Vinification
The vinification takes place in steel at a controlled temperature. In January, the liqueur de tirage necessary for frothing is added to the base wine. The wines are then bottled and capped with a crown cap.
Refinement
At the end of fermentation, a process that lasts about fifty days, and at the end of the subsequent frothing, the wines remain sur-lie in the bottle.
