Royal Palm root beer was great
Hires is too.
Barq's is ok.
Hires Root Beer, America's original root beer, is more than 120 years old and the oldest continuously marketed soft drink in the United States. Created by pharmacist Charles E. Hires, it began as a delicious herbal tea made of roots, berries, and herbs. After perfecting the recipe in his drugstore, Hires decided to call his drink "root beer" because a friend thought it would be more appealing than "herbal tea."
Hires Root Beer debuted at the 1876 U.S. Centennial Exposition in Philadelphia, along with Alexander Graham Bell's telephone, the Remington typewriter and Heinz Ketchup. To stand out in such company, Hires touted Hires Root Beer as "The Temperance Drink" and "the Greatest Health-Giving Beverage in the World." Hires aggressively advertised his product, believing that "doing business without advertising is like winking at a girl in the dark. You know what you are doing, but nobody else does."
Hires Root Beer quickly became a sensation. By the early 1900s, many homes in America had Hires Root Beer Kits, mixing a dry extract with water, sugar and yeast to produce the product for five cents a gallon. The kits were available to consumers until the 1980s.
Charles Hires stubbornly insisted on using better ingredients and flavorings than his competitors. This frustrated his accountants, but Hires Root Beer ultimately became synonymous with high quality, a Hires trait appreciated by today's loyal consumers.
