The Independent Breweries Company was a syndicate founded in St. Louis, Missouri, by the combination of Griesediecks' National Brewery, Columbia (Alpen Brau), the Gast brewery in Baden, A.B.C., and Wagner Brewing Company.
 This combination was ill fated due to high overhead with too many executives and low profits forcing IBC into receivership.
 The IBC Root Beer was the main survivor of the syndicate.

Root beer is a sweet North American soft drink traditionally made using the sassafras tree "Sassafras albidum" (sassafras) or the vine "Smilax ornata" (sarsaparilla) as the primary flavor.
 Root beer may be alcoholic or non-alcoholic, come naturally free of caffeine or have caffeine added, and carbonated or non-carbonated.
 It usually has a thick, foamy head when poured.
 Modern, commercially produced root beer is generally sweet, foamy, carbonated, nonalcoholic, and flavoured using artificial sassafras flavouring.
 Sassafras root is still used to flavor traditional root beer, but since sassafras was banned by the U.S. Food and Drug Administration due to the controversially claimed carcinogenicity of its constituent safrole, most commercial recipes do not contain sassafras.
 Some commercial root beers do use a safrole-free sassafras extract.

 The company name was taken respectively from the initials of their last names—Allen and Wright.
 The company became famous in the United States for its "frosty mugs," where the mugs would be kept in the freezer and eventually get filled with A&W Root Beer before they are served to customers.
