fragrance

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.

raw material

Coffee beans are the raw material of black coffee. There are hundreds of kinds of coffee beans, and the price varies according to the variety, origin and grade. We are familiar with Yunnan coffee, Blue Mountain, Mantening, Huju, Brazil and charcoal, which can be bought in many supermarkets, and most of them are baked beans.

Due to different producing areas, the characteristics of coffee beans are different, some of which are darker in color, higher in baking degree and stronger in taste; Some are lighter in color and slightly lighter in taste. Experts choose coffee, mostly by grabbing a handful of coffee beans to see whether the color of each bean is consistent and whether the particle size and shape are similar, so as to avoid buying inferior products disguised as mixed beans. In addition, if the baked beans are oily, it means that they have gone bad, not only the mellow degree is reduced, but also the astringency and sour taste will appear.

The amount of coffee to drink should be controlled.

Although coffee can promote fat metabolism and help to lose weight and burn fat, in fact, the amount of coffee you drink every day should not exceed 10 cup, calculated according to each cup 150ml. Drinking too much coffee will make the nerve center too excited, causing insomnia, anxiety and irritability, while too much alkaline substances will also affect gastric acid secretion, leading to gastrointestinal obstruction, and even gastric mucosal damage and gastric ulcer. Therefore, never drink too much coffee. Generally speaking, 2-3 cups a day can meet the needs of a day. Never drink too much coffee.

Drinking coffee can help you lose weight, but you should also find the right time to give full play to the effect of coffee. Expert research shows that when you finish drinking coffee for 40 minutes, the concentration of fatty acids in your blood will rise to the highest, which is the best time to lose weight by exercise, because fatty acids will promote the decomposition of fat and make exercise slimming more effective. Therefore, the time to drink coffee can be placed half an hour before exercise, and the slimming effect will be greatly improved.

Find the right way to drink coffee

Baking method is very important.

The flavor of coffee is mainly determined by the roasting time and temperature of coffee beans, which also determine the caffeine content in the final coffee. Generally speaking, the temperature of roasting coffee beans is 178 degrees, because this temperature can make the flavor of coffee beans completely give off, but it is also the temperature at which coffee decomposes. Therefore, although the flavor of deep roasted coffee is very good, the coffee content is actually very low, so if you want to lose weight, you should choose shallow roasted black coffee.

There is a difference between cold drinks and hot drinks.

With the development of coffee making technology, from espresso to carbonated drinks, ice cream and milk, and then to ice-cold coffee to adjust the taste, these composite versions of coffee are favored by many young girls. But in fact, the effect of coffee can only be best when drinking hot coffee, so you will feel hot after drinking hot coffee for half an hour, which is the result of coffee promoting blood circulation. In contrast, the efficacy of iced coffee is much weaker, even less than one-third of that of hot coffee.

Etiquette and steps of drinking coffee

1. Take a sip of ice water before you start drinking coffee. Ice water can help the taste of coffee emerge clearly, so that every taste bud on your tongue is fully prepared to feel the delicious taste of coffee, and it can also clean your mouth.

When a cup of coffee is served to you, don't drink it first. Just like tea or wine tasting, there must be a gradual process to achieve the purpose of relaxation, refreshing and enjoyment. Smell the aroma first and taste the aroma of coffee; Look at the color again and feel the visual impression of coffee.

3, tasting, first take a sip of black coffee and feel the taste of original coffee. The coffee entrance should be a little sweet, slightly bitter and slightly sour. Then sip coffee. Don't swallow coffee in one gulp. Put it in your mouth for a while, let the coffee and saliva mix with the air a little, and then swallow it. Don't forget to have a sip of black coffee. Every cup of coffee you drink must go through five years of growth, complicated procedures such as harvesting and baking, and careful preparation by the barista before it can blossom and bear fruit. So, first take a sip of "black coffee" without sugar and creamer while it is hot, and feel the taste of coffee before it is pulverized. Then add some sugar, take another sip, and finally add cream. In this way, the taste of coffee is on the tip of the tongue.

4. Drink coffee while it is hot. Because the tannic acid in coffee is easy to change during the cooling process, it makes the taste sour and affects the flavor of coffee. The best temperature for drinking coffee is 85-88 degrees Celsius. Because the texture of ordinary coffee is not stable, it is best to taste it while it is hot. In order not to reduce the taste of coffee, you should soak the coffee cup in boiling water in advance. The suitable temperature of coffee is 83℃ at the moment of brewing, 80℃ in the cup and 6 1-62℃ at the entrance, which is the most ideal. Generally speaking, drinking coffee while it is hot is also a basic etiquette. If it is a cup of good quality coffee, the taste performance is the same as that when it is hot, or even better, but the aroma will be reduced after cooling.

5, drink the right amount of coffee contains coffee, so drink it in moderation. Don't fill a cup of coffee. If you look at a full cup of coffee, you will lose interest in drinking. Generally, only seven or eight minutes is the right amount, and the right amount of coffee can moderately promote the recovery of fatigue and refresh the mind. Ordinary coffee consumption is 80- 100cc. Sometimes if you want to drink three or four cups in a row, you have to dilute the concentration of coffee or add a lot of milk, otherwise it will cause a disgusting feeling. You might as well make more changes in the distribution of sugar to make coffee more delicious.

How to add sugar and cream

Except only black coffee (no sugar and cream). When adding sugar, if you add sugar cubes, you should add them in the following order: first put the sugar cubes on the spoon, and then gently put the spoon into the cup. Only in this way can we avoid coffee overflowing the cup when adding sugar cubes. Cream can be added directly. Similarly, in order to avoid coffee spillage, the position should be as low as possible.

The use of coffee cups and saucers

Coffee after a meal is usually served in a small cup. The ears of this cup are so small that fingers can't pass through them. But even if you use a bigger cup, you don't need to put your finger through the ear of the cup before holding it. The cups and saucers for holding coffee are also specially made. You should put them in front of you or on the right, with the ear pointing to the left.

The correct way to hold a coffee cup is to hold the cup handle with your thumb and forefinger and lift it up. When drinking coffee, hold the coffee cup ear with your right hand, gently hold the coffee tray with your left hand, and slowly sip it to your mouth to avoid making noise. It is not advisable to hold up a cup and swallow it, or lower your head to suck coffee. Sometimes you will encounter some inconvenient situations, for example, it is inconvenient to sit on the sofa far from the table and drink coffee with both hands. At this time, you can put the coffee dish on your chest with your left hand and drink the coffee cup with your right hand. After drinking, the coffee cup should be put into the coffee tray immediately, and the two should not be placed separately.

Etiquette for drinking coffee

1. Don't add sugar or cream to other people's coffee without authorization. If you are a guest in someone else's house, don't pour coffee for yourself or others without authorization, because it is the obligation and right of the host.

The newly brewed coffee is too hot. You can gently stir the coffee spoon in the cup to let it cool, or you can wait for it to cool naturally before drinking. It is very impolite to try to blow cold coffee through your mouth.

3. Coffee spoon is used to stir coffee. Stir gently. Don't make coffee cups jingle, and don't drink coffee with a coffee spoon. This is also impolite. Sometimes you can have some snacks when drinking coffee, but don't take a coffee cup in one hand and a snack in the other, take a sip and drink alternately. Put down the snacks when drinking coffee, and put down the coffee cup when eating snacks.
