Complete steps of roasting coffee beans

Roasting is the process of heating raw coffee beans to develop their aroma and flavor. This process requires a series of steps, including selection, cleaning, drying, sorting and storage. Each step will be described in detail below.

1. Selection

Before you start roasting, you first need to select high-quality coffee beans. Good coffee beans should have a somewhat uniform and smooth appearance, without obvious defects or discoloration. In addition, you can also judge whether they are fresh by smelling them. High-quality coffee beans usually exude a rich and pleasant aroma.

2. Cleaning

The purpose of cleaning is to remove any impurities and contaminants that may exist on the surface. This step is very important because any impurities will affect the taste and quality of the final coffee. You can rinse it with water or soak it in water for cleaning.

3. Drying

After washing, the coffee beans need to be dried. The purpose of drying is to remove excess moisture from the coffee beans so that they can be roasted better. Generally speaking, the coffee beans can be placed in a well-ventilated and temperature-appropriate environment to dry naturally.

4. Classification

Classification is the process of dividing coffee beans into different grades or types based on factors such as variety, origin, and quality. This step can help us better understand the characteristics of each batch of coffee beans and make corresponding adjustments for the subsequent roasting process.

5. Baking

Now comes the most critical step - roasting. In this process, we need to control the time and temperature to make the coffee beans reach the ideal state. Generally speaking, lighter colors (such as light blends) will appear brighter, more acidic and refreshing, while darker colors (such as dark blends) will appear rich, bitter but with a strong aroma.

6. Cooling

After roasting, the coffee beans need to be cooled. This process is to prevent further roasting and preserve the flavor of the coffee beans. You can place the hot beans in a well-ventilated environment or use special cooling equipment.

7. Storage

The last step is to store the roasted coffee beans. In order to maintain their freshness and taste, they should be stored in sealed containers that are light-proof, moisture-proof, and low-temperature. At the same time, be careful to avoid contact with other foods or odors.

The above are the complete steps of roasting coffee beans. Through the steps of selecting, washing, drying, sorting, roasting, cooling and storing, we can make delicious coffee with rich taste and strong aroma.
