The invention relates to a production method of beer with
high alcohol content, and belongs to the technical field of beer production. According to the method, beer is frozen into a
solid state (hereinafter referred to as an ice body), a heat source is arranged in a specific direction to transfer heat to the beer ice body, and the
alcohol content of the beer is improved through temperature-controlled
dissolution. The specific orientation of the heat source is set to be a directional area. For example, when the beer is frozen into an ice body (a
freezing chamber or a container) from the cooling surface, the specific orientation is an orientation which is vertically separated from the cooling surface towards the ice body (from the cooling surface). After the beer is frozen into an ice body, according to the solute content of the ice body, the specific orientation is the orientation where the solute content of the ice body is high. The beer is frozen into an ice body, and the
alcohol content of the beer is gradually reduced in a temperature-controlled
dissolution process by arranging a heat source in a specific direction. And according to the requirement of the target
alcohol content, the solution is retained in sections, so that the beer with different alcohol contents is obtained. And transferring the beer conforming to the target
alcohol content to the next link for storage (utilization). For beer which does not meet the target
alcohol content, the
alcohol content of the beer can be continuously improved through the method (repeated freezing, dissolving and segmented taking). The method is simple to operate, high in efficiency and capable of being operated at normal pressure and low temperature, substances which are beneficial to health and sensitive to
heat sensitivity in the beer are reserved, and the alcohol content, the taste and the fragrance of the beer are greatly improved.
