According to the inventive method, the filling of a drinks container (10) with a drink (15) produced from an initial liquid (24) and containing a gas dissolved therein is carried out in an inventive device (20) comprising a filling device (50) which fills the drink container (10) with the drink (15)
According to the inventive method, the filling of a drinks container (10) with a drink (15) produced from an initial liquid (24) and containing a gas dissolved therein is carried out in an inventive device (20) comprising a filling device (50) which fills the drink container (10) with the drink (15) in such a way that a pre-determined residual gas volume (14) remains above the drink (15) in the drinks container (10). The inventive device also comprises a closing device (74) which closes the drinks container (10). According to the invention, a liquid oxygen supply device (64), which is directly arranged upstream of the closing device (74) in the transport direction of the drinks container (10), introduces a pre-determined amount of liquid oxygen into the drinks container (10). The inventive drinks container can hold even high concentration of gas, especially oxygen, dissolved in the drink at least until the best before date.
