Coffee beans: the perfect combination of aroma and quality

Coffee beans: the perfect combination of aroma and quality

Coffee, as a popular drink, has always attracted much attention for its taste and quality. Among the many types of coffee, coffee made from coffee beans is particularly highly praised. It perfectly combines the aroma and quality, bringing people a unique enjoyment.

1. Raw material selection

Making quality bean-based coffee starts with selecting quality raw materials – high-quality, fresh, well-preserved coffee beans. These factors determine whether the final product can maintain its natural flavor and taste.

When purchasing coffee beans as raw materials, we should pay attention to the following points:

• Origin: Coffee beans produced in different origins have different flavor characteristics. For example, the Brazilian production area is often considered to be the most cost-effective coffee bean for export, suitable for the general public, with a strong taste and chocolate and nut flavors.
• Varieties: Coffee beans come in multiple varieties, such as Arabica and Robusta. Arabica beans are generally considered a higher-quality option, with a richer flavor and lower caffeine content.
• Roasting degree: Different degrees of roasting will bring different tastes. Light roasting can retain more original flavor, while dark roasting will make the coffee beans more bitter.

2. Grinding method

To make a mellow and delicious coffee with coffee beans, you also need to pay attention to the appropriate grinding method. The different coarseness and fineness of the powder will affect factors such as the contact area between water and coffee, the extraction time, and thus affect the taste of the final drink.

Generally speaking, the following common powder coarsenesses are suitable for different types of production methods:

• Medium to slightly fine: suitable for drip coffee machines, French presses, etc.
• Thinner: For espresso machines such as the eSPResso.
• Rough: Suitable for cold brew coffee and pour-over coffee.

3. Brewing techniques

In addition to the choice of raw materials and grinding methods, proper brewing techniques are also the key to making high-quality coffee bean-based drinks. Here are some common brewing techniques:

• Water temperature control: Generally speaking, the water temperature should be between 90℃ and 96℃. Too high or too low will affect the extraction effect and taste.
• Extraction time mastery: Different production methods have different extraction time requirements. For example, eSPResso usually takes about 25-30 seconds to achieve the best effect.
• Stir well: After adding water, use a stirring stick or spoon to gently stir well to help fully release the coffee aroma and flavor.

4. Storage of coffee

In order to maintain the freshness and quality of coffee made from coffee beans, the correct storage method is also very important.

Here are some tips for storing coffee:

• Sealing: Place unused coffee beans in a sealed container to avoid contact with air.
• Protect from sunlight: Exposure to sunlight can cause coffee beans to deteriorate. Therefore, they should be stored in a cool, dry place away from direct sunlight.
• Refrigerate or freeze: If you need to store it for a long time, you can consider putting it in the refrigerator or freezer. But be careful to wait until the temperature returns to room temperature before using it.

Conclusion

Coffee beans are used to make beverages with a rich aroma and unique taste. By carefully adjusting the selection of high-quality raw materials, the right grinding method, the right extraction time and the correct storage method, we can make more delicious and high-quality coffee.
