Do the Wine Math: It’ll save your party every time.
I get asked a lot about how much wine is needed for a party and my answer is always the same: do the Wine Math.
No, it’s not New Math which is very complicated and completely unnecessary. It’s Old Math where we use addition, multiplication and a very small amount of division. All you need are some numbers to start.
Wine math is just that simple. First you have to know how many glasses are in a bottle. Then you need to figure out the kind of party you’re having, how long it will last, the number of people that are coming, and exactly who you’ve invited (meaning what type of wine drinkers they are). Once you figure all of that out, it’s a very quick calculation.
Of course, if you’re having a break-up pity party with just you and a friend then who cares about math at all? Important fact: two very large mason jars will hold about a bottle of wine. Simply add your favorite chick flick and you’re good to go!
Let’s get back to the very important wine math. A standard bottle of wine is 750 ml which is approximately 25 ounces. You will find that the suggested serving of a glass of wine is 5 ounces so that would mean that each bottle would pour about 5 glasses. However, I don’t think anyone pours exactly 5 ounces of wine – it usually ends up closer to 6 ounces – which means that, on average, a bottle of wine will hold about 4 glasses of wine. Use that as your ‘rule of thumb’.
So, think about how your guests will drink. You will pour one glass before dinner, a couple more will be consumed during the meal, and probably one more after dinner. That means, assuming that there are 4 glasses in a bottle, that you would need about one bottle per guest. But, as I’ve said above, you also need to consider a couple of other variables before you hit the wine store.
Guest Count – hopefully your friends are the type that will actually RSVP and not just show up unannounced. Always add two more people to the count because someone will bring a random extra that they ‘forgot’ to tell you about or you have that one friend who never RSVPs and never shows but who will decide to come to your fabulous event.
Here’s where you pull out the calculator for the wine math:
Multiply the number of guests times the number of estimated glasses filled per guest.
THEN divide that number by 4 (approximate glasses per bottle) and that equals the number of bottles needed.
How much wine will they drink? Nobody can perfectly predict this but there are a couple of ‘rules’ that you can always depend on. If your guests at least like wine they will drink one glass in the first hour but if they enjoy wine or even love it the number will be closer to 2 glasses in that first hour. For each hour after that add one more glass to the count. Following this logic – if your party will last about 4 hours most will drink close to 5 glasses of wine. You will need both a red and a white and enough of each in case most of your guests want to drink one or the other.
Now, if you’re like me and you are pouring Champagne, the whole calculation goes out the window because a bottle of bubbles will pour approximately 8 champagne flutes. Unless, however, you’re at my house then a bottle will only hold 6-7 flutes because I have really large champagne glasses!
See? “Wine math” made easy. Now go and enjoy your party!
