Tea has been around forever, but iced tea didn’t burst onto the scene and win over America’s hearts and minds until 1904. In that year, visitors to the St. Louis World’s Fair were greeted by exceedingly hot weather. Tea plantation owner and merchant Richard Blechynden, who was present at the fair, took advantage of the situation by selling chilled tea drinks (instead of hot tea) as a cold refreshment. The rest is history. On June 10, we fill our glasses with iced tea (sweetened or unsweetened—that’s your call) and celebrate National Iced Tea Day.
