From Delta Airlines’Sky magazine of May 2018:

• Approximately 92,000 pounds of tea were destroyed during the Boston Tea Party, the present-day value of which has been estimated to be around $1 million.
• Herbal teas aren’t actually teas but tisanes: infusions of seeds, berries, flowers, leaves and/or roots.
• When his hot tea didn’t sell at the 1904 World’s Fair in St. Louis, merchant Richard Blechynden offered iced tea and became known for popularizing the drink.
