Coffee bean roasting process analysis: from bean selection to tasting, step by step to teach you how to become a coffee roasting master

Bean Selection

The first step in coffee roasting is to select beans. Selecting high-quality coffee beans is the key to ensuring delicious coffee in the end. First, choose coffee beans that are fresh. You can check the production date on the package to determine. Second, choose coffee beans from different origins and processing methods according to your personal taste preferences.

Grinding

Before you start roasting, you need to grind the coffee beans to a moderate coarseness or fineness. A coarse grind is suitable for brewing methods such as French press or drip coffee, while a fine grind is suitable for methods such as espresso machines that require a longer extraction time.

Pre-processing

Before formal roasting, coffee beans can be pre-processed to improve taste and flavor. Common pre-processing methods include peeling, pulping, fermentation, etc. These steps will make coffee beans easier to absorb water and can enhance their complexity and sweetness.

Recipe Design

Recipe design is the roaster's determination of the parameters in the roasting process based on his own experience and taste preferences. This includes roasting time, temperature, wind speed, etc. Different recipes will produce coffee with different flavor characteristics, so they need to be adjusted according to personal preferences.

Heat Treatment

Before the formal roasting begins, the coffee beans need to be subjected to a short and high temperature treatment to remove moisture from the surface of the beans and make them expand. This process is called "burst" and usually lasts for several minutes.

Main baking stages

The main roasting stages include preliminary distillation, yellowing, first crack, second crack and cooling. At each stage, the temperature and time need to be controlled to ensure that the coffee beans are evenly heated and achieve the desired flavor.

Taste and adjust

After the entire roasting process is completed, you can taste the beans to evaluate the quality of the final product. Tasting can tell whether the coffee beans have achieved the expected flavor and can make adjustments as needed. If you find that the taste is not strong enough or the acidity is too high, you can try to increase the roasting time or lower the temperature to improve it.

Preservation and storage

Finally, be sure to store the roasted coffee beans in a dry, cool place, away from sunlight and air. Using a sealed container to store the coffee beans in a refrigerator or other appropriate place can extend its shelf life and maintain its flavor.

Summarize

Through the above steps, we can understand the complete coffee roasting process from bean selection to tasting. Each step needs to be carefully controlled and adjusted to ensure that the final quality meets expectations. I hope this article can help you become an excellent coffee roasting master!
