Abstract: Method and apparatus for clarifying bottled wine by riddling in which the bottles of wine are positioned in generally neck-down inverted position and are subjected to abrupt limited generally vertical force capable of dislodging sediment and solids from adherence to the interior surfaces of the bottles. The apparatus accomplishes the abrupt limited generally vertical force by either lifting and dropping a platform upon which cases of bottles are positioned, or bumping the platform from below. Control means automatically cycles the jouncing action, and supplementary vibratory action, through periods of timed duration and at desired frequencies and amplitudes, the bottles being allowed to remain quiescent for desired periods of time between jouncing actions.
