1. Grindability of hand-brewed coffee beans

One of the secrets to brewing delicious coffee is the degree of grinding of coffee powder. The degree of grinding of coffee powder is wrong, not to mention a delicious cup of coffee, it may not be extracted at all. Assuming that the grinding degree of the mocha pot is used in the hand dripping filter pot, it will be difficult to swallow because the taste is too bitter, and the coffee powder will plug the filter screen, causing the extraction time to be too long, or the water will overflow the filter cup. On the other hand, if the grindness of the hand dripping filter pot is used in the mocha pot, it will not be able to extract the strong espresso, but will become a liquid with little coffee aroma, and it may also be because the coffee powder particles are too thick. The coffee liquid cannot be extracted from the lower pot to the upper pot and seeps out from the side of the pot. From this, it can be seen that each kind of coffee utensils has an appropriate degree of grinding, and most coffee bean shops will tell them the appropriate degree of grinding of the utensils, or to match the degree of grinding needed to grind coffee beans. However, in order to make the coffee fresh, it is recommended to buy a household bean grinder and grind the beans before brewing.

Italian espresso utensils such as mocha pots or ROK are tools with a fixed degree of grinding and do not have much choice. However, if the degree of grinding is adjusted within the permitted range, the flavor of the extracted coffee is also different. Hand dripping filter pot or French double-layer filter kettle, relatively speaking, the range of grinding degree is relatively wide, and the coffee flavor can be adjusted according to the different grinding degree. For example, a French double-layer filter kettle is used to extract coffee. If the coffee beans are ground thicker than usual, the taste spectrum will be sour; if they are finer than usual, they will be bitter.

Even if you use the same coffee beans, the same utensils, and the same way to extract coffee, the coffee flavor will vary greatly because of the different degree of grinding. If you want to change the taste of coffee, you can try to adjust the degree of grinding.

Different degrees of grinding will affect the flavor of coffee.

two。 Adjust the water temperature and control the taste of hand-brewed coffee

Because of different water temperatures, coffee with different characteristics and flavors will be extracted. There are usually three kinds of water temperature when extracting coffee: 1. Use water below room temperature, 2. Use hot water, 3. Coffee is brewed with water.

Coffee extracted with water below room temperature usually takes as little as 2 hours to more than 24 hours in order to fully extract the coffee ingredients. The coffee extracted in this way is a bit like wine, which can be preserved for a relatively long time. The longer the time is, the softer the taste will be, but it will go bad if you put it for too long. The "cold bubble method (Cold Brew)", known as ice drop coffee, belongs to this method.

Coffee extracted with hot water is the most common way. The general water temperature is between 80 and 95 degrees Celsius. The lower the temperature is, the stronger the sour taste is, and the bitter taste also appears. The taste of coffee extracted by different water temperature varies greatly, so even if you use the same coffee beans and the same grinding degree, different water temperature will bring different feelings. Therefore, people who like to use hand drip filter pot or French filter pressure pot for a long time have their own preferred water temperature.

Coffee is brewed with water by extracting coffee at a temperature close to 100 degrees Celsius. Turkish coffee pots or siphon pots fall into this category. Relatively speaking, you can drink stronger coffee, and the water temperature is always fixed at 100 degrees Celsius, it is easier to maintain the consistent flavor of coffee.

Adjust the water temperature can control the taste of coffee, too bitter, the water temperature is lower; too sour, the water temperature is higher. Remember, as long as you know how to adjust the water temperature, you can change countless different flavors of coffee.

3. The material of hand coffee filter-paper vs fiber (cloth) vs solid (stainless steel series)

A cup of coffee contains coffee liquid, coffee oil, and coffee powder. When extracting coffee, the ingredients are different according to the material and type of filter used, so using different filters, the flavor and taste of the extracted coffee are also very different.

Generally speaking, filter paper will filter out more coffee powder and coffee oil, and can extract coffee that feels cleaner. The filter cloth made of fiber is the filtering method used by most people before the appearance of filter paper. it can filter coffee powder, but it will not filter out coffee oil, so the extracted coffee tastes softer. Therefore, many coffee lovers regard the coffee extracted with filter cloth as the best coffee. However, after the coffee is extracted, the filter cloth should be washed, hung, and kept with clean water, because it is too troublesome to popularize the public. The stainless steel filter, which will extract all the coffee powder and coffee oil, can preserve the original flavor of coffee, and the filter is easy to save and can be used permanently.

Most coffee utensils have their own filters, but it is up to the extractor to decide which filter to use, such as hand drip coffee, love pressure, ice drop coffee and so on. Put aside the convenience, generally want to drink cleaner taste of coffee, use filter paper; if you want to drink supple taste of coffee, use filter cloth; if you want to drink the original flavor of coffee, you can choose stainless steel filter.
