With many people cruising wine store shelves this time of year looking for a bottle of bubbly to celebrate the season with, it is a good time to examine how to identify the various types sparkling wine or Champagnie. There is no doubt about it; the sweetness classification system for sparkling wines is confusing. There are seven standard sweetness categories. Those are brut nature or brut zero, extra brut, brut, extra sec, sec, demi sec and doux. Each class indicates slight differences in aromas and flavour.

The sweetness level is determined by the dosage or liqueur d’expedition, which is a mixture of sugar and wine. It is used to top off the amount of wine in the bottle after riddling has taken place. Riddling occurs when the winemaker removes the dead yeast cells (referred to as the lees) from the neck of the bottle.

The dosage mix may contain anywhere between 500 and 700 grams of sugar per litre of sparkling wine. The precise ratio of sweetener-to-wine varies according to the producers’ desires and region the wine is produced in. Some producers use a sweeter liqueur d’expedition, while others choose not to sweeten their wines at all.

The classification system was designed a hundred years ago by the French to identify the sugar levels in Champagne. This is part of the laws that govern the production of Champagne. The laws have been modified countless times over the years.

The seven levels from dryest to sweetest are:

Brut Zero/Brut Nature

These wines are the driest, containing less than three grams of sugar per litre. These wines may also be referred to as “sauvage” or “zero dosage”.  They contain only natural residual sugar with no dosage added to the bottle.

Spanish Cava and Corpinnat producers may refer to these wines as “brut nature”, where in Germany the term “naturherb” may be used.

Extra Brut

In Champagne as well as Spanish Cava and Corpinnat, “extra brut”, or in Germany “extra herb”, is used to describe the second driest level of sweetness. These wines contain less than six grams of residual sugar.

Brut

“Brut” is the most common style of Champagne. To be labeled a brut wine, it must contain less than 12 grams per litre of sugar. This is a broad range and technically includes both “brut nature” and “extra brut”, so this category can vary widely in sweetness levels.

This term is also used to describe Spanish Cava and Corpinnat. In Germany the style may be referred to as “herb.”

Extra Sec/Extra Dry

“Extra Sec” or “Extra Dry” wines are slightly sweeter than “brut”. They contain between 12 and 17 grams of sugar per litre.  In Spain, the style is referred to as “extra seco” and in both Germany and Australia the term “trocken” is used.

Sec

“Sec” wines contain sugar levels between 17 and 32 grams per litre. These wines are considered to be ‘medium dry’ or ‘off-dry.’

Demi-Sec

Wines labeled “demi-sec” or Spanish “semi seco” contain between 32 and 50 grams of sugar per litre. Fun fact, this is equivalent to the amount of sugar in a typical gin and tonic.

Doux

This is the sweetest style of sparkling wine with the highest sugar content, usually over 50 grams per litre. Doux wines are very rare.
