Alcohol stabilizer for offset printing dampening solution, with a metering float for metering of alcohol into the dampening solution from a supply. An emergency cut-off float interrupts the supply of alcohol by ventilating the alcohol supply path when the alcohol content in the dampening solution reaches or exceeds an emergency cut-off value. The metered flow of alcohol is introduced into a recirculation path from and then back to a main vessel of the dampening solution.
