To manufacture a beverage bottle which is effective and reliable in sterilizing a seamed portion of the hot-filled beverage bottle in a short time, and excellent in economy and sterilizability.
A cap seaming step after a hot-filling step in which the liquid content is hot-filled in the bottle comprises two steps, i.e., a temporary seaming step 2 and a sealed seaming step 5, and a seamed portion sterilizing step. In the temporary seaming step 2, a cap is temporarily seamed so that a clearance is present between the cap and a top side of a bottle mouth so that the liquid content is brought into direct contact with the seamed portion by the overturning sterilization. The seamed portion sterilizing step can employ either or each of the overturning sterilizing step 3 or a pasteurizer sterilizing step 4.
