Abstract: A method and apparatus for the removal of foam produced in the primary fermentation step of home brewmaking comprises primarily a kraeusen trap including a platform of a diameter slightly less than the inside diameter of a primary fermenter and one or more chimneys to permit the flow of foam from below the platform to the top surface of the platform. The device may also include means for maintaining a space between the perimeter of the platform and the inside surface of the primary fermenter. This space permits foam to flow around the platform to the top surface of the platform, and for beer brought with the foam to settle back into the batch. Each of the one or more chimneys may also include one or more drain holes for the flow of beer into the batch. The space between the platform and the inside diameter of the primary fermented is preferably maintained by a plurality of spacers, which preferably clip onto the perimeter of the platform.
