Concentration: the ratio of grams of coffee beans to milliliters of hot water is 18.18, that is, 8.25 grams of coffee beans are ground and extracted with 150 ml of hot water, or 9.9 grams of coffee beans are extracted with 180 ml of hot water, or 11 grams of coffee beans are extracted with 200 ml of hot water. In other words, as long as the weight of coffee beans and hot water milliliter is 1RU 18.18.

The American Fine Coffee Association has set the ratio of coffee beans to hot water at 1.15% 18.18 because the concentration of the extraction happens to fall in the middle of the total body solubility of 1.15% 1.35% as specified in the Golden Cup criteria.

Basically, the concentration required by the cup test is lighter than that of ordinary follicular coffee, so that the coffee is too strong and the taste spectrum is tangled, so it is not easy to tell the good from the bad.

It is inevitable that ground coffee will produce heat, but the heat will vary depending on the mechanism of grinding beans. Bean grinders grind coffee beans in two ways: one is to grind coffee beans with two grinding plates engraved with shallow grooves, which we call parallel grinders, and most manual bean grinders fall into this category. The other is represented by the shredder, and the coffee beans are cut by two sets of rollers with sharp blades that bite perpendicular to each other, which is the so-called tapered blade grinder.

It is generally believed that slow grinding with a manual parallel bean grinder will not produce heat, in fact, on the contrary, the type of friction with a disc blade is easy to produce heat. On the other hand, the tapered bean grinder can minimize the friction heat produced by grinding coffee powder. The reason is that the tapered blade is ground quickly with a longer blade process, and the tapered blade takes less time and has a lower heating rate at the same thickness.
