Drinking coffee notes

Less 3-in-1 coffee. From the cost considerations, a cup of coffee of 5 yuan, 10 yuan, usually do not use better quality coffee beans. As for the three-in-one coffee, most of them are made from coffee extract or coffee flavoring powder, and it's impossible to use good coffee beans, and the sugar and creamer added inside are higher in calories.

Smell and taste with your tongue. When you drink coffee, don't swallow it whole, but smell it close to your nose first, and if you smell it with a halo odor, it means the coffee beans are not fresh. After passing the smell test, take a mouthful of coffee in your mouth, taste it with your tongue, and slowly swallow it down your throat. If you drink clean and bright, full of pleasant aroma, and no adverse body reaction, is a good cup of coffee.

Replace creamer with fresh milk. For the sake of health, it is recommended to use fresh milk instead of creamer and add less sugar so as not to negate the original benefits of coffee.
