Black coffee is coffee without any modification. Black coffee brings the original feeling of tasting coffee. Black coffee combines the five flavors of coffee, sweet, sweet and bitter. It is primitive, rough, profound and intriguing.
Black coffee emphasizes the aroma of coffee itself. Aroma is the life of coffee quality, which can best express the making process and baking technology of coffee. The climate, variety, refining treatment, harvesting, storage and baking technology of the consuming country are all conditions that determine the aroma of coffee beans. Bitterness is the basic taste of black coffee, and its strength and texture are different. Raw beans only contain a very small amount of bitter ingredients, and then the most symbolic bitter taste of coffee is produced by caramelization and carbonization of sugar, starch and fiber caused by baking. Black coffee also has a sour taste. Proper heating will produce moderate acidity, which will make coffee taste better and make people feel deeper. The sweetness of black coffee is closely related to the bitterness, so refreshing and superior black coffee tastes sweet.
There are three ways to make black coffee, so there are three different types of coffee pots: traditional filter, siphon and electric. Traditional filters are the most primitive and simple tools. Coffee pot consists of a funnel, a filter paper and a container below, but it needs a high degree of manual technology. If you grasp it properly, you can cook the best coffee with mellow taste. This kind of pot is very cheap, you can buy it for more than ten yuan. The brewed coffee pot is suitable for people who drink coffee, with stable hand feel and sharp taste. Siphon type uses the siphon principle. Under the burning of alcohol, when the water temperature of the lower container reaches 92 degrees Celsius, the water flow is sucked into the upper container together with the coffee powder. After soaking and stirring, the coffee returns to its original way. Due to the addition of a stirring process, this method of black coffee has a strong flavor, but it is relatively simple because it does not require manual skills. The market price of this coffee pot is mostly one or two hundred yuan. The price of electric coffee pot is comparable to that of siphon coffee pot. It uses electricity to boil water and then soaks it. This is the easiest way to make black coffee, but because it is made with boiling water, it tastes slightly inferior. Comparatively speaking, the electric coffee pot is more suitable for young people with petty bourgeoisie who are afraid of trouble. The price of common electric coffee pots ranges from one hundred yuan to three or five hundred yuan. Although the traditional filter type is the simplest, it is the coffee pot that can best cook the original flavor of coffee; In the production process, it is necessary to accurately grasp the water temperature, water flow size and trajectory. Uniform water flow and circular trajectory can make coffee taste natural, so it is very important to choose and control the kettle when pouring water with both hands. When the water comes into contact with coffee, it should be as round as possible, from outside to inside and from inside to outside, so that coffee can fully contact with the water; At the same time, the water temperature of 92 degrees Celsius can make the aroma, alcoholicity, sweetness, acidity and bitterness of coffee uniform and strong. If the water temperature is too high, it will burn the coffee and make the taste sour and astringent. On the low side, it is difficult to brew the aroma of coffee.
