Disgorgement

Ejecting the frozen plug of lees from a sparkling wine bottle after riddling.

Disgorgement — dégorgement — is the removal of the sediment from a bottle of traditional-method sparkling wine. After riddling has collected the lees in the neck, the neck is frozen, the crown cap removed, and the internal pressure fires the frozen plug out. The bottle is topped up with dosage and corked.

It is the moment a sparkling wine becomes finished and stable — and, importantly, the moment its clock restarts: a wine disgorged last month tastes younger and fresher than the same wine disgorged five years ago, even from the same batch.

In practice

  • À la glace (modern): the neck is dipped in a brine bath at about −25 °C, freezing a plug of wine and lees which shoots out cleanly.
  • À la volée (traditional, now rare): the bottle is opened without freezing and the plug expelled by hand — fast, wasteful, and requiring real skill.
  • A little wine is lost, so bottles are topped up — with dosage, or with the same wine for a zero-dosage bottling.
  • Producers increasingly print the disgorgement date on the back label.

Where you'll meet it

  • Champagne, Crémant, Cava, English sparkling — every traditional-method wine.
  • Recently disgorged (récemment dégorgé, RD) releases: old wines kept on lees and disgorged late, deliberately.

Why the disgorgement date matters

While a sparkling wine sits on its lees, autolysis proceeds slowly and the wine is protected from oxygen. Once disgorged, it begins to age in a normal, oxidative way — quickly at first, as the small oxygen pickup at bottling is absorbed.

Time since disgorgement Character
0–3 months Slightly disjointed; dosage not yet integrated
6 months – 3 years The sweet spot for most non-vintage wines
3–10 years Tertiary development: toast, honey, dried fruit
10 years + For serious vintage wines only; freshness eventually goes

This is why two bottles of the same non-vintage cuvée can taste noticeably different — different disgorgement dates, sometimes years apart.

The transfer method

An alternative for small formats and cheaper wines: bottles are emptied under pressure into a tank, filtered, and re-bottled. No riddling or disgorgement needed. Half-bottles and large formats of otherwise traditional-method wines are often finished this way.
