Sparkling wine made by the traditional method acquires its bubbles from

  • A.A second fermentation taking place inside the bottle
  • B.Carbon dioxide gas injected under pressure before sale
  • C.The first fermentation being stopped before it finishes
  • D.Malolactic fermentation carried out in the vat

Answer: A

Correct answer: A second fermentation taking place inside the bottle

In the traditional method a still base wine is bottled with sugar and yeast, and the carbon dioxide from the resulting fermentation dissolves under pressure because it cannot escape. The wine then rests on the spent yeast, which contributes the characteristic biscuit and bread notes, before the deposit is riddled into the neck and disgorged.
