Coffee bean production guide: from purchasing to roasting, step by step to teach you how to create a perfect coffee experience

Buy coffee beans

Choosing coffee beans is the first step to making the perfect cup of coffee. When choosing coffee beans, we need to consider the following factors:

1. Coffee Origin: Coffee from different regions produces different flavor characteristics. For example, coffee from Brazil often has rich chocolate and nutty flavors, while coffee from Ethiopia has floral and fruity notes.

2. Coffee types: The two main types are Arabica and Robusta. Arabica beans are generally considered to be of higher quality and have a smoother and more delicate taste, while Robusta has a higher bitterness and richness.

3. Roasting degree: The roasting degree also has a great impact on the taste. Light roasting will retain more original flavors, but may bring sourness; medium roasting is moderately balanced; dark roasting will make the beans shiny and give them a spicy or bitter taste.

When buying coffee beans, try a combination of different origins, types, and roasting levels to find the flavor you like.

Roasted coffee beans

Roasting is the process of heating green coffee beans to a certain temperature, causing the water inside to evaporate and chemical changes to occur. Here are a few key steps to consider in making the perfect cup of coffee:

1. Baking equipment: Choose a small baking machine suitable for home use or a manual operation method. Make sure the equipment can control temperature and time.

2. Storing green beans: Before you start roasting, store freshly purchased green beans in a dry, light-proof, and well-sealed container. Avoid exposure to air to prevent oxidation.

3. Green to yellow: After starting to heat, observe the color change of the coffee beans. From the initial state (dark brown) to yellow means that the water evaporation process is going well.

4. First pop: When you hear the first pop, it means the carbon dioxide inside the coffee beans begins to release. At this point, the color of the coffee beans turns light brown.

5. Control the degree of roasting: According to personal taste preferences and the characteristics of the selected coffee beans, control the degree of roasting. Light roasting produces sourness and floral aroma; medium roasting brings a balanced taste; deep roasting increases bitterness and richness.

6. Cooling and storage: Cool the roasted coffee beans quickly and store them in a clean, sealed container. Wait 24-48 hours for the carbon dioxide to be fully released and the flavor to be more balanced.

Brewing the perfect coffee

After purchasing good coffee beans and roasting them properly, the next step is to learn how to brew the perfect cup of coffee:

1. Grind to the right coarseness: Grind to the right coarseness based on the brewing equipment you are using. A coarser grind is better for a French press or hand brewing equipment, while a finer grind is better for immersion brewing.

2. Ratio control: Usually, 15 grams of coffee powder is needed for every 250 ml of water. Adjust the ratio according to personal taste.

3. Control the water temperature: The temperature of the hot water should be between 90-96 degrees Celsius. Too low will result in insufficient extraction, while too high may produce a bitter taste.

4. Brewing time: Different brewing methods have different time requirements. For example, a French press takes about 4 minutes, while a hand brewing device can adjust the time according to personal preference.

5. Evenly soak: Make sure all the coffee grounds are evenly soaked, and wait for the expansion and carbon dioxide release process to complete before proceeding to the next step.

6. Pour slowly: Use a slow, even pouring motion when filling to ensure even extraction and avoid funneling or clogging.

Enjoy the perfect coffee

After a series of steps including shopping, roasting and brewing, you can now enjoy the perfect coffee you made yourself:

1. Taste: Pour the brewed coffee into a cup and savor its aroma and taste. Pay attention to the color, smell, and taste.

2. Adjustment: If you find that the taste does not meet your expectations, you can try to adjust factors such as the degree of grinding, water temperature or brewing time to achieve a more satisfactory result.

3. Share with others: Share the coffee you have prepared with your family and friends, so that everyone can experience the joy of the perfect coffee you have made yourself.

Conclusion

From purchasing to roasting to brewing, each step has an important impact on the final coffee experience. By understanding the relationship between different factors and adjusting them according to personal preferences, we can create coffee with our own perfect taste and flavor characteristics. I hope this article can provide you with useful guidance and enjoy the unlimited fun of coffee after a new level of improvement!
