Iced black tea is a drink. Iced black tea was invented by accident. 1904 In the summer, Richard Blechynden, a tea merchant, tried to sell his black tea to people when attending the World Expo held in St. Louis, USA, but even Richard couldn't drink his hot black tea because of the unbearable summer heat. Just when he was depressed, a pile of ice cubes accidentally fell into a bucket of hot black tea at hand. Richard thought it would be a pity to lose it, so he took a cup to quench his thirst. Unexpectedly, this cup of iced black tea was cool and carefree, and Richard had a brainwave and resold it. It was sold out. This is the origin of iced black tea.
