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

(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.
