Wine Bottles for a Party
Work out how many bottles of wine and sparkling wine to buy for a party from the guest count and duration, free online.
About this calculator
A 750 ml bottle pours about 5 glasses. Plan roughly one glass per drinker in the first hour and half a glass per hour afterwards. Only some guests drink wine, so the number of wine drinkers is a percentage of the guests; a toast uses one glass of sparkling per guest.
