Whole grapes are put into the pneumatic press for soft pressing and the resulting must, after a first racking, is put into controlled temperature tanks where it remains until it is used for the production of the sparkling wine. The must with added yeast cultures selected by Villa Sandi is then put into vessels where fermentation takes place at a controlled temperature of 15-16ËšC to enhance all the harvest fragrances. Upon reaching the required alcohol and sugar content fermentation is stopped by refrigeration. After a short settling period, the sparkling wine is ready for bottling.
