How do you choose coffee beans directly?

No matter what kind of coffee beans, freshness is an important factor affecting the quality. When choosing and buying, grab one or two coffee beans and chew them in your mouth. If the coffee beans are crisp and sound, and the teeth and cheeks stay fragrant, it is the top grade, but it is best to pinch them with your hands and crush them to see if they are solid, rather than buying empty-shell coffee. If the coffee beans have lost their fragrance or smell stale, it means that the coffee beans are no longer fresh and 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 from 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 (appearance) of coffee beans is also another consideration. The expert candidate for coffee is not necessarily looking at the size of the particles, but grabbing 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 Blended Coffee, it is normal to have different size and color. In addition, heavy heat and medium-deep roasting will cause coffee beans to produce oil, but if the lightly roasted beans produce oil, they have gone bad, not only reducing aroma, but also astringent and sour taste. In short, when buying added 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 one month.
