Before removing sediment from Champagne, why are the bottles slowly turned upside down over weeks?
Show answer & explanation
Answer: Sediment slides to neck
Tighter sediment clump — A tighter clump would be useful only after the sediment reaches the right place. If the deposit stayed along the side or bottom of the bottle, compacting it would not make it easy to eject. Riddling's main job is positional: guide the sediment into the neck so the next step can remove it cleanly.
Sediment slides to neck ✓ — Right: riddling gradually loosens and guides the lees down into the bottle neck. The old hand method can take 4-6 weeks and around 25 turns per bottle, though machines now do it faster. It is a wonderfully physical solution: use gravity and tiny rotations to make a cloudy bottle ready for a clear pour.
Cork pulls sediment — The cork sits at the end of the process, so it is tempting to imagine it attracting the sediment. But riddling relies on gravity, tilt, and tiny rotations, not a sticky stopper. The deposit has to be collected in the neck before disgorgement; otherwise the bottle would be much harder to clear without clouding the wine.
