How to calculate the powder ratio of hand-brewed coffee beans?

Since the emergence of the wave of boutique coffee, hand-brewed coffee has become the most important way of brewing. The general scientific theory of coffee brewing emphasizes several basic factors:

1. Degree of grinding

In general, the grinding degree of hand-brewed coffee is recommended to use the size of fine granulated sugar, and the screening rate of 20mm is up to 70%. In the industry, this kind of grinding cup becomes the cup to measure the grinding degree, which is recognized by the industry.

2. Ratio of powder to water

The powder-to-water ratio literally means the ratio of coffee powder to water. Coffee extraction is pleasant only at the right concentration and Tds. Powder-to-water ratio is generally recommended to use the powder-to-water ratio at 1:15, that is, it takes 15 grams of water to brew 1 gram of coffee powder. It is generally recommended that the amount of coffee powder is 15 grams and the amount of water is 240 water.

3. Cooking utensils

Different brewing utensils will affect the extraction effect of coffee. Take the common V60 hand filter cup as an example, the coffee liquid brewed by it is rich in layers, which can reflect the characteristics of coffee beans.

4. Water quality

Not all water can be used to brew coffee. The American Fine Coffee Association recommends that the tds of water is 125-175ppm. Coffee brewed by water in this range is easier to meet the taste of the general public, while friends who generally brew at home can choose mineral water, and their tds is generally in this range.
