For five thousand years tea was served hot. But when a heat wave hit the World’s Fair in St. Louis in 1904, tea plantation owner Richard Blechynden couldn’t give the steamy stuff away. So he poured it over ice, creating the first iced tea, and the drink became the hit of the fair. Today Nestlé’s drink division, which markets Nestea, produces somewhere in the area of 50 percent of the world’s processed tea. That’s huge business when you consider that tea is second only to water in worldwide consumption.
