Wedding Alcohol Calculator

How this works

Event bar planning typically assumes each drinking guest has about one drink per hour. Multiplying guests × hours × share of drinkers gives total drinks needed, which this calculator splits across wine, beer, and liquor using a common 40/40/20 mix, then converts each into bottle counts (5 glasses per wine bottle, 1 beer per bottle/can, about 17 drinks per 750ml liquor bottle).

Source: Based on the common event-planning rule of one drink per guest per hour, with a typical 40% wine / 40% beer / 20% liquor mix used by wedding and catering planners.
