The core process of the extraction principle is as follows: 1 grind coffee beans and increase the surface area of coffee in contact with water

When it comes to brewing coffee, there are many kinds of coffee-making equipment on the market and different methods. But in terms of the principle of coffee extraction, it's all the same. The core process of the extraction principle is as follows: (1) grinding coffee beans to increase the surface area of coffee in contact with water; (2) fully soaking coffee powder in aqueous solution and hydrophilic dissolution of coffee essence; (3) separating coffee solution and coffee grounds

Italian Coffee making course: explanation of extraction area and extraction time of Coffee Powder

Italian Coffee making course: explanation of extraction area and extraction time of Coffee Powder

There are several variables that can be adjusted for extraction, the two most important of which are extraction time and extraction area. In any way of cooking, these two variables are closely related and inseparable, and you can't change one variable without touching the other. Extraction time (Time) if you increase the contact time between water and coffee powder, more flavors will be extracted.

If you increase the contact time between water and coffee powder, more flavor substances will be extracted. If the water comes into contact with the coffee long enough, the extraction will continue until no more is dissolved. All we have to do is to find out when the extraction reaches the best flavor value. With regard to the variable of extraction time, there are actually two different aspects that need to be considered separately.

Coffee grinder and coffee maker like coffee

The main results are as follows: 1. Select the grinding degree suitable for cooking method. Adjust properly according to the characteristics of the bean grinder and the degree of baking. Generally speaking, the shorter the cooking time, the more the coffee powder must try its best to expand its surface area to contact with the water, and the finer the particles required; on the contrary, the longer the cooking time, the thicker the grinding particles must be, so as to avoid the extraction of unnecessary impurities. 2. The temperature produced during grinding

Why does Fine Coffee emphasize freshly ground Coffee

Why does Fine Coffee emphasize freshly ground Coffee

If the diameter of the coffee powder is doubled, the volume of a single particle is reduced by 1 × 8, and the surface area of the corresponding total coffee powder is doubled. After the coffee bean is ground into coffee powder, its surface area increases exponentially, and the area of contact with air increases hundreds of times. The extremely important acidic and volatile fats in roasted coffee beans once exposed to air

Why emphasize freshly ground coffee? When you smell coffee powder, it indicates that it is deteriorating and the essence of coffee is decreasing. If the diameter of coffee powder is doubled, the volume of individual particles is reduced by 1/8, and the surface area of the total coffee powder is doubled accordingly. After coffee beans are ground into coffee powder, its surface area increases exponentially, the area in contact with air.
