How Many Glasses in a Bottle of Wine?

How Many Glasses in a Bottle of Wine?

Jonas Muthoni

A brief answer to this question is: there are about 5 servings of wine in a bottle.

While certainly a piece of trivia, this is great practical knowledge and vital to consider when preparing to host an event.

A standard serving of wine is 5 ounces. A standard bottle of wine contains 750 ml. So, determining the number of servings per bottle requires calculating how many ounces are in 750 ml. 5 oz is approximately 150 ml, so 750 divided by 150 gives us about five servings of wine per bottle.

While 5 oz is a standard pour, it’s common to pour just above or below that line depending on the alcohol content.

Larger servings are common for lower alcohol wines like Moscatos and Rieslings. If you’re drinking a wine that’s 15% ABV or more, however, the serving should be below the standard pour line. Servings of port, which is typically 20% ABV, are usually 3 oz, for example.

Of course, wine glasses hold a lot more than these recommended pours. Always avoid temptation to fill the glass right up to the top. Wine glass shapes and sizes are meant to enhance the drinking experience.

How Many Bottles Are There In A Barrel Of Wine?

This is another matter of math that’s an excellent consideration if you’re thinking of getting into winemaking. The answer depends on the type of barrel. There are a range of barrel sizes with different capacities:




112 liters (30 US gallons)


225 liters (59 US gallons)


228 liters (60 US gallons)

300 liters (79 US gallons)


500 liters (132 US gallons)


600 liters (158 US gallons)

The most common types are Bordeaux and Burgundy, which would yield 300 and 304 standard bottles of wine respectively. (Just for fun, that’s about 1,500 and 1,520 standard glasses of wine!)

In the US, it’s legal for a single-adult household to produce 100 gallons of wine per year for personal use. Households with two or more adults can make 200 gallons.

How Many Calories In A Bottle Of Wine?

Wine is often touted as beneficial to your health, though be aware that a lot of the headlines oversell the studies. (A glass of red wine is not equivalent to an hour at the gym, for example, as much as I would like it to be true!) It’s true that wine has no cholesterol and no fat, but it is by no means calorie free.

A glass of wine has between 110 and 300 calories per serving, depending on the style.

What Are The Top Ten Grape Varieties In Winemaking?

Cabernet Sauvignon is the most grown grape for winemaking, with plantings in almost every major wine-producing country. According to this 2018 Forbes article, the top ten include:

  1. Cabernet Sauvignon, 840,000 acres (340,000 hectares)
  2. Merlot, 657,300 acres (266,000 hectares)
  3. Tempranillo, 570,800 acres (231,000 hectares)
  4. Airén, 538 700 acres (218 000 hectares)
  5. Chardonnay, 518,900 acres (211,000 hectares)
  6. Syrah, 470,000 acres (190,000 hectares)
  7. Grenache Noir, 402,780 acres (163,000 hectares)
  8. Sauvignon Blanc, 299 000 acres (121,000 hectares)
  9. Pinot Noir, 285,000 acres (115,000 hectares)
  10. Trebbiano Toscano / Ugni Blanc, 274,300 acres (111,000 hectares)

What Country Produces The Most Wine?

Italy produces more wine than any other country. According to data from the Wine Institute, Italy produced almost 5 million liters of wine in 2015, accounting for just over 17% of total wine created throughout the world. France and Spain followed close behind with the US in a distant fourth.

More recent surveys showed that this trend has remained the same through the years, despite lower harvests due to frost and heavy rains. Numbers are expressed in hectoliters. (One hectoliter = 100L, so the volume for Italy would be 4.85 million liters.)

Country 2016 2017 2018
Italy 50,900 42,500 48,500
France 45,200 36,600 46,400
Spain 39,700 32,500 40,900
United States 23,700 23,300 23,900
Argentina 9,400 11,800 14,500
Chile 10,100 9,500 12,900
Australia 13,100 13,700 12,500
China 11,400 10,800 10,800
Germany 9,000 7,500 9,800
South Africa 10,500 10,800 9,500

An interesting point of trivia is that the state of California alone produces about 90% of US wines, which would put that state alone in fourth place on this list!

Countries That Drinks The Most Wine?

We know now who makes the most wines, but what country drinks the most wine?

In breaking down consumption of wine per capita, the top wine drinking populations in the world are:

Vatican City may seem an unlikely candidate for this statistic, perhaps explained away by sacramental wine. Turns out this is not so, and the impressive number truly reflects the lifestyle and demographics of those living there.

The US’s consumption per capita is significantly lower than the top countries. Despite this, the US tops the list of for overall wine consumption in the world. According to the Wine Institute, consumption has been steadily on the rise in recent decades, too.

It’s not surprising, given how easy it is to get delicious, local wines these days. Although California produces the lion’s share of American wines, wine is produced in all fifty states.

This is what a serving of wine actually looks like

So we have agreed that there are five servings of 5 ounces in each bottle of wine.

But what does that look like?

Each wine glass is different and there really isn’t a fool-proof way to get it exact each time. We have all ordered a glass of wine at a restaurant and been quite disappointed with the….lack of wine that is served to us. We have been in a situation where you are sharing a bottle with friends and the last person gets jipped with less wine than everyone.

A good way to gauge where you should pour the wine is the area of the glass that goes from the bowl shape to the straight part of the glass. Pouring the wine just above this part of the glass is almost always 5 ounces. (Check out the picture above and note that all of those wines are poured a bit above the bowl part of the glass.)

Tip: For those who work as bartenders, servers, or tasting room associate, a great trick is to have a mock glass filled with sand at the 5-ounce mark. Get out a food scale and pour wine into the glass at 5-ounces. Have an empty glass beside it and fill it with sand or mark it where the wine should be filled. Have this at the bar so you can help yourself measure proper portions of wine.

How Many Drinks A Day Is Bad?

Alcohol is obviously bad when drank in excess.

But how many glasses of wine a day is too much?

Many studies suggest that having one glass a day of red wine is beneficial, but having more than two drinks a day can be harmful to your health. To even it out, we recommend not having more than one glass of wine per day, or no more than two glasses of wine a few times a week.

That’s a wrap!
