The importance of uniform grinding may often be ignored by ordinary people. Often people do not know that it is actually the purchase of a bean grinder.

Machine), it should be more important than choosing a coffee maker.

The impurities, even the bitter taste will come out. If the coffee bean is ground too thickly, the quality of the coffee bean itself is still delicious.

Hidden inside the beans, where the hot water is out of touch, the brewed coffee will not be able to have enough delicious aroma.

Generally speaking, a good grinding method should have two basic principles:

(1) the equipment used should be selected to adjust the correct and suitable grinding coefficient.

The range of grinding degree (grinding coefficient) can be roughly divided into several types:

● espresso grinding Espresso Grind: more suitable for the use of espresso machine the fine degree of grinding is quite sensitive.

● Turkish grinding Turkish Grind: more suitable for Ibrik pots this kind of appliance is quite rare in Taiwan, but

This kind of coffee utensils can still be found in some countries in the Middle East and Europe.

● rough grinding Coarse Grind: more suitable for filter kettles.

(2) the temperature produced during grinding should be low.

No matter what kind of bean grinder is used, it will also produce heat due to friction in operation, and most of the excellent substances have high quality.

The degree of volatility, so at the time of grinding, the heat is produced, and at the same time, it also increases the rate of volatilization, so that the mellow smell will be

Lost in grinding.
