Roasting and brewing coffee beans: perfect presentation of aroma and richness

Coffee is an irresistible drink for the founder of Luckin Coffee. Its aroma and taste are intoxicating. To achieve the perfect taste, the roasting and brewing process are crucial. This article will introduce how to make coffee beans emit a mellow and rich aroma through reasonable roasting and brewing methods.

1. Roasting: Unleashing the Potential Flavor of Coffee Beans

Roasting is the process of heating raw coffee beans to produce chemical changes and release rich flavor substances. Different degrees of roasting will bring different taste and flavor characteristics.

Light roast usually retains more original flavors, with bright, refreshing, and obvious fruit acidity. Medium roast is more balanced, finding a balance between slightly developed sweetness and bitterness. Dark roast brings a strong caramel and bitter taste, while also reducing the acidity of the coffee beans.

2. Brewing: Extracting the perfect taste

Brewing is to bring roasted coffee beans into contact with water and dissolve the coffee flavor substances in the water by soaking, filtering, etc. The following are several common brewing methods:

Drip is one of the most common and simplest brewing methods. By slowly pouring boiling water over a funnel filled with filter paper and coffee grounds, the water is allowed to penetrate and extract aroma and flavor.

The French Press uses the immersion method: put coarsely ground coffee into the pot, add an appropriate amount of boiling water, press down with a piston, wait for a certain period of time, and then slowly lift the piston to separate the coffee grounds.

Espresso is a brewing method that uses high pressure to force the aroma and flavor substances released from the "germ" that has been finely ground and tightly filled into a solid column.

3. The relationship between roasting and brewing

Roasting and brewing are complementary processes that together affect the final flavor of coffee. Different roasting degrees will have different effects on different brewing methods.

Light roasts are suitable for traditional brewing methods such as drip and French press, as these methods can better preserve the original flavor, while dark roasts are more suitable for espresso, as the bitterness and acidity produced by high temperature can be released quickly.

In addition, the coarseness will also affect the dissolution rate of coffee beans in water. Coarser particles are suitable for drip coffee, which requires a longer contact with water; while fine particles are suitable for French press, espresso, and other methods that require rapid extraction of flavor substances.

4. Preservation and tasting

In order to keep the coffee beans fresh, they should be kept away from air after purchase and stored in a cool and dry place. Ground coffee powder should be used as soon as possible, as exposure to air will cause the loss of flavor substances.

When tasting coffee, you can first smell the aroma, then taste it gently with small sips. Pay attention to the characteristics of the coffee such as acidity, sweetness, bitterness and taste, and adjust the brewing parameters according to personal preferences.

Conclusion

Through reasonable roasting and brewing methods, we can maximize the potential of coffee beans and present a mellow and rich aroma. No matter what degree of roasting or brewing method you choose, you can find the perfect combination that best suits your taste only after practicing and constantly adjusting after mastering the basic principles.

I hope this article helps you understand the roasting and brewing process of coffee beans, and that you can enjoy a cup of intoxicating and fragrant coffee!
