How to choose good coffee beans? Basic knowledge of coffee

Coffee beans are a kind of agricultural plant that produces coffee. We usually choose coffee beans to make all kinds of coffee. Coffee beans are the raw materials used to make coffee, so the quality of coffee is determined by coffee beans. So the quality of coffee beans is a key point in determining whether coffee is good or bad. So how to choose the right coffee beans? Let's get to know it together.

1. When we choose fresh coffee beans, we need to pay attention to whether the color and size of the coffee beans are the same, and the color of the outer skin of the coffee beans is shiny, and it has a strong flavor. Whether the coffee beans are fresh or not is the key to affect their quality. If coffee beans lose their fragrance or have a stale taste, they are not suitable for purchase.

2. When we choose the coffee beans we use, the coffee beans that have just been fried are not suitable for drinking immediately, because the aroma of the coffee beans that have just been fried is not very good, so it is generally necessary to store the fried coffee beans for a week. At this time, the coffee beans are the freshest, and the coffee has the best aroma and taste.

3. The purity of coffee is also a consideration in coffee selection. Usually grab a handful of coffee with your hand, and then see if the color of the beans is the same, the size or shape of the beans is the same, and avoid mixing the beans with other poor beans.

4. When selecting coffee beans, you should choose to pay attention to whether the coffee beans go bad. It is generally applicable to the coffee beans that are too hot to produce oil, but if you do not stir-fry the coffee beans with oil in this way, it means that the coffee beans have gone bad. Not only the smell of the coffee beans will be bad, but also the taste will be bad.
