Cost = bar drinks + individual toast pours, multiplied by your price. This is a service allowance, not the purchase price of rounded bottles/cases. Replace the starter price with your quote; taxes, staff, delivery and corkage are excluded.
What these quantities assume
The 82% drinking share, five-hour bar, one drink per hour and 35/45/20 beer/wine/spirits split are Weddenly's editable examples, not survey results. Count non-drinkers separately and confirm the order with your bar supplier.
Drinking guests are rounded first. Drinks = drinking guests × bar hours × pace, rounded up. Beer and wine are allocated first; spirits use the remainder. Bottles and cases are rounded up after allocation.
One case = 24 beers. A 750 ml wine bottle gives 5 × 150 ml pours; a 750 ml spirit bottle gives 17 × 44 ml pours. A 750 ml sparkling bottle gives 8 × 90 ml toast pours. Mixers use an editorial 100 ml per spirit drink, rounded up to liters. These are serving assumptions, not safe-consumption guidance.
Cost = bar drinks + individual toast pours, multiplied by your price. This is a service allowance, not the purchase price of rounded bottles/cases. Replace the starter price with your quote; taxes, staff, delivery and corkage are excluded.
Guest-count FAQs use one bartender per 75 guests only as an editorial conversation starter. Ask the bar service to set staffing for your menu, arrival rush and service points. Water, alcohol-free drinks, ice, storage and venue permissions need their own confirmed plan.

FAQs
- How many total drinks do 100 wedding guests need?
With default assumptions, 100 guests become about 82 drinking guests and 410 total drinks. Shorten that if your bar opens only after dinner. - How should I split wine and beer for 100 guests?
The starter split gives 37 wine bottles and 6 beer cases. Match the split to the meal: dinner-heavy events often lean wine, outdoor receptions often lean beer. - How many spirit bottles should I plan for 100 guests?
The default spirit share estimates 5 bottles. If you are serving only two signature drinks, convert this into the exact liquors those recipes need. - How many champagne bottles cover a 100-guest toast?
Plan about 13 bottles for a toast pour. Confirm flute size with the venue because heavy pours can change the count quickly.
