Filbert's Diet Cola is a classic diet cola from Chicago. Known best for its namesake root beer, Filbert’s also produces 17 flavors of soda such as diet cola. The company started at the turn of the century when George Filbert and family delivered milk, ice and coal to homes in the Bridgeport neighborhood by horse-drawn wagon. The family added root beer when it became popular during Prohibition. It was manufactured in half barrels and supplied mostly to taverns across five nearby states.
