sediment (" lees") left in the bottle after the fermentation, ''riddling'' (or in French ''remuage'') is performed. At certain intervals, the bottle is twisted, shaken slightly and moved progressively to a vertical position with the neck pointing down. Traditionally, this used to take place manually over the course of several weeks, with wine cellar workers called ''remueurs'' performing the task on each individual bottle, on wooden racks. A Gyropalette performs the same task automatically on many bottles at the same time, and in a shorter period of time. The bottles are placed in a cage, and are moved in a way which emulates the action of a remueur by means of motors and automatic controls. The Gyropalette was invented by two French vintners, Claude Cazals and Jacques Ducoin, who filed for
