Hand riddled
At this point, the bottles are taken out of the huge niches and, again by hand, placed on racks (pupitres) horizontally, taking care to leave the residue of the lysed yeast cells downwards before starting the long work that will last about 14 days.
From the horizontal position, every day, each bottle is rotated by 1/8 of a turn to dislodge the yeast from the bottle's belly and is slightly lifted to advance the yeast towards the neck of the bottle, until it reaches the vertical position, which will see the yeast collected at the tip. Only at this point will disgorging begin.
