How to identify good coffee beans and select coffee beans

No matter what kind of coffee beans, freshness is an important factor affecting the quality. When shopping, grab one or two coffee beans and chew them in your mouth. If the coffee beans are crisp and sound, and the tooth pods stay fragrant is the top grade, but it is best to squeeze them with your hands to feel whether they are solid, rather than buying empty-shell coffee. If the coffee bean has lost its fragrance or smells stale, it means that the coffee bean is no longer fresh and is not suitable for purchase. Freshly fried coffee beans are not suitable for immediate consumption and should be stored for a week to completely release the gas in the beans. Generally speaking, the best drinking period for coffee is a week after stir-frying, when the coffee is the freshest and the Aroma is the best. In addition, the purity of coffee beans is also another consideration. When professionals choose coffee, they don't necessarily look at the size of the particles, but grab a handful of individual coffee beans (Regional Coffee), about dozens of portions, to see whether the color of each single bean is the same, and whether the particles are similar in size and shape, so as to avoid buying shoddy products disguised as mixed beans. But if it is a synthetic bean (Blended Coffee), it is a normal phenomenon that the size and color are different. And heavy heat and medium-deep roasting will cause coffee beans to produce oil, but lightly roasted beans, if they produce oil, indicate that they have gone bad, not only reducing aroma, but also astringent and sour taste. In short, when choosing and buying coffee, we should pay attention to its freshness, aroma and stale flavor, and the ideal purchase quantity is to be able to drink it in half a month. "fresh" is the most important factor in buying coffee beans. There are several steps to judge whether the beans are fresh or not: 1. Look: grab a handful of coffee beans and feel whether they are solid beans with the palm of your hand. 2. Smell: whether it is enough to smell the fragrance close to the nose. 3. Pressure: fresh coffee beans are fresh and crisp, and the fragrance floats out when they crack. You can put a bean into your mouth and bite it twice. The crisp sound indicates that the beans are well preserved without dampness. 4. Color: dark black coffee beans, the coffee brewed has a bitter taste; yellow coffee beans, the coffee brewed has a sour taste. Good coffee beans: neat shape, bright color, roasted by single stir-fry, mellow after cooking, full of stamina. Bad coffee beans: different shapes, incomplete individuals, light fragrance after cooking, not sweet enough.

Mainly look at the appearance, if the appearance is black, the taste must be very bitter, because his black element is accumulated too much, so there will be a kind of bitterness, but the effect of drinking this kind of coffee is mainly to treat the annealing, and if the appearance is yellow, it must be moldy, because the coffee beans are moldy inside and breed bacteria, which will make the appearance chemically turn into a yellow shell. But it's okay to eat this moldy coffee, just stay in the hospital for ten or eight days, but if the shell is white, then there must be worms inside to form a white shell.

Select coffee beans

"fresh" is the most important factor in buying coffee beans. There are several steps to judge whether the beans are fresh or not.

one. Grab a handful of coffee beans and feel whether they are solid beans with the palm of your hand.

two. Smell the fragrance close to your nose.

three. Take a bean into the mouth and bite it twice, and there is a clear sound indicating that the bean is well preserved and not damp.

If you want to buy a single product of coffee beans, grab a handful of coffee beans in the palm of your hand, in addition to the above judgment, but also look at the color, grain size and shape of each bean is similar, so as not to buy mixed beans. If you buy mixed beans, it is normal to have different colors, grain sizes and shapes. Some of the beans on the market are bright, some are dull and colorless, this is because some beans have been fried, some have not yet, it is normal for re-baked coffee beans to produce oil, but it is not good for light-roasted beans to produce oil, and the beans may not be fresh at this time! Heavy-roasted coffee beans are full-bodied and will overwhelm the flavor of light-roasted beans, so the best ratio when mixing the two beans is 1 (heavy baking): 3 (light roasting). Of course, this is not the required ratio, you can try several different proportions. If you use Turkish coffee beans or Espresso coffee beans, because the aroma of these two kinds of beans is very rich, you can mix them with some light-roasted coffee beans. The ideal situation is that the freshly fried coffee beans should not be used immediately. They should be stored in sealed cans for about 7 days. After all the fragrance is released, it will be better to grind them. Remember to grind as much as you drink each time, so as to maintain the aroma and freshness of the coffee.
