Mason & Mason, Inc. began bottling root beer in 1947 in Chicago, IL. Mason produced its own root beer concentrate which it soon distributed to over 90 franchisees in 33 states becoming the quintessential root beer taste for a generation of Americans. More than a few were disappointed when Monarch Beverage Company bought it out in the '70s and shelved it in favor of the sweeter flavor of their own Dad's root beer formulation. Fortunately for everyone, it's been brought back off the shelf for you to enjoy!
