                                According to research by Drinkaware, a standard 125ml glass of Prosecco contains roughly 1.5 units of alcohol. Calculating how much Prosecco to have for an event or casual gathering depends on several factors, including the number of guests, the type of occasion, and whether other drinks are being served.
