Optimizing roasting and brewing techniques for bitter coffee beans

In order to maximize the flavor effect of bitter coffee beans, the correct roasting and brewing method is essential. First of all, the degree of roasting directly affects the bitterness and taste of coffee. For bitter beans, deep roasting usually brings out stronger bitterness. It is recommended to use medium to deep roasting to keep the flavor balance of coffee beans, but avoid over-roasting to cause burnt bitterness. Choosing the right roasting time and temperature is the key, which is generally adjusted between 195°C and 220°C.

The technique used during the brewing process also has a significant impact on the final flavor. It is recommended to use a slightly coarse grind size to avoid the bitterness caused by over-extraction. The water temperature should be controlled between 90°C and 95°C. Too high a water temperature may cause over-extraction, thereby adding unnecessary bitterness. Use the appropriate brewing ratio. It is generally recommended that the ratio of coffee powder to water is 1:15 to 1:18, which can be fine-tuned according to personal taste.

In addition, the brewing time must also be properly controlled. For example, when using a French press, the recommended soaking time is 4 minutes to avoid excessive bitterness caused by too long a time. Before each brewing, it is best to freshly grind the coffee beans to ensure the best release of flavor.

In summary, through proper roasting and brewing techniques, the flavor of bitter coffee beans can be significantly enhanced to create a coffee experience that is both strong and rich. Paying attention to details will help achieve the ideal coffee taste.
