Riddling
Called rémuage in French, riddling is the process during the making of Champagne or sparkling wine whereby the bottles are individually rotated and tilted a small bit day after day in order to concentrate the yeast sediment in the necks prior to disgorging. In the past bottles held in A-shape frames called pupitres were riddled by hand. Today it may also be done by a computerized machine called a gyropalette.
