The base wine is added with yeasts and sugar (tirage),
thus transforming the sugar into carbon dioxide and
alcohol. The wine ageing in the bottle lasts 30
months, producing an elegant, intense perlage; after
that, the phase of dégorgement can start. In order to
bring the Cruperdu to the desired level, the same wine
is used (dosage). Cruperdu then ages 6 months in the
bottle before being released into the market. |
