A complete analysis of the coffee making process, from selecting coffee beans to perfect blending every detail

How to choose coffee beans that suit your taste

The type, origin and roasting degree of coffee beans will directly affect the taste of coffee, so when choosing coffee beans, you need to make a choice based on your personal taste preferences. First of all, the types of coffee beans are divided into two categories: Arabica and Robusta. Arabica beans taste softer and more delicate, with fruity and sour flavors, while Robusta beans tend to be bitter and strong, and are commonly found in strong espresso.

The origin of coffee beans also has a significant impact on the taste of coffee beans. Coffee beans from South America, such as Colombia and Brazil, usually have milder acidity and nutty and chocolate flavors; while coffee beans from Africa, such as Ethiopia, often have obvious floral and fruity aromas and higher acidity. Choosing an origin that suits your taste is the key to improving your coffee experience.

The degree of roasting is another important factor that affects the flavor of coffee. Lightly roasted coffee beans usually retain more of the original flavor of the beans, showing bright acidity and floral and fruity aromas; while deeply roasted coffee beans have a stronger taste, with a strong bitterness and smoky taste, suitable for coffee lovers who like strong flavors. When choosing, you can try different degrees of roasting according to your preferences.

Finally, when choosing coffee beans, you should also consider freshness. Freshly roasted coffee beans usually have a richer flavor, so try to buy coffee beans that are fresher. If possible, choose to buy the right amount of coffee beans each time to maintain its best taste.

The key influence of coffee bean grind size on flavor

The coarseness of the ground coffee beans has a crucial impact on the extraction effect of coffee, and can even determine the overall flavor of a cup of coffee. Simply put, the finer the grind, the faster the extraction speed, and conversely, the coarser the grind, the slower the extraction speed. Therefore, the choice of grind directly affects the acidity, bitterness and taste balance of coffee.

Different coffee brewing methods require different grind sizes. For example, a French press requires coarser ground coffee because coarser grounds allow water to flow through more evenly, thus avoiding over-extraction; while espresso requires a very fine grind because espresso machines require high pressure to force water through fine coffee powder to quickly extract strong flavors. If the grind is too coarse, the coffee may taste weak and fail to achieve the desired concentration.

Medium grinding is suitable for the common drip coffee brewing method. It allows hot water to pass through the coffee powder evenly, ensuring a stable extraction effect and avoiding the taste being too strong or too weak. At the same time, the grinding degree will also affect the aroma and flavor of the coffee. Too coarse or too fine will make the taste of the coffee unbalanced.

Therefore, choosing the right grinding degree is a key step in brewing a delicious cup of coffee. When choosing the grinding degree, you can adjust it according to your brewing method and taste preferences. The flavor differences brought by different grinding degrees are also part of the colorful coffee culture.

Water quality and temperature: the basis for perfect extraction

Water quality is an important factor affecting the flavor of coffee. The mineral content and impurities in the water will affect the taste of the coffee. Ideal coffee water should be clean, odorless and rich in minerals. The hardness of the water is directly related to the extraction effect of the coffee. Too hard water may cause the coffee flavor to be bitter, while too soft water may cause the taste to be thin and lack of layers. In order to ensure the best coffee experience, choosing purified water or filtered water is usually a good choice.

Water temperature is also crucial to the coffee extraction process. Too high a water temperature will cause the coffee to be over-extracted, resulting in bitterness and burnt taste; while too low a water temperature may lead to incomplete extraction and the taste will appear bland and weak. Generally speaking, the optimal brewing water temperature range is 90°C to 96°C. For different types of coffee and brewing methods, fine-tuning the water temperature can also bring different flavor experiences. For example, lightly roasted coffee is usually suitable for slightly lower water temperature to reduce excessive acidity; while dark roasted coffee can use slightly higher water temperature to better extract its strong flavor.

In addition, ensuring the cleanliness of the water source is a step that cannot be ignored. Chlorine and other chemicals in the water may affect the taste of the coffee and even destroy the aroma of the coffee itself. Using filtered water or mineral water can usually effectively avoid this problem and maintain the original flavor of the coffee. If conditions permit, you can use water quality adjustment equipment specially made for coffee to ensure that the water quality meets the standards.

The golden ratio of coffee powder and water and brewing techniques

The ratio of coffee powder to water is a key factor in determining the strength of a cup of coffee. Generally, the ratio of coffee powder to water can be adjusted according to personal taste, but most coffee lovers recommend a basic ratio of 1:15 to 1:18. This means that for every 15 grams of coffee powder, about 225 ml of water should be used. If you want a strong taste, you can increase the amount of coffee powder appropriately, while if you prefer a lighter taste, you can reduce the amount of coffee powder.

Different brewing methods require different ratios of coffee powder to water. In drip coffee, medium-ground coffee powder is usually used, and the ratio can be maintained at around 1:16. The water flow rate is slow, which can ensure uniform extraction and a balanced taste. The French press is suitable for coarser coffee powder, and the ratio can be increased moderately, such as 1:15, so that a richer flavor can be obtained. The French press method extracts more oil and aroma through a longer soaking time, bringing a richer taste.

