Recipes for iced tea have been found dating back to the 1870s. The Buckeye Cookbook, published in 1876, and Housekeeping in Old Virginia, published in 1877, both contain iced tea recipes. It is believed, however, that iced tea started to appear in the United States in the 1860s and became widespread in the 1870s.
10 June each year is celebrated as the National Iced Tea Day. Iced Tea is one of summer's favourite drinks!
