How to select coffee beans how to select coffee beans high quality coffee beans distinguish the roasting methods of coffee beans

If you want to make a good cup of coffee, in addition to your own technology, the most important thing is how to select high-quality coffee beans and how to better preserve them. Here, extract Coffee gives some advice on how to choose coffee beans:

The first point is to pay attention to the original habits of coffee beans. Coffee beans should not be exposed to strong sunlight and should not be put together with volatile things. These two points show that coffee beans are better sealed in dark boxes or jars.

The second point is to distinguish the beans you need according to the color of the coffee beans. Whether they are beginners or friends who have been in the coffee circle for a long time, you still need to be familiar with these basic knowledge. Coffee beans will show different colors due to different roasting degrees. The flavor of coffee itself will also change. The sour taste of lighter coffee beans is very strong, but with the deepening of roasting, the sour taste of coffee beans will slowly disappear, while the bitterness will rise step by step. Basically, we divide the roasting degree of coffee beans into light roasting, moderate roasting, and deep roasting. These three main categories can be subdivided into eight subcategories. It is listed in detail as follows: shallow baking, meat baking, moderate baking, deep baking, urban baking, full-process baking, French baking, Italian baking, among which Italian baking is the deepest.

The third point is to learn to check the shelf life of coffee beans, coffee beans begin to oxidize after baking, just like aluminum powder, although the speed is not so fast, but the principle is the same. And coffee beans have the characteristics of moisture absorption and flavor absorption, so try to buy fresh coffee beans, but for this habit of coffee beans, do not throw away coffee beans that have gone bad, as a desiccant and deodorant in refrigerator or wardrobe is a good choice, environmentally friendly and non-polluting.

The fourth point is how to distinguish whether coffee beans can continue to be used or whether they go bad and have to be abandoned. Apart from looking at the color, what you should believe most here is your nose. Fresh coffee beans smell rich in the original aroma of coffee, while coffee beans that are stale or over-oxidized will be poor or basically tasteless, and serious ones will have a musty smell. The smell of earthy and iodine may even have the taste of fermentation.

Fifth, and the most essential point, directly press or taste the coffee beans with your hands, because when you squeeze the coffee beans with your hands, the good coffee beans will not only give off an overflowing fragrance but also be accompanied by a crisp crack sound. Further, you can put the coffee beans into your mouth and bite them open. If the sound of cracking is crisp and short, then it shows that the coffee beans are not wet. Another purpose of doing this is to see whether the internal color of the coffee bean is consistent with or close to the outside. The coffee with the same appearance is naturally roasted well and belongs to high-quality beans. If the coffee beans are different from each other inside and outside, it shows that the firepower is too fast or the heat is not well mastered when roasting, and the taste of such beans will be greatly affected when they are finally made into coffee.
