disgorging

wine making
Also known as: dégorgement

Quick Summary

Disgorging is a crucial step in the production of sparkling wines, particularly those made using the traditional bottle fermentation method, also known as méthode champenoise. This process involves removing the yeast sediment that accumulates in the neck of the bottle after the secondary fermentation.

The Disgorging Process

  1. Riddling: Bottles are gradually turned and tipped until the sediment collects on the cork.
  2. Freezing: The neck of the bottle is frozen to solidify the sediment.
  3. Disgorging: The cork is removed, and the internal pressure ejects the frozen sediment. This is the disgorging step.
  4. Refilling and Recorking: A small amount of sweetening dosage is added, and the bottle is quickly recorked and secured with a wire cage.

This technique ensures a clear, sediment-free sparkling wine with a refined flavor profile developed during aging.12
