How to Calculate the Amount of Wine You’ll Need at Your Event

When throwing a party, the last thing you want is to run out of wine. After all, it’s a celebration—not a time to stress out. Whether a fundraiser or wedding reception, here’s the one equation that will help you figure out how much wine to purchase before your special event.

How many people are you expecting?
Start with the number of attendees—age 21 and over, of course. Take this number and divide by one of the following:

What else will be served?

  • If there will be dinner, use the number 2
  • If there will be a full bar, use the number 2.5
  • If you know most of the attendees prefer alcohol other than wine (like beer), use the number 2.5
  • If there won’t be dinner (or another meal), use the number 2.5

What is the result?
After dividing the number of adult attendees by 2 or 2.5 per the above situations, the resulting number is how many wine bottles you should buy.

Plus, add an extra few bottles to your count. “Always a little buffer should be stashed away,” says our special events manager, Sally Allred. “We all know those guests who enjoy a little extra splash before they hit the dance floor!”

Sally also recommends a 50/50 split between red wine and white wine. “But you should consider factors like weather on the day of your event or time of your event, too.”

What if there’s a champagne toast?
We like your style. A good rule of thumb is dividing the number of attendees by 8. This will provide each guest with half a glass of bubbles for the toast.

In any atmosphere—even if a sit-down meal isn’t being served—keep in mind food. It doesn’t need to be fancy or expensive, but you don’t want your event to get out of hand.
