Set the actual number, excluding guests choosing an alcohol-free toast. The toast is extra to the bar drinks.

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

  • What changes at a 125-guest wedding bar?
    At 125 guests, the baseline reaches 515 drinks, so bar layout starts to matter. Place water and nonalcoholic drinks away from the main alcohol queue when possible.
  • How many bartenders should serve 125 guests?
    The editorial prompt is 2 bartenders. Ask the bar service to confirm staffing for the menu, simultaneous arrivals and number of service points.
  • How much champagne is needed for 125 guests?
    A toast-only estimate for all 125 guests is 16 bottles. Reduce the toast-participant input for guests choosing a nonalcoholic option and plan their drinks separately.
  • Should I stock a full open bar for 125 guests?
    A full open bar can work, but a beer-wine-signature-drink menu is easier to forecast. Use the 6-bottle spirit estimate only if spirits are truly part of the plan.
