Vintage Roots' Selection of Organic and Biodynamic Wines


Have you ever wondered how many glasses in a bottle of wine there are? If you're the average person, probably not! You simply pour the wine into your glass until you decide you have the right amount, and you enjoy.

There's no need to think about the number of glasses of wine you get from a single bottle unless you work at a restaurant.

But, if you want to be an educated, cultured connoisseur of wine, these are the kind of things you need to know! In this Wine 101 post, we'll teach you everything you need to know about the contents of that bottle of wine…

How Many Glasses in A Bottle of Wine?​

Before we can answer this question, you need to know how much wine each bottle contains, as well as how many milliliters (ml) of wine should be served in each glass.

In a bottle of wine, there are 750 milliliters, 75cl or 0.75 litre. Wine bottles aren't quite litre-size, but your average wine bottle will contain 750ml. of wine.

But how much should you serve in each glass of wine? That's a tougher question to answer:

  • For wine tastings - When you are enjoying a wine-tasting, the average serving size, is roughly 60ml. If you stick with this serving size, you can get roughly 12 wine tasting-size glasses.
  • For dinner parties - At a dinner party, you'll serve about 125ml. So, if you're wondering how many 125ml glasses in a bottle of wine, you will get 6 glasses of wine from your bottle.
  • For private drinking - When you are drinking at home, it's normal to serve up to 175ml of wine. For those who want to know how many 175ml glasses in a bottle of wine, you can expect just over 4 glasses.
  • For drinking at a bar or restaurant - Your average bar or restaurant will usually offer 125ml, 175ml and 250ml size servings. By law restaurants and bars must offer a 125ml option, but by far the most sales are done in 175ml and 250ml (medium or large) serves. It is worth remembering that a 250ml serving is a whole third of a bottle.

How Much Wine Served Per Type

Here's something to keep in mind: not all wine is served in the same quantities!

Red and white wines are usually served alongside food, and they are served in larger wine glasses - capable of holding up to 500ml of wine. Of course, you never top off your wine glass completely, so the average serving size of a glass of wine at a restaurant will be close to 175ml.

  • How many LARGE glasses of wine in a bottle of red or white?
    You'll usually get no more than 4 glasses in total.​
  • How many SMALL glasses of wine in a bottle of red or white?
    You'll usually get as many as 6 or 7, depending on the serving size.

Of course, you don't always get the same amount of wine when drinking other types of wine:​

  • Champagne and Sparkling wine

Can often be a smaller average serving, 125ml being more usual. Champagne served as a toast at special celebrations for example​.

The average serving size of rosé wine is between 60 and 125 ml, unless at a dinner party (see serving sizes listed above…)​

How Much Wine to Serve Per Person?

This is when things start to get a bit tricky! You have to calculate the right amount of wine per person depending on the occasion, meaning you have to figure out how many bottles of wine to buy. Headache central, right?

Here's what you need to know:​

Wine tasting  

Wine tastings are all about giving your guests a wide selection of wine to taste from, but only in small quantities. The average 60 ml glass of wine served at a wine tasting is half the size of the wine drunk at parties or social events.

You can usually get away with up to 6 glasses of wine per person without worrying about inebriation or overdrinking.​

​Eating out  

If you are drinking wine with dinner at a restaurant, you should stick with 2 to 3 glasses per person. You can stick with one type of wine if you want, or try a few different wines with the various courses (if you're eating a multi-course meal). The key is moderation, and pairing wines with the food.

​Wine/cheese tasting

This is a way to expand your palate and experience the wonder that is the pairing of wine and cheese. You will keep your cheese options limited, so you'll want to limit your wines as well.

You can stick with the smaller servings of wine (60ml per glass), so you can have up to 6 small glasses of wine with the meal.

Dinner party  

The rule of thumb at a dinner party is three glasses of wine per person. This helps people to relax without pushing them over the edge into inebriation, slurring or falling asleep! This means you'll need two bottles of wine per three people, give or take.​

Getting the serving sizes right is the key to safe, healthy wine drinking. Avoid overdoing it at wine tastings, dinner parties, and celebrations, and you'll enjoy your wine a whole lot more!​

Nifty Tip: Nail that Serving Size

Want to get your serving sizes just right? Pour exactly the right amount of water into a wine glass, and use a marker to mark the level. All you'll need to do is fill that wine glass to the right level, and transfer the wine into the fresh glasses. It's the best way to get a perfectly even serving size.

Or fill an empty wine bottle with water and see if you can guess how much to pour into a glass to get a typical 125ml serving. If you get it right, you should be able to pour the sixth glass to the same level as the first. Why not see if you are a natural expert?! (6 x 125ml glasses is one 750m bottle exactly)​

How Long to Keep Serving with the Same Bottle

What happens if you run out of guests before you empty a bottle of wine? No worries! Unless you're serving champagne or sparkling wine, your bottle should last for up to 3 days after being opened. Simply replace the cork, store in a cool, dry place, and serve for up to 3 days.​
