Espresso Quality Assessment-Coffee Flow Rate
The flow rate of espresso directly determines the taste of Espresso. Too fast flow rate will make the essence of coffee not dissolved in water, but the water has already passed through the coffee powder, resulting in coffee tasteless; too slow flow rate will make the essence and dregs of coffee melt into the water, resulting in coffee with obvious burnt astringency or irritating bitterness. The tail of a rat is something like this.

How to calculate the extraction rate of coffee? What is the gold cup extraction rate, teach you to adjust the taste of coffee.
SCA gold cup standard extraction rate = water-soluble coffee substance / coffee powder amount * 100%; concentration = water-soluble coffee substance / coffee liquid weight * 100%; extraction rate = coffee liquid weight * concentration / coffee powder content * 100%; extraction rate indicates the proportion of the extracted coffee substance to the total coffee bean weight. The extraction rate is between 18% and 22%. The concentration indicates the coffee substance extracted from a cup of coffee.

Understanding the extraction rate is the basis of making a cup of espresso
What I want to tell you in the article is that the concept of extraction rate is not difficult, and there is little relationship between extraction rate and concentration, and extraction rate is very important, which you need to know as a barista. The article will mention several questions: (1) the concept of gold cup criterion; (2) the relationship between extraction rate and concentration; (3) knowing the extraction rate, it is meaningful for us to adjust the grinding degree and powder quantity every day, and then we can make it better.

What is the effect of ambient temperature on coffee roasting? how to use the rate of environmental change to improve the baking curve
The environmental change rate is not as good as the rising rate, the bean temperature and the environmental temperature are better. But it is even as important, or even more important. It helps to predict the temperature of the drum, which in turn helps to maintain control during the baking process. What is ambient temperature? If you don't know the ambient temperature first, you can't understand the rate of environmental change. This is the temperature of the air in the drum of the baking machine measured using a thermocouple.

How to calculate the extraction rate of hand brewed coffee? How do you know if a cup of coffee is too good?
Coffee beans are not all soluble in water. Only 30% of the substances in a coffee bean are soluble in water, while the remaining 70% are insoluble substances such as wood fibers. Therefore, the maximum extraction rate of coffee is only 30%, but in most cases, the extraction rate of coffee can not be so high, but how can we know the specific extraction rate!
