This invention relates to improved apparatus for the manufacture of fermented liquors, particularly beer; and it has for its object to provide an improved apparatus of this class which shall be superior from a standpoint of continuity and efficiency of operation, comparative simplicity in construction, compactness in form, and in the obviation of the use of a number of separate apparatuses the use of which is customarily incidental to processes involving the employment of apparatus of this class.
