Common Questions About Wedding Drink Calculator
How much alcohol do I need for 100 wedding guests?
For a 5-hour reception with 100 drinking guests, plan for approximately 500 drinks total: ~50 bottles of wine (about 4 cases), ~150 beers (about 6.5 cases), and ~7 bottles of liquor (if serving cocktails).
Is a champagne toast necessary at a wedding?
No. Many modern couples skip the dedicated champagne toast. Instead, have the DJ or MC announce: 'Please raise whatever beverage you currently have in your hand for the toast!' This saves $300–$600 on wasted champagne flutes that are only sipped once.
Can I return unopened alcohol after the wedding?
In many US states (and countries), large liquor retailers like Total Wine or BevMo permit returns of unopened, undamaged cases and bottles with receipts. Always check your local state liquor laws and retailer policy in advance.
How much ice should we buy for the wedding bar?
Calculate 1.5 pounds of ice per guest for indoor receptions, and 2 pounds per guest for warm outdoor summer weddings. For 100 guests, that means 150 to 200 lbs of ice.
