The wines selected in this way (referred to as ‘base wines') are then carefully blended by our cellar-masters to ensure Kriter maintains a constant taste and quality. A liqueur de tirage (comprising sugars, yeast, and wine) is then introduced into the vat, which starts the second fermentation that is going to create the bubbles. For long months, the wine will be aged on its lees, as time goes by developing its aromas and fine, light bubbles.
