Do you build it? The life of coffee is only ten minutes!

Coffee and movies are old acquaintances. The French Lumiere brothers introduced the film to the public for the first time, in the "Big Caf é" on Gabriel Street. The film is only a few minutes, there is no sound but moving, very much like the coffee in the hands of everyone in the audience.

Yes, the life of coffee, but only 10 minutes. Shake the coffee in your hand and it will form a coffee stain on the wall of the cup within 10 minutes. If the coffee is kept for too long, the fungi that pervade the air will attach to the coffee cup in a very short time, thus contaminating the coffee. This fungus is a pathogenic bacteria, it contains organic can often cause human allergies.

In addition, in terms of taste, coffee contains a substance called tannin, which after extraction will become a yellow powder soluble in water. So if the coffee is not finished in time after brewing, the color of the coffee will become darker and the taste will no longer be so fragrant.

Therefore, it is best to finish the coffee within 10 minutes after brewing, just as the coffee drinkers who witnessed the birth of the first film did. In the winter of more than a hundred years ago, film was born in the history of human civilization, and today, more than a hundred years later, the film predicts that this civilization will end in winter. However, in any case, the day goes on day by day, and instead of complaining about the bitterness of the coffee when it is cold, it is better to feel the brief but warm fragrance of its drink with gratitude.
