A method for preventing or removing contaminant build-up in a beer supply line between beer storage means and beer dispensing means, said method including the steps of locating electromagnetic field generating means adjacent a section of said beer supply line, applying a frequency modulated square wave voltage signal to said electromagnetic field generating means to generate a varying frequency electromagnetic field in said section of said supply line, and subjecting said line to said electromagnetic field for an extended period of time to inhibit or remove contaminant cell growth in said beer supply line.
