Selection method and purchase strategy of high-quality coffee raw beans

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, if crisp sound (indicating that the coffee beans are not wet), teeth cheek fragrance is the top grade, but it is best to pinch with your hand, feel whether solid, rather than buy empty 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 fully release the gas inside the beans.

Generally speaking, the best drinking period of coffee is one week after frying, when the coffee is freshest and the aroma (Aroma) tastes 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. And heavy fire and deep roasting method will cause coffee beans out of oil, but lighter roasted beans if the oil (oily food), it means that it has deteriorated, not only the alcohol degree reduced, but also astringent and sour. In short, when buying coffee, we should pay attention to its freshness, fragrance and old taste. The ideal purchase quantity is to drink it in half a month.
