From a site devoted to collecting old bottles:

1876 Louis Giering established the Giering Bottling business, his plant being located in the country at what is now Edwards Street, Youngstown Ohio. This business is therefore one of the oldest of its kind in Eastern Ohio. J.F. Giering, son of the founder became the active manager in 1896. This company are/were the manufacturers and distributors of Coca-Cola; for the Youngstown district, Youngstown, Ohio.

Either that's wrong, or they played both sides of the fence.
