How Much Alcohol for 100 Guests Wedding?
A practical 4-hour baseline, serving conversions, bar-style options, and a local budget worksheet.
TL;DR - Quick Answer
For all 100 guests at a 4-hour wedding: 7 cases of beer, 33 bottles of wine, 10 bottles of liquor, and 17 bottles of sparkling wine for a separate toast. That covers a 500-drink reception baseline plus 100 toast pours, with no assumed non-drinkers or percentage buffer.

This baseline covers all 100 guests, with no assumed non-drinkers or percentage safety buffer. It uses 2 drinks in the first hour and 1 in each later hour:
Here's how the Standard Crowd profile splits those 500 reception drinks. Sparkling wine for the toast is separate:
Wedding Bar Styles for 100 Guests
The full-bar and signature-cocktail lists keep the standard 500-drink allocation. The beer-and-wine-only list explicitly reallocates those drinks 50/50. Sparkling wine remains a separate toast in every option.

Pro Tips for 100 Guest Wedding Bar
Staffing plan
Ask the venue or licensed bar provider to size staffing for the menu, service style, room layout and local requirements.
Confirm the return policy
If you use the calculator's optional 20% Safe Bet buffer, confirm the unopened-return policy before ordering.
Compare like-for-like quotes
Price the same brands, bottle sizes, taxes, delivery terms and return policy with each supplier.
Cold storage
Confirm refrigerated capacity and the supplier's chilling timeline for every product served cold.
Non-drinkers
The baseline covers all 100 guests. If you know the non-drinkers, reduce by their actual count and stock sparkling water, sodas, and mocktail ingredients.
Timeline for Ordering
Decide on bar style and create your drink list
Place orders for specialty items or large quantities
Pick up or receive delivery of all alcohol

Planning in the UK?
For a 100 guest wedding in the UK, use the same 4-hour serving targets: 165 beer servings, 33 wine bottles, 10 spirit bottles, and 17 sparkling-wine bottles for a separate toast. Price those quantities locally and add venue corkage; a US 24-beer case is a calculation unit here, not a standard UK pack size.
Ask suppliers for current pack sizes, unit prices, delivery terms and unopened-return policies. Ask the venue for its current corkage, storage and service charges before comparing outside supply with an in-house package.
UK pints are 568ml, so compare draught options by the supplier's stated serving capacity rather than equating one pint with one US bottle. Use the same separate-toast rule of 6 small pours per 750ml sparkling-wine bottle.

Should I have an open bar or limited bar for 100 guests?
An open bar offers more variety, while a limited bar narrows the inventory to beer, wine, and perhaps one or two signature cocktails. Compare written quotes for the same service window, and treat a separate sparkling-wine toast as its own quantity.
