Raw coffee beans contain sour ingredients such as citric acid, malic acid, quinic acid and phosphoric acid, but these are not the main sources of sour taste when drinking coffee. The acid produced during baking is the main source of sour taste. Raw beans produce a series of chemical reactions during baking to form new acids. The most important thing is that chlorogenic acid is decomposed to form quinic acid and oligosaccharides.

For all kinds of coffee extraction methods, whether the grinding degree is appropriate or not can directly determine its success or failure. The grinding of coffee beans seems complicated, but in fact there is still a regular pattern. Different utensils, even the same utensils and different coffee beans, need to be ground.

The first one in the picture above is the alp drum, which should be evenly stirred, but it is very troublesome for us to design this kind of design. The second is hottop's drum, which feels that the baking of small grams is very good, especially the middle slide can not only stir beans from separate parts, but also be good.

Because although the extraction time is directly related to the relationship between extraction rate and concentration, their relationship is not necessarily proportional. We still return to the original two purposes, get the reasonable extraction rate and get the proper concentration.
