How to grind coffee beans into powder and brew them correctly

How to select and preserve high-quality coffee beans

When choosing coffee beans, you first need to understand the characteristics of different types of coffee beans. Arabica beans usually have a complex flavor and high acidity, which is suitable for people who like a delicate taste; while Robusta beans have a strong flavor and contain more caffeine, which is suitable for people who need a strong refreshing effect. It is crucial to choose the right beans according to your personal taste and needs.

When choosing high-quality coffee beans, you can start with the appearance and smell. High-quality coffee beans have a smooth and shiny surface, uniform color, and no obvious cracks or defects. In addition, fresh coffee beans should have a strong aroma. If the aroma is weak or has an odor, it may not be fresh enough.

In order to maintain the freshness of coffee beans, the storage method is also very important. Coffee beans should be stored in a sealed container in a cool and dry place, away from direct sunlight and moisture. If possible, it is best to store coffee beans in batches and use them up in a short period of time to ensure that each brewed coffee can maintain the best flavor.

Basic coffee brewing steps and equipment selection

The basic steps of brewing coffee first include preparing the water temperature. The ideal water temperature should be between 90 and 96 degrees Celsius. Water temperature that is too high may cause the coffee to be over-extracted and produce a bitter taste, while water temperature that is too low may make the coffee taste weak. Using a temperature-controlled kettle can help to accurately control the water temperature.

The ratio of coffee powder to water is also a key factor. Generally, a ratio of 1:15 is recommended, which means 1 gram of coffee powder for every 15 grams of water. The specific ratio can be adjusted according to personal taste, but keeping a stable ratio will help to achieve a consistent flavor.

Choosing the right brewing utensil has a significant impact on the flavor of your coffee. A drip pot is suitable for daily use, is easy to operate, and can produce refreshing coffee; a French press can produce a strong and rich coffee, but be careful not to over-stir when operating; an Italian coffee machine is suitable for making espresso, so make sure the coffee powder is ground finely enough and adjust the appropriate pressure.

Each brewing method has its own unique steps and precautions. When using a drip pot, make sure the filter paper or mesh is clean to avoid affecting the taste of the coffee. French press pots should press the piston steadily and evenly when brewing, while espresso machines need regular cleaning and maintenance to ensure the consistency of the coffee taste.

Key factors for optimizing coffee flavor

The flavor of coffee is affected by many factors, among which water quality is one of the most basic and important factors. Using filtered water or mineral water can avoid the interference of impurities and chlorine in the water on the flavor of coffee, ensuring that the original flavor of coffee is preserved.

Water temperature is critical to how well your coffee is extracted. Ideally, the water temperature should be between 90 and 96 degrees Celsius. Water that is too hot can make your coffee bitter, while water that is too cold can result in under-extraction and a bland taste. Adjusting the water temperature can significantly improve the taste and aroma of your coffee.

Brewing time also affects the flavor of the coffee. Brewing time that is too long can lead to over-extraction of the coffee, resulting in a bitter taste, while brewing time that is too short can result in a lack of flavor. Depending on the brewing method, controlling the brewing time properly can help achieve the ideal flavor balance.

The coarseness of the coffee grounds also directly affects the taste of the coffee. Coarsely ground coffee is suitable for use in a French press, while finely ground coffee is suitable for an espresso machine. The grinding size should be adjusted according to the equipment used and personal taste to optimize the flavor of the coffee.

Solutions to common coffee brewing problems

When brewing coffee, a common problem is that the coffee tastes too bitter. This is usually caused by brewing it for too long or the water temperature is too high. To solve this problem, you can shorten the brewing time or lower the water temperature slightly to ensure that the coffee flavor is not over-extracted.

If your coffee tastes too weak, it may be because the ratio of coffee powder to water is not correct or the brewing time is too short. Adjusting the ratio of coffee powder to water, increasing the amount of coffee powder, or extending the brewing time can make the coffee flavor stronger.

Another common problem is a lack of foam. For espresso machines, this may be due to the milk being too cold or the frother not being clean.
