How many ml fit in a Champagne flute?

A champagne flute is a tall, narrow glass specifically designed for drinking champagne and other sparkling wines. The shape of the flute is optimized to preserve the bubbles in the wine and channel them upwards to enhance the drinking experience. But just how much champagne can a standard flute hold?

Quick Answer

A typical champagne flute holds around 150-180 ml of champagne. Most standard flutes range in capacity from 120-220 ml. So on average, a champagne flute will hold around 6-8 ounces or around a half cup of liquid.

Measuring Champagne Flute Capacity

Champagne flutes can vary slightly in size and capacity. Here are some of the factors that influence how much a flute can hold:

  • Height – Standard flutes range from 6-10 inches tall. Taller flutes can hold more.
  • Diameter – Typical flute diameters range from 2-3 inches. Wider flutes hold more volume.
  • Thickness – Thinner glass allows for a larger inner capacity.
  • Shape – Some flutes have a tapered bowl vs a straight-sided bowl. Tapered bowls may have less capacity.

But most champagne flutes, regardless of exact dimensions, hold a relatively standard capacity in the 150-180 ml range. The easiest way to determine the exact capacity of a specific champagne flute is to carefully fill it with water and then pour the water into a measuring cup to check the volume.

Champagne Bottle Sizes

Understanding champagne flute capacity also requires looking at the typical bottle sizes of champagne and other sparkling wines:

  • Standard Bottle – 750 ml – The standard full-size bottle of champagne contains 750 ml, which is about 25.4 ounces. This is enough to fill approximately 4-5 champagne flutes.
  • Magnum – 1.5 L – The magnum is 1.5 L, double the size of a standard bottle. It holds enough to fill 8-10 flutes.
  • Jéroboam – 3 L – The jéroboam is equivalent to 4 standard bottles. It holds 3 L and can fill around 16-20 flutes.
  • Methuselah – 6 L – The methuselah holds 6 L, filling over 30 champagne flutes.

Knowing the bottle size makes it easier to estimate how many pours you’ll get from one bottle based on the capacity of your specific champagne flutes.

Champagne Pour Sizes

In addition to flute capacity, champagne pour sizes also vary:

  • A standard pour is around 4-6 ounces.
  • A generous pour may be 6-8+ ounces.
  • A tasting pour may be as little as 1-2 ounces.

With a standard 750 ml bottle and 6 ounce pours, you can expect to get around 5-6 glasses filled. Smaller pours allow you to stretch a bottle further.

Factors that Influence Capacity

There are a few additional factors that can influence how much champagne a flute can hold:

Type of Champagne

The type of champagne can impact capacity as well. Champagne produces two sizes of bubbles:

  • Large bubbles – Sparkling wines like prosecco produce larger bubbles that take up more volume.
  • Small bubbles – Champagne produces tiny bubbles that take up less space in the glass.

As a result, flutes filled with a large-bubbled sparkling wine may have slightly less liquid volume than one filled with small-bubbled champagne.

Head Size

The head refers to the frothy foam that accumulates at the top of a poured glass of champagne or sparkling wine. Champagnes that produce a larger frothy head will take up some of the volume in the glass, meaning less liquid can fit.


More effervescent champagnes produce more bubbles and carbonation. Increased carbonation can cause the liquid to expand slightly, taking up more capacity in the glass. Less effervescent wines may allow you to technically fit more liquid volume.

Glass Shape and Design Impacts

The design and shape of the champagne flute impacts capacity as well. Here are some variations and their effects on volume:

Tulip Shape

Tulip champagne flutes have a narrow base that gradually widens into a wider bowl at the top. This shape helps preserve carbonation but reduces overall liquid volume capacity.

Trumpet Shape

Trumpet-shaped flutes have a wider base that tapers slightly into a narrower opening at the top. This allows more liquid volume but fast bubbles and loss of carbonation.


Cylindrical, straight-sided flutes maximize the liquid volume while still retaining bubbles fairly well. However, the wider body impacts the rate of bubble rise.

Etched Bottoms

Laser-etched bottoms add nucleation points to help bubbles form and rise quickly. However, the etching displaces some liquid volume in the base of the glass.

Dimpled Bottoms

Small dimples in the bottom of the flute also impact bubble formation. But like etching, they reduce the inner capacity slightly. Smooth, unetched bases maximize liquid volume.

Stemware Etiquette

Holding a champagne flute properly by the stem prevents body heat from warming the wine. However, covering the bowl with your fingers reduces the interior space and may displace some liquid when lifting. Holding by the base only can maximize the liquid capacity.

Glass Thickness

The thickness of the glass also changes the interior dimensions. Thinner glass maximizes the available liquid volume. Thicker, heavier glass reduces the capacity slightly.


In summary, a standard champagne flute holds an average capacity of around 150-180 ml. However, many factors impact exact capacity and pour volume, including glass shape, dimensions, thickness, and pouring technique. When entertaining, carefully consider your champagne flute size, bottle formats, and desired pour size to ensure you have sufficient glasses for all your bubbly.


Why are champagne flutes tall and narrow?

The tall, narrow shape is designed to preserve carbonation. The narrow bowl minimizes surface area through which bubbles can escape, while the tall sides encourage bubbles to rise quickly to the top.

What is the ideal champagne pour?

The ideal pour is around 4-6 ounces. This allows room for the frothy head to form without overflow. Filling too high will cause bubble loss and a flat drink.

How much head space should be left in a champagne flute?

Leave about 1 inch of head space between the rim and the liquid. This allows for the frothy foam that develops on top after pouring.

Should you fill a champagne flute all the way to the top?

No, you should avoid filling all the way to the rim. Champagne needs head space to develop its carbonation and aroma. Filling too high will cause it to quickly overflow and lose bubbles.

Does champagne flute size matter?

Yes, the flute size impacts the drinking experience. Too small and the wine will warm too quickly. Too large and the bubbles will dissipate. A flute around 150 ml is ideal for maintaining carbonation and chilled temperature.

Champagne Bottle Volume Number of 6 oz Pours
Standard 750 ml 5
Magnum 1.5 L 10
Jéroboam 3 L 16
Methuselah 6 L 32

This table summarizes common champagne bottle sizes and the approximate number of 6 ounce pours each holds, assuming a 150 ml champagne flute capacity.

The Ideal Champagne Flute

The perfect champagne flute strikes a balance between preserving bubbles and maintaining ideal capacity. Use this checklist when selecting flutes for an optimal experience:

  • Height between 8-10 inches
  • Diameter between 2-3 inches at widest point
  • Thin, light glass construction
  • Tapered bowl shape
  • Smooth, unetched base
  • Stemmed design to hold by base
  • Capacity between 150-180 ml

With the right flutes and pouring technique, you can maximize the delightful flavor and sensation of drinking fine chilled champagne and sparkling wines.
