Characteristics of Fruit Morphology of Coffee beans A course on the use of coffee machines

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 beans are the freshest and the Aroma taste is the best.

In addition, the purity of coffee beans is also another consideration. The expert candidate for coffee is not necessarily to look at the size of the particles, but to 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. 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 coffee, we should pay attention to its freshness, aroma and whether it is stale or not, and the ideal purchase quantity is to be able to drink it in half a month. The two coffee bean production methods should first remove the skin, pulp, racing peel and silver skin after harvesting the fruit and before shipping it on the market. There are two kinds of methods: drying (also known as natural or non-washing) and washing.
