How to scale the coffee grinder? how to deal with cat poop and coffee beans?

Roughness can control bitterness is a good way to control bitterness, because the finer the grinding, the higher the extraction rate, the easier it is to extract high molecular weight astringent bitter substances such as chlorogenic acid, quinic acid, caffeine and carbides.

On the contrary, if the grinding is too rough, the lower the extraction rate is, the more difficult it is to extract the astringent bitter substance with high molecular weight, but the sweet taste with middle molecular weight may remain in the coffee grounds because of insufficient extraction, which is a waste. The scale is not immutable. Do not use the same grinding scale for playing coffee. If you know that the density and baking degree of each bean are different, the required scale will not be the same. The scale of very hard beans or shallow roasting can be slightly adjusted to be finer, and the deep roasting can be adjusted thicker.

If you think a bean tastes bitter and salty on scale # 3, this is excessive extraction, which can be adjusted to # 3.5 or # 4, which will significantly improve the bad taste spectrum, and vice versa. In addition, the bean grinder should be diligent in maintenance, regularly remove the knife head and remove the oil dirt inside. The knife head is consumable, and it will be dull every 800 to 1000 pounds. Remember to replace it, otherwise the grinding particles will be half-thick and half-thick, which will cause uneven extraction and damage the good flavor of coffee.

Bean grinders are generally classified by coffee extraction, which are divided into two categories: single coffee grinder and Italian coffee grinder! According to the structure of the grinding plate can be divided into flat knife, cone knife, ghost teeth three categories! You can break up manpower and electric power according to the way you work. But no matter what category, my personal advice is to buy the best bean grinder that you can afford.

As for flat Dao, it has the largest quantity on the market. Whether it is a single bean grinder or an Italian bean grinder. Whether it is the top commercial German Mehdi EK43 or the mid-range MAZZER MAJOR, or the Eureka MMG designed for home use. Flat knife grinder generally has a clear positioning, either the Italian brand MAZZER as the representative of the pure Italian grinder, or the German brand Mahdi as a single product grinder with table (some models can also be compatible with Italian coffee). Because of the difference in knife pattern design and adjustment design, most Italian brand Italian coffee grinders can only grind the fine powder suitable for Italian coffee, but not for the coarse powder of single coffee! In the field of flat knife, the quality of the product is directly proportional to the grade of the bean grinder and the diameter of the grinding plate. So much so that there is a famous saying in the coffee world that the diameter of the grinding disc of a flat knife is the truth.
