You have figured out what kind of wine you like to drink. You have figured out the most delicious meal to serve it with, and now you are going to invite your closest friends over to share both. But as you're driving around town and debating whether to fold your cloth serviettes or use your brass napkin rings, one other mammoth consideration pops into your head—how much wine should you serve?

When Math and Wine Collide

There is probably no worse time (or better time, depending on how you look at it) to try to do math than when you're drinking wine. But there is a very simple formula that one longtime industry veteran ascribes to. "I was raised that you never want someone to have an empty glass," says Paula Kornell, the proprietress of Paula Kornell Sparkling Wine.

If you are having a cocktail party and a dinner, you should plan on about half a bottle per person.

Kornell's father, pioneering winemaker Hanns Kornell of Kornell Champagne Cellars, was known for his impromptu dinner parties, with her mother Marilouise doing the cooking. Safe to say Kornell is a de facto expert on how much wine to serve at such a soirée. "Nowadays you have to be really careful that people don't drink too much, but if you are having a cocktail party and a dinner, you should plan on about half a bottle per person."

OK, so let's do the math.

Math Problem #1: You have 10 people coming over for dinner. How many bottles should you have?

Answer: Kornell thinks you should have five or six bottles. "If it's five or six, I would err on the larger number. You never want to be the hostess who runs out of alcohol."

Math Problem #2 (for extra credit, since this one is harder): Why is half a bottle the right amount?

Answer: A typical bottle of wine contains 750mL of enhanced grape juice. When you convert 750mL to fluid ounces, you get exactly 25.3605. A typical can of beer or soda is 12 fluid ounces, or just under half the 25.3605 ounces. So, a half a bottle of wine is roughly a little bit more liquid than one beer or soda.

Obviously, that doesn't sound like a lot, especially, as Kornell says, for a cocktail party followed by dinner. But we must remember two things:

  • Some people will drink more, and some people will drink less
  • When we say a "glass" of wine, we don't think of it in the same way as a "glass" of water, meaning, we don't fill the wine glass all the way to the top like we do with water
You figure you have a glass when you first get there, and then maybe two to three more during dinner. You want to be safe but not run out.Paula Kornell, Paula Kornell Sparkling Wine

Most glasses of wine are in the 3- to 4-ounce range, so—again, math—you would get about three or four glasses out of half a bottle. Which, according to Kornell, sounds about right. "You figure you have a glass when you first get there, and then maybe two to three more during dinner. You want to be safe but not run out." And, of course, safety is a serious subject.

Nobody wants to drink too much and then drive home, endangering themselves and others. It's responsible beverage service to monitor your guests and ensure they make it to your next dinner party, so always have plenty of water and small pieces of bread or snack foods—sometimes called "bites" in the industry—on hand to absorb some of that enhanced grape juice.

If you are throwing a wedding, housewarming party, 40th birthday party, or any other big bash, you may be wondering how much alcohol you need for your party. Luckily, we’ve got a handy party drink calculator to make sure you don’t way overspend on alcohol but are sure to have enough. And if you read our How Many Glasses Do You Need? blog, you may be searching for some additional information on how much alcohol to actually buy to go in those glasses.

Party Drink Calculator

Plan on one drink per guest for each hour of your function.  This should ensure you have enough alcohol for your party (unless you are having a college fraternity party – then you may have to rethink your calculations).  Here’s the formula behind the party drink calculator:

# of guests x hours of party time

Let’s assume you are throwing a 4 hour party for 250 guests.  In other words, you will need 250 guests x 4 hours = 1000 drinks.

Now, let’s assume you will serve beer, wine, and mixed drinks.

BEER: How Much Do You Need?

40% of all party drinks are beer.  So you will need to use:

# of total drinks x 40%

or

1000 x 40% = 400 beers

We recommend bottled beer but if you are having a keg, you need to make sure you can serve 400 beers.  (NOTE: Most kegs contain 15.5 gallons of beer or 165 12-oz servings.)

WINE: How Much Do You Need?

Wine accounts for 60% of all remaining drinks.  So you can use the formula:

(Total # of Drinks – Beers) x 60%

or

(1000 – 400) x 60% = 360 glasses of wine

A standard bottle of wine (750ml) serves approximately 6 glasses, but unless you are really careful about how much you are pouring, you may not get the full 6.  I like to use 5 glasses per bottle for my calculations, then you are sure to have enough.  To figure out how many bottles you will need, you can simply divide the total number of glasses you need by 5.  In this case: 360 glasses of wine / 5 glasses per bottle = 72 bottles of wine needed.

Now you need to decide how many bottles of red, white, and sparkling wine you need.  Consider whether the event is an indoor/fall, winter, spring event or an outdoor/summer event.  At an indoor/fall, winter, spring event people will drink more red wine so you should plan for 50% of the bottles being red, 25% white, and 25% sparkling.  In our example, this would mean you need 36 bottles of red, 18 bottles of white, and 18 bottles of sparkling.  If you are planning an outdoor/summer event, you can split the bottles evenly between red, white and sparkling.  Using our numbers, this would mean you needed 24 bottles of each red, white, and sparkling.

When buying multiple bottles of wine, you will definitely want to buy it by the case.  I always round up to the next case.  Having a few extra bottles ensures that you will not run out and maybe you will have a few bottles left over for hostess gifts or to drink while you wind down!

SPIRITS: How Much Do You Need for Mixed Drinks?

Any drinks that are not wine or beer will fall into the mixed drink category.  You can calculate this as:

Total # of Drinks – Beer – Wine = # of Mixed Drinks

Calculating what you need to buy for this category is WAY trickier and depends entirely on the types of mixed drinks you will be serving.  Limiting the choices to one or two “signature cocktails” can help you decipher how much alcohol and mixers you will need to purchase.

The average cocktail uses:

  • 1 1/2 ounces (the average shot) of a base liquor (ie. Vodka, gin, rum, etc.)
  • Accent juices (ie. lemon and lime) usually use 1/4 to 1/2 ounce
  • Filling a highball or tall drink with juice or soda often requires 4-6 ounces of the mixer.

For example, if you are making mojito which contains rum, lime juice, and club soda, you can assume you need 1.5 oz rum, 1/4 oz lime juice, and 4-6 oz club soda.  You just need to figure out how many ounces your bottle of rum contains, and divide that by 1.5 to know how many cocktails you can make with that bottle and then do the same with your accent juices and mixers.

How much CHAMPAGNE do you need?

If you are serving champagne for a champagne toast, you will need one bottle of champagne for every 8 guests.  This should give you enough champagne to have 1/2 glass for each guest for the toast.  In our example, this would be 250 guests/8 = 31.25 bottles of champagne (rounding up, you need 32 bottles).

Don’t Forget the Water

How much wine per person for a party

In all the discussion about how much alcohol to buy, don’t forget that all guests will need water at some point in the event.  Make sure you have plenty!  You can estimate that guests will drink about 12 ounces every 1/2 hour – hour during the party.  We recommend tap water where possible to help preserve the environment.  Did you know that only 8% of plastic water bottles are actually recycled?  That leaves a lot of water bottles filling up our landfills!  If serving tap water you need to account for 4 12-oz glasses per person or 1000 glasses of water.
