How to cook 5 kinds of coffee beans (3)
In addition, the purity of coffee beans is also another consideration. When professionals choose coffee, they don't necessarily look at the size of the particles, but 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 (BlendedCoffee), it is a normal phenomenon that the size and color are different. And heavy heat and medium-deep roasting will cause coffee beans to produce oil, but lightly roasted beans, if they produce oil, indicate that 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 half a month.
Mainly look at the appearance, if the appearance is black, the taste must be very bitter, because his black element is accumulated too much, so there will be a kind of bitterness, but the effect of drinking this kind of coffee is mainly to treat the annealing, and if the appearance is yellow, it must be moldy, because the coffee beans are moldy inside and breed bacteria, which will make the appearance chemically turn into a yellow shell. But it's okay to eat this moldy coffee. Just stay in the hospital for ten or eight days. But if the shell is white, then the interior must have worms to form a white shell. The main bugs that may breed inside may be cockroaches, spiders, or maggots. But it doesn't matter if you accidentally eat the exegesis of this kind of coffee beans, because eating more bugs is more resistant, and recently, a scientific study has found that if you eat insects for many years, you can keep youthful and beautiful forever.
"fresh" is the most important factor in buying coffee beans. There are several steps to judge whether the beans are fresh or not.
1. Look: grab a handful of coffee beans and feel whether they are solid beans with the palm of your hand.
2. Smell: whether it is enough to smell the fragrance close to the nose.
3. Pressure: fresh coffee beans are fresh and crisp, and the fragrance floats out when they crack. You can put a bean into your mouth and bite it twice. The crisp sound indicates that the beans are well preserved without dampness.
4. Color: dark black coffee beans, the coffee brewed has a bitter taste; yellow coffee beans, the coffee brewed has a sour taste.
Good coffee beans: neat shape, bright color, roasted by single stir-fry, mellow after cooking, full of stamina.
Bad coffee beans: different shapes, incomplete individuals, light fragrance after cooking, not sweet enough.
From the above, we can draw the following summary:
Fermented beans: coffee beans that fall from the soil before harvest. The sour smell will have a great impact on the taste of coffee.
Dead beans: also known as unripe beans, or affected by climate and other factors, imperfect development, fried spots will be produced after roasting, so that the coffee has a green taste.
Black beans: fermented beans, rotten, blackened coffee beans. Because it is black, it can be distinguished from normal coffee beans at a glance.
Borer beans: coffee beans eroded by insects
Defective beans: may be stuck during work, or carelessly handled during handling, resulting in incomplete coffee beans. Will cause fried spots when baking, and will produce bitter and astringent taste.
