Tea is the most consumed beverage, after water, in the world. Here in the U.S., however, coffee rules. That may change. On any given day, about half of the American population drinks a cup of tea, according to the Tea Association of the USA, with the greatest concentration of tea drinkers in the South and Northeast. They like it cool, too; 85 percent of tea consumed is iced and much of that is RTD (ready to drink). Of the hot stuff, 65 percent is brewed from bags, but loose tea is gaining popularity.
