An Englishman named Richard Blechynden was unsuccessfully promoting tea at the 1904 World's Fair in St. Louis, Missouri. You see, the sweltering southern heat did little to attract patrons to hot tea, so Mr. Blechynden added ice cubes and the crowdsloved the new brew. Ever since this fortuitous discovery, iced tea has continued to grow in popularity. Tea liqueur is the result of infusing the leaves of the plant Camellia Sinensis in hot water. 80% of the caffeine in tea is released in the first 30 seconds of the infusion. If you want decaffeinated tea, just throw out the liqueur after 30 seconds and brew a second infusion.
