An assembly for dispensing a beverage from a beverage container includes a cooling chamber containing a pressure chamber configured to accommodate the container and having a lid with a lid opening. The assembly further includes a dispensing tower and a dispensing line channel extending between a lower opening in the cooling chamber and an upper end in the tower. The lid opening is alignable with the lower opening of the channel so that the lid opening provides a guiding element for the passage of a dispensing line between the pressure chamber and the tower through the channel. A method of guiding the dispensing line includes opening the lid of the pressure chamber; aligning the lid opening with the lower opening of the channel; and guiding the dispensing line so that it extends through the lid opening and the channel.
