The thickness and grinding degree of hand-washed coffee beans differ in taste.

There are all kinds of bean grinders on the market, and a good bean grinder can ensure that the coffee powder is evenly ground. If the coffee powder is uneven and the fine powder is too much, it will make the coffee taste not "pure".

What is the suitable thickness of hand-brewed coffee beans?

The answer is: moderate grinding, the size of granulated sugar. If the coffee powder is too thick and the hot water flows too fast, it is difficult to extract the aromatic substances from the coffee. If the coffee powder is too fine, the filter is easy to clog, resulting in water and powder soaking time is too long, coffee will appear bitter, astringent taste.

Many people choose ground coffee powder for convenience, or grind a lot at one time and put it in the refrigerator. In fact, "fresh grinding" is the first condition of good coffee, it ensures the taste of coffee. When the coffee is ground into powder, the oxidation rate of the coffee powder is accelerated, and the aroma begins to lose in 40 seconds. If the aroma of the coffee powder is seriously lost, the flavor of the natural coffee will disappear. if you care about the taste, don't ignore the water used to brew the coffee. 98% of the ingredients in a cup of hand-brewed coffee are water, and the range of soluble matter (TDS) in the water is preferably between 100-250ppm. It is not recommended to use pure water to make coffee. Coffee made with pure water often tastes dull and lacks a sense of hierarchy. But do not use mixed brand mineral water or mixed brand barreled water, once there is a strange smell in the water, it will be more obviously magnified and reflected in the coffee. (you can choose mineral water from famous brands such as Xafu.

(1) Coffee filter paper is sold in many places. It is recommended to choose unbleached brown filter paper and wash it slightly with hot water before brewing. UCC, Tiamo, Kalita, Hario, pearl horse and other brands are the love of many coffee fans.

(2) generally speaking, the filter cup can be divided into two types: cone-shaped filter cup and ladder-shaped filter cup. the flow rate of cone-shaped filter cup is fast and the extraction time is short, so it needs better technology to control. Beginners, it is suggested that the ladder-shaped filter cup should be used to brew first. Hario, Kalita and Tiamo are all good brands.

(3) apart from the filter paper, there are metal strainer and flannel to choose from. The metal filter can flush out the oil of the coffee, and the flannel filter cloth can extract more aromatic substances because it has been filtered for a long time, and the taste is stronger.
