidity and fruity aroma of coffee beans, and has a lighter taste. Medium roasting retains a certain acidity and rich flavor while adding some cocoa or nut-like flavors. Dark roasting emphasizes the bitter taste and has a lower acidity.

3. Coffee Brewing Techniques

Correct brewing techniques can improve the quality of coffee. Here are some common brewing methods:

- Drip method: Place the ground coffee into filter paper and extract with the help of a filter.

- French Press: Stir the coarse coffee powder and water thoroughly, let it sit in the container for a while, and then use a filter to isolate the solid particles.

- Espresso: Uses high-pressure steam to pass through fine coffee powder to produce a rich Italian coffee.

4. Coffee Latte Art

If you like to enjoy a professional-level coffee experience at home, then learning some latte art techniques is essential. Here are some common latte art techniques:

- Heart shape: Pour the milk foam into the cup at an angle and draw a heart shape on the surface.

- Love Heart: Similar to the heart shape, but requires more delicate and skilled techniques to complete.

- Flowers: Create a variety of beautiful floral patterns in the cup by controlling the flow speed and posture of the milk foam.

5. Storage and preservation

To keep the coffee beans fresh, it is important to store and preserve them correctly. Here are some suggestions:

- Try to buy whole beans and grind them yourself to take advantage of the freshness.

- Store unused coffee beans in an airtight container away from air.

- Avoid placing coffee beans in the refrigerator, as humidity and odors inside the refrigerator may affect the flavor of the coffee.
