The Three Scales of a Coffee Bean Roaster: Mastering the Art of Roasting

Mastering the Art of Baking

Coffee bean roasters are one of the most important tools for baristas to use in roasting. By mastering the art of roasting, we can bring out the flavor and aroma of coffee beans to the fullest. When using a coffee bean roaster, there are three important scales to pay attention to.

Scale 1: Time

Time is one of the key factors affecting the degree of coffee bean roasting. Different degrees of roasting will give coffee different flavor characteristics. Generally speaking, light or medium-light roasting will retain more original flavors, while deep or extra-dark roasting will make the bitterness and cocoa flavors more prominent.

However, not all types of coffee are suitable for the same amount of time. Each type and variety has its own specific needs, and the time needs to be fine-tuned according to the actual situation. In addition, the ambient temperature and humidity will also affect the required time.

Scale 2: Temperature

Temperature is another crucial factor. At different temperatures, the chemical reactions in the coffee beans produce different results. Roasting at a lower temperature can retain more acidity and floral aromas, while higher temperatures will make the coffee beans sweeter and fuller.

However, too high or too low a temperature may lead to roasting failure. Therefore, when using a coffee bean roaster, it is necessary to adjust it according to the specific situation and maintain stable temperature control throughout the roasting process.

Scale 3: Air volume

Air volume refers to the force of air flow applied to coffee beans during the roasting process. Proper air volume can help exhaust waste gases and promote uniform heating, thereby achieving better control of the coalification reaction rate.

However, not all types and varieties require the same strength or frequency of wind. Some types and varieties may require stronger or continuous wind to achieve the desired effect, while others only require slight disturbances.

Summarize

By properly adjusting the three scales of time, temperature and air volume, we can better master the art of coffee bean roasting. Different scale combinations will bring different flavors and aromas, making each cup of coffee a unique and delicious experience.

When using a coffee bean roaster, we need to make fine adjustments according to the specific situation and maintain stable temperature control and wind speed. Only through continuous practice and experimentation can we truly master the art of roasting and bring more surprises and enjoyment to people.
