Never Drink Yesterday's Tea

Tea connoisseurs and producers recommend drinking this beverage freshly brewed. It's not just about the better expression of the tea's taste and aroma. If the drink is left in open air for several hours, oxygen causes bacteria and harmful compounds to form. On the surface of the tea, they appear as a dense dark film, leaving a residue on the cup. These substances have the most destructive effect on the digestive organs, primarily the liver. Tea left for a day is deemed 'worse than a snakebite' by the Japanese, and the Chinese compare it to poison.
