How do you calculate the ratio of water powder to hand-brewed coffee? what is its principle? which powder tastes better than the coffee made?

With the development of boutique coffee up to now, in order to enable the public to brew a cup of delicious coffee, accompanied by the maturity of brewing theory, the so-called brewing theory is to regularize and theorize the steps of our daily coffee brewing.

When we brew coffee, water temperature, powder-to-water ratio, grinding degree and time are all factors that determine the taste of a cup. The so-called powder-to-water ratio is the ratio of coffee powder to water, which is the main component of coffee liquid and a solvent with strong solubility. The higher the powder-to-water ratio is, the higher the amount of water in the coffee liquid is, the less the coffee content is, and the lower the powder-water ratio is, the more coffee it contains. The flavor of the coffee liquid will be more concentrated, the concentration will be relatively higher, and the generally recommended powder-to-water ratio is 1:15, in this powder than the brewed coffee liquid is more in line with the public taste.
