Weddings & Large Events calculators
At wedding scale, small per-guest errors become expensive: half a drink per guest is fifteen extra bottles at 150 guests, and an over-poured champagne toast strands cases of unopened bubbly. These calculators are built for three-digit guest counts — full-bar quantities split across beer, wine and spirits, and a toast calculator that works in pours per bottle rather than glasses of wine — using the same sourced standard-drink math as the rest of the site.

Which calculator should I use?
Start with the wedding alcohol calculator: pick the split preset that matches your crowd (beer-heavy backyard, balanced, or wine-and-cocktails) and it returns cases of beer, bottles of wine and 750 ml bottles of spirits for your reception length. The champagne toast is a separate, smaller purchase — one 4 oz pour per adult, six pours to the bottle — so use its dedicated calculator rather than folding it into the bar. For cocktail-hour food, the appetizers calculator in Party Food works per hour and scales to any headcount.
