The present invention reduces either a production interval or the amount of time it takes until a beverage filling process can be started. In this beverage filling method, in which sterilized containers (4) are filled with a sterilized beverage via beverage-supply-system tubing (7) and said containers are sealed after said beverage-supply-system tubing, through which the beverage is delivered from a heat-sterilization unit (18) to the interior of a filling machine (2), is sterilized, an upstream tubing section (7a), said upstream tubing section (7a) being the part of the beverage-supply-system tubing that passes through the sterilization unit, is provided with an upstream return channel, forming an upstream circulation channel (6a)； and a downstream tubing section (7b), said downstream tubing section (7b) being the part of the beverage-supply-system tubing that extends from the downstream side of the aforementioned upstream tubing section to the interior of the filling machine, is provided with a downstream return channel (6b), forming a downstream circulation channel. The process of filling the abovementioned containers with the abovementioned beverage is started after the following: first, an alkaline cleaning solution is circulated through the upstream circulation channel and the downstream circulation channel to clean and sterilize the inside of the beverage-supply-system tubing； and said beverage-supply-system tubing is then rinsed with sterile water.La présente invention réduit l'un ou l'autre d'un intervalle de production ou de la durée nécessaire avant qu'un processus de remplissage de boisson puisse être démarré. Dans ce procédé de remplissage de boisson, dans lequel des récipients stérilisés (4) sont remplis d'une boisson stérilisée par l'intermédiaire d'une tubulure de système d'alimentation de boisson (7) et lesdits récipients sont scellés après que ladite tubulure d'alimentation de système de boisson, par l'intermédiaire de laquelle la boisson est déliv
