The color in the body of coffee.

The color of coffee refers to two aspects: the color of coffee beans roasting and the color of coffee soup, that is, the color of coffee liquid. Just like drinking red wine, a cup of coffee to hand, I first need to do neither smell nor taste, but observe the color, first look at the roast color of coffee beans, generally speaking, the lighter the color of coffee beans roast, the closer to wheat color, then the sour taste and unique flavor of coffee will be strengthened, if you are afraid of acid friends can try not to choose this color beans to drink, but in most cases, only higher quality beans will be roasted to a lighter degree, Because if the beans are of poor quality, they have to be dark baked to whitewash their flavor. The darker the coffee beans roast, the closer to black, the more bitter the coffee is and the less flavor it has. It is no exaggeration to say that after roasting to a certain depth, any coffee tastes the same. And the darker the color, the heavier the roasting degree, the more carbonized the coffee beans, and the burnt taste of the coffee will appear. There is no international standard for judging coffee roasting color, but color cards and chromatographs are generally used as a professional quantitative standard. Coffee soup color is almost proportional to coffee roast color in most cases. Generally speaking, the lighter the roast color, the closer the soup color is to amber. The darker the roast color, the closer the soup color is to black. Therefore, the lighter the soup color, the heavier the general sour taste, and vice versa. But what the color reveals is more important is the body of the coffee. Turn the cup slightly to the side and observe the edge of the liquid. According to the fullness of the edge color, you can roughly see whether the alcohol of the beans is very good. The observation of coffee color is the initial cognition of coffee as a whole, so it is very important. A high-quality bean can only truly exert its best flavor if it is roasted to the most appropriate degree. This is also the original intention of observing color.
