About WeddingDrinkCalc

“How much alcohol do we buy?” is asked in the last two weeks of almost every wedding plan, usually in a liquor-store aisle. WeddingDrinkCalc exists so the answer takes thirty seconds at home instead: guests, hours and crowd type in — beer, wine, spirits, champagne, a shopping list and a budget out.

The math is deliberately unoriginal. It is the catering industry's standard rule of thumb — one drink per drinking guest per hour, a sensible split, standard bottle yields, a 10% buffer — written down in full on the formula page so you can check every step. The content is original to this site; the conventions belong to everyone who has ever run a bar.
