First, read the English article below.

For a fresher, more flavorful coffee, you should buy fresh coffee beans and grind them yourself, rather than buying pre-ground coffee. A coffee's flavor comes from delicate flavor compounds within the cells of the coffee bean. When ground, the coffee bean's interior is exposed to the air and, over time, will react with it, causing the coffee to lose some of its aroma.  Be sure to store your coffee beans in an air-tight container. Coffee has odor-absorbing properties - that's why coffee grounds can substitute for baking soda in the fridge. Unfortunately, this also means that if your coffee isn't kept sealed in an air-tight container, you may have garlic-y coffee. Coffee aficionados disagree on whether to store coffee beans at low temperatures. Some recommend keeping coffee beans in the fridge if they will be used within a week and transferring any beans that won't be used for a few weeks to the freezer. Others prefer simply to keep them in a cool, dark place. Different coffee brewing methods may require coarser or thicker grinds for optimum flavor. Because ground beans exchange their flavor compounds with water, changing the coarseness (and thus the overall surface area that can be touched by water) of the grounds can affect the final flavor. Generally, the more time that the brewing method requires the coffee and water to be in contact with each other, the coarser the grind. For normal "drip" coffee makers as described in Part One above, a medium grind (like you'll find for most pre-ground coffee) is usually fine. If you're using a more exotic brewing method like a french press or an aeropress, consider consulting a coarseness chart like the one available here: http://www.coffeeconfidential.org/grinding/ground-coffee/ . For brewing processes, water should be around 195–205 °F (91–96 °C), or just below boiling. Colder water won't extract enough flavor from the coffee beans, while hotter water can scald the coffee, affecting the taste.  If you are boiling your own water for your coffee, allow the water to come...
