Gold Cup Gold Coffee Theory Practical Edition:2012 with Golden Ratio

To drink 300ml of coffee, how many grams of coffee beans should I use? Gold cup gold coffee theory easy to remember practical version!

Simple version (coffee cup capacity *1.2%)/20%= desired coffee beans

Very simple version Coffee cup capacity *0.06= coffee beans required

Elegant version Coffee cup capacity *6.18%= coffee beans required

To drink 300ml of coffee, how many grams of coffee beans should I use? 300*0.0618=18.54g Simple counting 300*0.6=18g

The following is an explanation of the content. If you want to see it, you can see it. If you don't see it, skip it!

Gold cup theory is useful, scientific data guidance is useful most of the time; only by reducing the variables between each cup of coffee can you learn the skills of brewing a good cup of coffee faster.

Gold cup coffee theory is good, but some coffee students will look confused, come to a simple.

Gold cup gold coffee theory simplified the point is 20% coffee extraction rate, that is, coffee powder brewing weight reduced to 80%, 20% of the total amount of coffee oil is extracted; the appropriate coffee concentration is 1.2%, that is, 100 ml coffee oil extract is 1.2%. For ease of memory, the 20% and 1.2% data fluctuates by 10% as the normal error value.

Therefore, there is a simple calculation formula: coffee capacity *0.06= need to put coffee beans, add coffee residue in the coffee grounds after extraction, beautify the data to 0.0618! What is this, the golden section!

6.18%

In fact, there is also a golden section point, according to the gold cup gold coffee theory, the general roast coffee beans contain extractables for more than 30%, but the degree of extraction to six or seventy percent is appropriate, simplified coffee powder extraction rate is about 20%.

To drink 300ml of coffee, how many grams of coffee beans should I use?

300*0.0618=18.54g

Simply count 300*0.6=18g

Of course, the practical version of the gold cup theory does not take into account many possible errors. Generally speaking, science is necessary, but it cannot be too scientific, and it can never be completely scientific and accurate.