For espresso, the coffee powder grinding degree is required to be fine, and the ratio is generally about 1:2. The espresso machine uses high-pressure water to quickly extract coffee, so the ratio of coffee powder to water is tighter, which can extract a strong and strong flavor. When operating, you need to ensure that the coffee powder is compacted evenly, so as to avoid uneven extraction and ensure the stability of the coffee taste.

Each brewing method has different operating points. Drip coffee focuses more on stable water temperature and uniform extraction, French press requires controlling the soaking time, and espresso relies on high-pressure extraction. When adjusting the coffee ratio, in addition to personal taste, mastering the skills of each method is also the key to improving coffee quality.

Control the extraction time and adjust the coffee flavor

The extraction time directly affects the taste and flavor of coffee. Too short an extraction time will result in insufficient extraction of coffee, making it sour and weak in taste; while too long an extraction time may over-extract bitterness and unpleasant flavors. Therefore, precise control of the extraction time is the key to regulating the acidity, bitterness and overall balance of coffee.

Different brewing methods have different requirements for extraction time. For example, a French press usually requires a longer extraction time of about 4 to 5 minutes. This time can fully extract the oils and aroma of the coffee, bringing a rich taste. If the extraction time is too short, the coffee will be bland; if it is too long, it may produce too much bitterness and astringency.

In drip coffee, the extraction time is usually 3 to 4 minutes. The water flow through the coffee powder needs to be uniform and stable. Too fast a water flow may lead to insufficient extraction, resulting in a sour taste; while too slow a water flow may lead to over-extraction, and the bitterness of the coffee will be more prominent. Therefore, it is crucial to adjust the water flow rate and water temperature during the drip process.

The extraction time of espresso is short, usually between 25 and 30 seconds. In this short time, high pressure extraction can quickly extract the strong coffee flavor. If the concentration time is too long, it will produce too much bitterness and excessive release of oil, affecting the balance of the overall flavor.

Adjust coffee by tasting to create your own unique taste

Coffee tasting is an important part of evaluating coffee quality. It helps us understand the acidity, bitterness, sweetness and overall balance of coffee. First of all, when tasting, pay attention to the color and aroma of coffee, and use your tongue to feel the different flavors. Excellent coffee usually has obvious aroma layers and a mellow taste, while a taste that is too single or sharp may mean that the coffee extraction is unbalanced.

During the tasting process, knowing how to adjust the taste of coffee is the key to improving the experience. If the coffee is too sour, you can consider reducing the extraction time or adjusting the coarseness of the coffee powder to avoid excessive extraction and excessive sourness; if the coffee is too bitter, you can reduce the water temperature or adjust the ratio of coffee to water to make the taste smoother.

For coffee lovers who prefer sweetness, you can balance the acidity and enhance the sweetness by increasing the amount of coffee powder or using medium-deep roasted coffee beans. Proper roasting and extraction time can also significantly improve the flavor of coffee, making it smoother and richer. Common adjustment techniques include fine-tuning the water temperature, grinding degree, and extraction time, which can help you find the coffee recipe that best suits your personal taste.

By constantly tasting and adjusting, you can gradually master the art of coffee blending and create your own perfect coffee. Everyone has different preferences for the taste of coffee, and the process of tasting and adjusting is also a journey of exploration and enjoyment.

Common coffee making mistakes and solutions

There are some common mistakes in the coffee making process that can lead to a final cup of coffee that doesn't taste as good as you'd like. Knowing and avoiding these mistakes can help you improve the quality of your coffee. A common problem is over-extraction, which occurs when the coffee grounds and water are in contact for too long, resulting in excessive bitterness and astringency. This usually happens when using a grind that is too fine or when the extraction time is too long. The solution is to reduce the extraction time or grind the coffee grounds a little coarser to avoid over-extraction.

Another common mistake is using too coarse or too fine coffee powder, which results in uneven extraction. For example, using too fine coffee powder in a French press may cause water flow to become blocked, resulting in incomplete coffee extraction and a sour taste. On the contrary, when using too coarse coffee powder to brew espresso, the water flows too fast, resulting in incomplete extraction and a weak coffee taste. The correct method is to adjust the grinding degree according to different brewing methods, using coarse powder for French press and fine powder for espresso.

In addition, water temperature control is also a common mistake. If the water temperature is too high, it is easy to over-extract and bring unnecessary bitterness; if the water temperature is too low, it may lead to insufficient extraction and the coffee tastes bland. Generally speaking, the ideal water temperature range is 90°C to 96°C. If there is no temperature control equipment, you can reach the optimal temperature by letting the water cool slightly for a few seconds after boiling it.

Finally, if the ratio of coffee to water is not mastered, it may also affect the flavor. Too much coffee powder will lead to over-extraction and a strong taste, while too little coffee powder will lead to under-extraction and a weak coffee taste. It is recommended to follow a basic ratio of 1:15 to 1:18, and adjust it slightly according to personal taste.
