Reference table assumes everyone drinks, 750 ml bottles and no spare; round up and add a bottle or two to be safe.
A standard 750 ml bottle pours about 5 glasses at 150 ml (5 oz), 6 glasses at 125 ml, or about 8 small toast pours of 90 ml (3 oz).
For a single toast with 90 ml pours, one bottle serves about 8 people, so 50 guests need 6 bottles. Add one spare bottle for spills and refills.
If drinkers have about 2 full glasses each plus the midnight toast, plan roughly one 750 ml bottle for every 2 drinkers. Enter your own numbers in the calculator for an exact count.
