Standard Bartender Hourly Consumption Formula
Industry standard hospitality formulas allocate 2 drinks per guest during cocktail hour and 1 drink per guest per subsequent hour. Total drinks are then apportioned by bar style. Standard 750ml wine bottles yield 5 glasses (5 oz pour); standard 750ml spirit bottles yield 16 mixed drinks (1.5 oz pour); beer is packed 24 cans/bottles per case; champagne toasts require 1 flute (4 oz pour = 6 pours/bottle).

Common Questions About Alcohol Calculator
Can unopened alcohol be returned after a wedding?
In many US states and regions, liquor retailers with wedding buy-back programs will accept returns of unopened, un-chilled wine and liquor cases with original seals and sales receipts. Always confirm your store's return policy before purchasing.
Should we do a formal champagne toast for all guests?
Serving a separate champagne toast often results in half-empty flutes left on tables. Many modern couples let guests toast with whatever drink they already have in hand, saving $300–$500 on separate sparkling wine bottles.
How much ice do we really need for a wedding?
Plan for 1.5 pounds of ice per guest for cooler chilling and drink service in mild weather, and 2.0 pounds per guest for summer outdoor receptions.
