The aroma of black coffee

Black coffee emphasizes the aroma of coffee itself. Aroma is not only the life of coffee quality, but also the best expression of coffee production process and roasting technology. The climate of the place of production, variety, refined treatment, harvest, storage, and the appropriateness of baking technology in the consuming country are all conditions that determine the aroma of coffee beans. Bitter is the basic taste of black coffee, there is a difference between strength and texture, raw beans contain only a tiny amount of bitter ingredients, followed by baked sugar, part of starch, fiber caramelization and carbonization, to produce the most symbolic bitterness of coffee.

Black coffee making method

There are three ways to make black coffee: traditional follicle type, siphon type and electric type. The traditional follicle style is the most primitive and simple method of making black coffee. The coffee pot is composed of a funnel, a piece of filter paper and a container below, but it requires high manual craftsmanship. If properly handled, you can make a delicious coffee with a mellow taste. The price of this kind of pot is so cheap that you can buy it for more than ten yuan. The follicular coffee pot is suitable for coffee tasters with stable handle and keen taste. When buying follicular coffee utensils, pay attention to whether it is three holes or one hole, which is very important. The dripping speed of three holes is faster, the extraction time is short, the coffee is lighter, and the opposite is true for one hole. Siphon is based on the principle of siphon. Under the combustion of alcohol, when the water temperature in the lower container reaches 92 ℃, the water is sucked into the upper container with coffee powder. After soaking and stirring, the coffee is returned. Due to the addition of a mixing process, this method of black coffee has a strong flavor, but because it does not need to rely on manual technology, the practice is relatively simple. The market price of this kind of coffee pot is mostly one or two hundred yuan. The price of an electric coffee maker is comparable to that of a siphon coffee maker, which boils the water and soaks it through electricity. It is the easiest way to make black coffee, but it tastes a little worse because it is made from boiling water. In contrast, electric coffee pots are more suitable for young people who are petty bourgeoisie and afraid of trouble. The prices of common electric coffee makers range from one hundred yuan to three or five hundred yuan.

Although the traditional follicle style is the simplest, it is the coffee pot that can best brew the original flavor of coffee. In the process of making black coffee, it is necessary to accurately grasp the water temperature, water flow size and trajectory. A uniform flow and a round track can make the coffee taste natural, so the choice of the kettle and the control of pouring water with both hands are very important. When the water comes into contact with the coffee, it should be kept round as far as possible, from the outside to the inside, from the inside to the outside, so that the coffee is in full contact with the current. At the same time, the water temperature of 92 ℃ can make the coffee fragrant, mellow, sweet, sour, bitter uniform and strong, too high water temperature will scald the coffee, make the taste sour and astringent; low, it is difficult to brew the coffee strong.
