Here, I would like to make a few suggestions. When buying coffee, it is best to buy coffee beans instead of ground coffee powder. Although they are all the same in nature, the actual situation is that they have been ground. Good coffee powder is very easy to oxidize and is not easy to preserve. Even those coffee powders that seem to last for a long time are actually added with a lot of preservatives, which will greatly affect the coffee that is brewed later. The taste, so if you want to make a good cup of coffee, the best and most correct way is to grind the coffee on the spot before brewing the coffee, in order to maintain the mellow taste and taste of the coffee to the greatest extent. Coffee beans can be kept for about a month, but if it is coffee powder, it should not be more than five days.

Here, give some suggestions when choosing coffee beans.

The first point is to notice the original habits of coffee beans. Coffee beans can't be exposed to strong sunlight, and they can't be put together with things with volatile properties. These two points indicate that the coffee beans are best sealed. The light box or jar is good inside.

The second point is to distinguish the beans you need according to the color of the coffee beans.

Then the colors are different. The flavor of the coffee itself will change accordingly. The soy taste of the lighter coffee beans is very heavy, but as the baking degree deepens, the sourness in the coffee beans will slowly It disappears, and the bitter taste will rise step by step. Basically, we divide the baking degree of coffee beans into shallow baking, medium baking, and deep baking. These three main categories can be subdivided into eight small ones. Classes, listed in detail are the following eight levels, from shallow to deep, shallow baking, meat-style baking, medium-baked, deep-baked, urban baking, full-baked baking, French baking, Italian baking, in which the degree of Italian baking is the deepest.

The characteristics of the taste, so try to buy fresh coffee beans, but for the habit of coffee beans, do not throw away the deteriorated coffee beans, as a desiccant and deodorant for refrigerators or wardrobes is a good choice, environmentally friendly and no pollution.
