Among the many brewing methods, hand-brewed coffee can be said to be the most popular coffee brewing method at present, which is simple, easy to learn, easy to control, and the taste can be accepted by most people. But there are also many friends who are not sure how to find the right taste when making it. Now let's briefly introduce what factors affect a cup of hand-brewed coffee and how influential it is.

First of all, let's start with the supplies and tools you need.

Consumables: coffee, filter paper, water

Utensils: cups, pots, water injection appliances, weighing appliances, timing tools, thermometers, grinding tools

Let's start with the most important thing, the hand-brewed coffee beans themselves:

We make coffee, not orange juice, not green tea, so the coffee itself determines the basic taste of this cup of coffee. For example, whether this coffee is tanned or washed, it comes from Asia, Indonesia, Colombia in South America, or Ethiopia in Africa. When the coffee is confirmed, the taste in your cup is actually 50% sure. This is the most important part.

The second is the grindness and uniformity of hand-washed coffee beans:

The degree of grinding thickness of coffee directly determines the amount of coffee substances extracted in the brewing process. In unit time, the thicker the coffee substance is, the more difficult it is to be extracted, and the finer the coffee is, the faster the extraction speed is. Reflected in the taste, it will be lighter or stronger. Under normal circumstances, our coffee mill can not be absolutely uniform, after you choose the thickness, a certain proportion of the powder that does not meet your requirements will be ground out, which, if appropriate, will increase the layering of the coffee flavor. and excessive uneven coffee taste will make the coffee taste "out of control".

The third is the water quality and temperature of hand-brewed coffee:

The water quality varies in different parts of the country, and it is generally believed that the water quality in the north is not as good as that in the south. In this way, we still have two choices for making coffee water, tap water treatment water and purchased bottled water. The so-called tap water treatment water is tap water treated by a water softener, water purifier or pure water machine. this kind of water can be used to make coffee and tastes much better than using tap water directly. The other is to use purchased mineral water, mineral water and pure water to make coffee. Cost is not what we are thinking about today, so we can basically default to a more expensive way of handling, perhaps, we are talking about the possibility that it will taste better. However, what we want to emphasize here is that "pure" water is not suitable for making coffee, that is, water treated by pure water or purchased pure water. It is true that this kind of water does not have water alkali, but due to the lack of minerals in the water, the taste of the water itself is lower, and coffee made from pure water tends to taste stiff and lack a sense of layering. Why, I am not a chemist. I really can't say one or two.

On the other hand, water temperature is also an important index that affects the taste of coffee. When I personally make coffee, I am used to using a water temperature of about 90 degrees, which is, of course, in line with my grinding thickness. You don't have to be so precise, in fact, you can fix a personal habit, such as standing for 1 minute or 1.5 minutes after the water is fully boiled, of course, you have to adjust the temperature in the room according to the temperature in the room. There is estimated to be a temperature difference between winter and summer.
