One hot day in June of 1919 in Lodi, California an entrepreneur named Roy Allen mixed up a batch of creamy root beer and sold the first frosty mug of this delightful beverage for one nickel. Now, more than seventy years later, A&W Root Beer® is the world's number one selling root beer and is still mixed fresh daily and sold at hundreds of A&W® restaurants. Allen purchased the formula for his root beer from a pharmacist in Arizona. To this day, the unique blend of herbs, spices, barks and berries remains a proprietary secret. In 1922 Allen took on a partner, Frank Wright, an employee from his original Lodi location. The two partners combined their initials - "A" for Allen and "W" for Wright and formally named the beverage, A&W Root Beer®. Three units were opened in Sacramento, then on to other northern and central California locations and to the states of Texas and Utah. © A&W Restaurants, Inc.
