A method for producing butter in a buttermaking machine involves using a rotatable beater, in the buttermaking cylinder, to form butter grain and buttermilk with cream supplied to the cylinder. In the drum for the post-buttermaking process, a post-buttermaking process is performed, during which a butter grain size is adjusted. The butter grain is kneaded in the first press, which includes a hollow base body containing one or two screw conveyors, the speed of which can be regulated by a speed-regulated drive, and in addition, the basic water content of the butter is reduced and in the first mixing section, the cross-section of at least one outlet of a throttle device is modified, one or both of the steps and being carried out in an electronically self-regulating manner.
