Coffee bean roasting: tasting the aroma, with a unique process at the heart

The roasting process of coffee beans is one of the key steps in making delicious coffee in a coffee shop. Different roasting degrees and procedures can give coffee beans different flavors and tastes. This article will focus on tasting the mellow aroma and unique procedures, and introduce the process and techniques of coffee bean roasting.

1. Raw material selection

Before roasting coffee beans, you first need to select high-quality raw materials. High-quality coffee beans usually have a higher water content, uniform size, and complete shape. In addition, you can also choose coffee beans from different origins and types according to your personal preferences.

2. Green processing

Before the actual roasting, the selected raw materials need to go through some processing steps. The first is to remove impurities and residues and ensure that each coffee bean is in a similar state.

The next step is to treat the beans without any processing or fermentation, which is called "green embryo". This step is to preserve the original flavor and characteristics of the coffee beans.

3. Baking process

Roasting is heating the raw embryo to a certain temperature to cause chemical changes inside it, thus producing the unique aroma and flavor of coffee beans. Here are some common roasting degrees:

- Light roasting: lower temperature and shorter time. At this level, the coffee beans retain more acidity and floral and fruity aroma.

- Medium roast: moderate temperature and time. At this level, the coffee beans have a balanced sweet and sour taste and rich chocolate or nutty aroma.

- Dark roasting: The temperature is higher and the time is longer. At this level, the coffee beans will have a distinct bitter taste and emit rich aromas such as cocoa, wood or charcoal.

4. Cooling and storage

After roasting, the coffee beans need to be cooled to stop their further changes. Usually a cooler or natural fan is used for cooling. The cooled coffee beans need to be placed in a ventilated and dry place, away from direct sunlight and humid environment.

In order to maintain the freshness and quality of coffee beans, it is recommended to store them in a sealed container and avoid exposure to air. In addition, it is best to mark the roasting date on the package for timely consumption.

5. Unique Program

In addition to the above conventional steps, some unique procedures can also give coffee beans a richer and more diverse flavor. For example:

- Aging: coffee beans that have been roasted and stored for a period of time are stored for months or years to allow microbial changes to occur under appropriate conditions. This method can increase the aroma and complexity of the coffee beans.

- Blending: Mixing coffee beans from different origins, types or degrees of roasting together for roasting. This can create a more layered and complex taste.

Through careful selection of raw materials, scientific processing and unique procedures, the roasting process of coffee beans can bring delicious coffee to our coffee shop copywriters. Whether it is light roasted, medium roasted or dark roasted, each degree has its own unique flavor and taste.
