Villa Sandi pride themselves on gorwing some of the best Glera grapes used for Prosecco - they are picked by a combination of machine and hand depending on the vineyard, and the grapes taken to their state of the art winery where the grapes are pressed, and the juice transferred into tanks for the first fermentation in steel temperature controlled conditions. The first ferment produces a naturally fruity yet crisp light wine, which is then transferred under pressure into a second tank where the wine is inocculated with yeast and sugar to start a secondary alcoholic fermentation - after which the now sparkling yet cloudy wine is transferred under pressure into a third tank for filtering and clarification, before transfer to another holding area ready for batch bottling. This is the unique 'Charmat,' or Tank method - where the wine is transferred through a series of stages, each designed to produce a top quality sparkling wine.
