As the United States recognizes its 250th anniversary, there is an Alabama company that has been around for exactly half of the country’s official existence. The Birmingham-based Buffalo Rock Company was founded in 1901, making this the beverage manufacturer’s 125th anniversary. And after a century-plus, the company has not lost any of its fizz.
