The invention discloses a method of controlling operation of a beveragedispenser,comprising the following steps:- selecting a water recipe from a plurality of water recipes, whereineachwater recipe defines a set concentration of minerals to be solved in thewater and wherein the water is mineralized based on the water recipe byadding minerals by a mineralization device；- verifying, whether the user is allowed to adjust a user adjustable aproperty of the water to be mineralized by the mineralization deviceaccording to water recipe, wherein the user adjustable property comprisesat least one of a set temperature of the water to be mineralized and a setcarbonization of the water to be mineralized；- preparing the water by at least one water preparation elementaccording to the user adjustable property； and- outputting the mineralized water to a user vessel；further comprising at least one of the following steps:- activating on a display a temperature user interface element foradapting the temperature of the water to be mineralized in a predeterminedtemperature range, if the user is allowed to adapt the set temperaturewithin the predetermined temperature range； and- activating on the display a carbonization user interface element foradapting the set carbonization of the water to be mineralized in apredetermined CO2 concentration range, if the user is allowed to adapt theset carbonization within the predetermined CO2 concentration range.
