Cidre Charmat is made using the same process to make Prosecco. The fully matured cider is allowed to sit on the lees or spent yeast until it is ready to be bottled. The cider is then moved to a pressurised container where sugar and yeast is added and allowed to ferment. This gives the cider a lively sparkle. The cider is then put into bottles under pressure and the taste adjusted to Brut, Demi-Sec or Sec and capped.
