There are several kinds of coffee beans on the island of Sumatra in Mantenin, Indonesia.

Choose fresh coffee beans. Pay attention to whether the color and particle size of the beans are consistent when purchasing. Good coffee beans have a bright and shiny appearance, and have a strong aroma without mixing odors. No matter what kind of coffee beans, freshness is an important factor affecting quality. When purchasing, grab one or two coffee beans in the mouth to chew, to crisp sound (indicating that the coffee is not wet), teeth cheek fragrance is the top grade, but it is best to pinch with your hand, feel whether solid, rather than buy crispy shell coffee. If the coffee beans have lost their aroma or smell old, it means that the coffee beans are no longer fresh and are not suitable for purchase.

Freshly fried coffee beans are not suitable for immediate drinking and should be stored for a week in order to completely release the gases in the beans.

Generally speaking, the best drinking period of coffee is one week after frying, when the coffee beans are the freshest and the aroma (Aroma) tastes the best.

In addition, the purity of coffee beans is also another consideration factor, experts choose coffee, not necessarily to see the size of the particles, but to grab a handful of single coffee beans (Regional Coffee), about dozens of weight, to see whether the color of each single bean is consistent, particle size, shape is similar, so as not to buy mixed beans disguised as inferior products. But if it is a comprehensive bean (Blended Coffee), the size, color difference is a normal phenomenon. In addition, heavy fire and medium and deep roasting method will cause coffee beans to be oily, but if the beans are lightly roasted, it means that they have deteriorated, not only the degree of fragrance is reduced, but also astringent and sour. In short, when buying coffee, you should pay attention to its freshness, aroma and whether it has an old taste, and the ideal purchase quantity is to drink it in half a month.
