Abstract: A riddling machine for making champagne is proposed, with a base, main motor, main shaft driven by the motor, pivotal parallel frames each fixed to a first half-axle and a second hollow half-axle revolvably mounted, and an inner shaft enclosed into the second half-axle, bevel gears including a driving wheel coupled to the inner shaft, and a driven wheel rotatably mounted on the frame furnished with bottle holders and controllably rotatable within an ALPHA angle range and capable of revolving the holders, a first gear capable of conveying rotation from the main shaft to the inner shafts, an intermediate shaft controllably engaged/disengaged with the main shaft, and connected through a braking muff to an intermediate axle, and a second gear capable of providing a controllable tilt angle BETA of the frames driven via the intermediate axle, and conveying rotation to the first half-axles of frames.
