A method is provided for filling a bag with an alcohol beverage inflates the bag with an inert gas prior to filing the bag with the beverage. The inert gas is vented from the bag as the bag is filled with the beverage. By initially inflating the bag with the inert gas, the bag is not inflated during the step of filling the bag with the beverage and hence, the bag is less susceptible to rupture during beverage filling the inert gas acts to purge any air trapped in the bag. During the venting step the inert gas and air mixture is vented from the bag. There is less chance for air to be trapped in the bag and spoil the beverage in the bag. In a further aspect, the bag is contained in a container and the air between the container and the bag is also evacuated. The inert gas may be CO₂ or nitrogen when the beverage is beer. Also provided is a valve and valve and spear assembly for alcohol dispensing apparatus.
