How Much Alcohol Should You Buy for a 100-Guest Wedding?

Buying alcohol for 100 wedding guests sounds like a simple calculation, but the guest count is only the starting point. A four-hour reception with beer and wine needs a different shopping list than a five-hour celebration with two signature cocktails and a full bar.

At Whiskey & Copper, you purchase the alcohol, and we help plan what to buy based on your menu and event details. Here’s how to start thinking through the quantities.

Start With Your Bar Menu

Decide what you’ll serve before counting bottles. Will guests have beer and wine only? Beer, wine, and two signature drinks? Or a wider selection of cocktails?

A focused menu makes planning easier. If you’re offering signature cocktails, choose drinks with different base spirits or flavor profiles so guests have a real choice. Include appealing alcohol-free beverages for guests who want them.

Estimate Who Will Drink Each Option

Not every guest will drink alcohol, and those who do won’t all order the same thing. Consider your guest list, the time of day, the length of service, and whether dinner is included.

Then think about preferences. If your crowd loves margaritas, tequila may be a bigger part of the shopping list. If they mostly drink wine, a standard “one of everything” bar could leave you with spirits you didn’t need.

Plan for the Length and Style of Service

Cocktail hour can create a rush of orders. Dinner, speeches, and dancing change the pace throughout the event. An outdoor Texas wedding may also call for more water, ice, and refreshing alcohol-free choices.

These details affect both the quantities you purchase and the bar setup you need. A bottle estimate alone won’t tell you whether you have enough mixers, garnishes, ice, or staff.

Build a Shopping List From the Actual Menu

Once you’ve chosen your drinks, estimate the number of servings you expect for each category. From there, convert cocktail servings into spirits and other ingredients using the recipes you plan to serve. Count beer by the can or bottle and wine by the planned pours.

Check your venue’s rules and retailer’s return policy before buying extra. Your final list should include alcohol, mixers, garnishes, ice, and alcohol-free beverages.
