thus saving energy. Sun tea is sometimes served with syrup or lemon. The temperature of the tea brewed in this manner is never heated high enough to kill any bacteria, leaving the water potentially unsafe to drink. The tea should be discarded if it appears thick, syrupy, or has rope-like strands in it, though it may be hazardous even without such indicators. Because of this danger an alternative called "refrigerator tea" has been suggested where the tea is brewed in the refrigerator overnight. This has the dual advantage of preventing the growth of harmful bacteria and the tea already being cold without the addition of ice. Fountain iced tea In 1996, the City of Cincinnati's Health Department discovered high levels of coliform bacteria (due to inadequate daily cleansing) in the spigots of dispensers filled by automatic fresh brewed iced tea machines in several area restaurants. Approximately the same time, the Coca-Cola and Pepsi Cola companies began aggressive targeted marketing campaigns aimed at replacing fresh brewed iced tea in foodservice establishments with the cola companies' tea concentrate that is dispensed using the same method as fountain drinks, pumped from a bag-in-box. In many cases, the cola companies provided a fountain dispenser for the tea concentrate that looked similar to the containers that were previously used to dispense fresh-brewed tea. Half-and-half There has been a growing popularity in the United States of a mixed drink called "half-and-half" since the late 1960s when golf-great Arnold Palmer ordered one in Palm Beach, Florida. Half-and-half is a mix of iced tea and lemonade, giving the drink a much sweeter taste. Often called an "Arnold Palmer" (although Palmer himself preferred a ratio of two parts iced tea to one part lemonade), the drink was eventually marketed by Snapple, Nantucket Nectars, and AriZona Iced Tea; AriZona has licensed Arnold Palmer's name and image for its versions. In 2012 an ESPN short documentary was produced on the drink, featuring Palmer, beverage experts, a group of PGA golfers and comedian Will Arnett discussing the drink's history and popularity.
