What is sparkling wine?

Quick answer

Sparkling wine is wine with enough dissolved carbon dioxide to create visible bubbles and a lively, tingling texture when the bottle is opened and the wine is poured.

The carbon dioxide can come from fermentation. In the traditional method, a second fermentation happens inside the bottle. In the tank method, it happens in a sealed pressure tank. Some sparkling wines are carbonated by adding carbon dioxide mechanically instead.

This means sparkling wine is a broad category, not one single style. It may be white, rosé or red; dry or sweet; light and fruit-driven or richer and more savoury.

Champagne is one particular type of sparkling wine: it comes from France’s Champagne region and must meet the region’s rules. Sparkling wine made elsewhere should not be called Champagne.

What makes wine sparkling?

The bubbles come from dissolved carbon dioxide. When the bottle is opened, pressure falls. The gas then leaves the wine, forming bubbles that rise through the glass.

That release is called effervescence. It is the visible bubbling and lively sensation associated with sparkling wine.

The useful distinction from still wine is not colour, sweetness or grape variety. It is the presence of noticeable, intentional effervescence.

How are the bubbles made?

During fermentation, yeast converts sugar into alcohol and carbon dioxide. Usually, much of that gas escapes. For sparkling wine, winemakers retain the gas by carrying out a further fermentation in a sealed environment.

Traditional method

In the traditional method, the second fermentation takes place in the bottle in which the wine will eventually be sold.

The wine may then spend time ageing on lees, the yeast sediment left after fermentation. This can contribute developed flavours and aromas such as toast, biscuit, bread or savoury yeast.

“Traditional method” describes how the wine was made. It is not, by itself, a guarantee that one wine is better than another.

Tank method

In the tank method, the second fermentation takes place in a sealed pressure tank rather than in individual bottles. The wine is then bottled under pressure.

This approach is commonly associated with fresh fruit and floral characters, although the final style depends on the grapes, winemaking and ageing.

Carbonation

Some sparkling wines are made by mechanically adding carbon dioxide to the wine. This is called carbonation.

It is a different production approach from creating bubbles through a second fermentation. The method itself is not a complete judgement of quality; it simply tells you where the gas came from.

Other methods exist too, including transfer and ancestral approaches. They are useful terms to encounter, but they need not turn a beginner’s definition into a technical production manual.

Is sparkling wine the same as Champagne?

No. Sparkling wine is the broad category. Champagne is a protected geographical name for qualifying sparkling wine from the Champagne region of France.

So these statements are accurate:

• Champagne is sparkling wine.
• Not all sparkling wine is Champagne.
• Australian sparkling wine should not be labelled Champagne.
• “Champagne” should not be used as a casual synonym for any fizzy wine.

Prosecco is another regulated name associated with Italian wine production. It is commonly encountered as a fresh, tank-fermented sparkling style, but the Prosecco DOC denomination also covers semi-sparkling and still wines under its production rules.

What styles of sparkling wine are there?

Sparkling wine has much more variety than the standard image of a pale, dry drink for celebrations.

White, rosé and red

Sparkling wine may be white, rosé or red—including Australia’s distinctive sparkling Shiraz style. Colour comes from the grapes and winemaking choices, not from whether the wine is sparkling.

Dry through sweet

Sparkling wines range from very dry to sweet. Terms such as brut describe sweetness levels rather than the presence or absence of bubbles.

Fresh and fruity through richer and savoury

Some sparkling wines are light, fresh and fruit-driven. Others have more developed, bready or toasty characters, particularly after time ageing on lees.

Bubble size and persistence can vary. They are affected by dissolved carbon dioxide, pressure, temperature, the glass and ageing. Small bubbles alone do not prove that a wine is better.

Australian sparkling wine

Australia produces sparkling wine across multiple regions and styles. Verified examples include Tasmania, the Adelaide Hills and the Yarra Valley, with traditional-method wines particularly associated with some cool-climate Australian regions.

Australia also has a recognised sparkling-red tradition, especially sparkling Shiraz. This is a useful reminder that sparkling wine is not limited to European regions, pale colours or one set of grapes.

A simple way to understand the label

When you see a bottle of sparkling wine, consider four separate questions:

1. Where is it from? The region may influence the name and style.
2. How was it made? Look for terms such as traditional method or tank method.
3. How sweet is it? Words such as brut provide a clue.
4. What style is it? It may be white, rosé or red, and fresh or more developed.

Serve it chilled and pay attention to how the bubbles feel as well as how the wine smells and tastes. A narrow flute is not essential; the glass can influence how aromas and bubbles appear, but the wine remains the main event.

The short version

Sparkling wine is wine with dissolved carbon dioxide and noticeable effervescence. Its bubbles may come from a second fermentation in a bottle, a second fermentation in a sealed tank or mechanical carbonation.

The category includes white, rosé and red wines, from dry to sweet and from fresh to richly developed. Champagne is one protected regional type of sparkling wine—not another name for all sparkling wine.
