The first step is to smell the fragrance and taste the aroma of coffee;
Step two, look at the color. Coffee should be dark brown, not bottomless.
The third step, tasting, first take a sip of black coffee and feel the taste of original coffee. Coffee should be 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 before swallowing.
Temperature: 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.
Taste: the sugar content of coffee beans is about 5-8%, and most of them are converted into caramel after baking. Caramel is the source of fragrance and bitterness, and the unconverted sugar remains a little sweet; Tannic acid will be released during baking, which will combine with caramel to produce a slightly bitter sweetness. Therefore, people generally have five tastes of coffee: bitter, sour, sweet, fragrant and astringent.
Moderate: Drinking coffee is not like drinking or juice. After watching a full cup of coffee, I lost my interest in drinking. Generally, only seven or eight minutes is appropriate. Moderate coffee will not only stimulate the taste, but also will not feel greasy after drinking, but will have an endless aftertaste. At the same time, the right amount of coffee can moderately promote the recovery of fatigue and refresh the mind. There are shades of coffee, so you can't drink several cups in a row like tea and cola. Regular coffee is 80- 100cc, sometimes if you want.
