How to grind beans? The following article will give you a quick understanding of the eyebrows of ground beans in the simplest and most straightforward way.

Fresh grinding and cooking, the flavor is the best

After roasting, coffee beans begin to undergo a series of chemical changes, releasing flavor and emitting large amounts of carbon dioxide. Carbon dioxide can help coffee beans resist oxygen and moisture, avoid rapid decay, and thus maintain the most complete flavor of coffee beans.

Coffee beans should be ground and cooked with the best flavor.

Therefore, once the coffee beans are ground into powder, a large amount of flavor will be lost, and fresh grinding and cooking is the best choice. For the best taste of coffee, we only recommend you to buy coffee beans with one-way valve packaging.
