Four aspects that should be paid attention to in selecting coffee beans
When buying coffee, you 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. Here are four aspects to pay attention to when choosing coffee beans:
1. When buying, pay attention to whether the color of the beans and the size of the particles are the same. Good coffee beans are shiny and have a strong aroma without being mixed with peculiar smell. No matter what kind of coffee beans, freshness is an important factor affecting the quality.
two。 When shopping, grab one or two coffee beans in your mouth and chew them with a crisp sound (indicating that the coffee is not damp) and the fragrance of the teeth and cheeks is the top grade, but it is best to squeeze it with your hands to feel whether it is solid, rather than buying crispy 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.
3. 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.
4. 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.
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.
