The Perplexity of Literary Youth: how to choose Coffee beans?

Friends who like coffee will not be careless in their choice of coffee beans. Learning to choose coffee beans is the first and most important step. 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.

When buying coffee, it is better to buy coffee beans rather than ground coffee powder. although they are all the same in essence, the actual situation is that the ground coffee powder is very easy to oxidize and not easy to preserve. Even those coffee powders that seem to last for a long time, in fact, add a lot of preservatives, which will greatly affect the taste of later brewed coffee, so, if you want to make a good cup of coffee, the best and right thing to do is to grind the coffee on the spot before brewing it, so as to maintain the mellow and taste of the coffee to the maximum extent. The average coffee bean can be preserved for about a month, but if it is coffee powder, it should not be more than five days at most.

Today, let's take a look at the magic skill of the god's coffee bean selection:

The first point:

It is necessary 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 indicate that coffee beans are best sealed in dark boxes or jars.

The second point:

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 know the basics by heart. Coffee beans will show different colors depending on the degree of roasting. 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. Detailed list is the following eight levels, from shallow to deep: shallow baking, meat baking, moderate baking, deep baking, urban baking, full-process baking, French baking, Italian baking, of 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 still the same. And coffee beans also 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 pollution-free.

The fourth point:

That 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 fragrance of coffee, while coffee beans that are not fresh or have been over-oxidized will have a poor or basically no flavor, and serious coffee beans will have a musty smell. The smell of earthy and iodine may even have the taste of fermentation.

Fifth point:

It is also the most essential point, press or taste it directly with your hand, because when you squeeze the coffee bean with your hand, the good coffee bean will not only give off the overflowing fragrance but also accompany the crisp crack sound when it cracks. further, you can put the coffee bean into your mouth and bite it open. If the sound of the crack is crisp and short, then it shows that the coffee bean is not wet. Another purpose of doing this is to see whether the internal color of the coffee beans 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.
